     11 Today is the last day of the NERC ATSC summer school in Barrax, Spain. During yesterday’s flight (15.06.17) we supported 22 scientists on the ground with a series of flights over nearby Las Tiesas farm site in Barrax, Spain, using VNIR, SWIR & LWIR instruments (and a 100mp digital camera). This was part of an NERC ATSC summer school and although very hot both the field and airborne surveys were a success.  Today we are conducting three flights separated through-out the day to investigate land surface temperature (LST). The key airborne instrument in our suite for this is our LWIR imaging spectrometer (Specim Owl). This group (separate from the summer school and led by Martin Wooster) seek to develop methods for deriving LST/surface spectral emissivity algorithms for retrieving LST and SSE simultaneously and has the potential to validate satellite-based retrieval of LST and SSE.
     13Tomorrow (17.06.17) we plan to fly over a study site near Valencia to collect data for the validation of the operational and user-generated vegetation products derived from the optical instruments on-board ESA’s Sentinel-2 and -3. This is to support another project in this area (and supports work by a research team led by Jadu Dash).

    818''On Sunday (27.09.15) we commenced support of HYMOSENS2. This EUFAR funded project is focused on the collection (and analysis) of hyperspectral data from rivers in the Ain / Rhȏne-Alps region (Eastern France). With much consultation with the research team in the field, after several delays due to French air traffic control, instrument problems and persistent cloud over the site (which led to one aborted survey) a two and a half hour survey was flown. However, only part of the area was covered (16 of 30 lines), the river water levels were unusually high and the later part of the survey was outside the desired two hours after solar noon. This later issue was relevant as the project required high quality spectral data and the flying altitude was very low which reduces the strength of the signal from the imaging spectrometers. Nevertheless, discussions with the research team identified a solution which was enacted a couple of days later (on the 29.05.15).''
    1424''Tomorrow we plan to relocate to Toulouse but will check the Alps on route with a view of collecting more data from that area if conditions allow.''

    1727''On Wednesday (23.09.15) we transited to Palma in preparation of supporting Med2hyCon, a EUFAR2 funded project in Mallorca. We arrived in Mallorca before the airport became busy over the weekend to improve our chances of access to the air space for aerial surveying. Unfortunately cloud cover prevented data collection on the 24.09.15 and had been present on preceding days. However, these conditions improved on Friday (25.09.15) and we were able to conduct a three and a half hour survey at two altitudes in a part of the island away from the main airport traffic under good conditions. These data included 27 flight lines of Fenix (VNIR & SWIR) data, LiDAR data & digital photography. These data will be used to investigate sediment movement, debris stability and vegetation health in this river catchment.''
    2030''Our pilots tried to obtain permission from local air traffic control for access to some requested study areas close to the main arrival and departure tracks into Palma airport and had another attempt this morning (Saturday, 26.09.15). However, because the Mallorca airspace that serves Palma airport is very busy (handling more than 700 aircraft a day), permission to fly within the restricted areas has not been granted. Therefore we have re-deployed to Lyon in anticipation of supporting HYMOSENS2 tomorrow (Sunday, 27.09.15) and ISOTHERM the day after (Monday, 28.09.15) should the forecasted weather remain favourable. If conditions do not prove to be suitable we are poised to remain in Lyon for a few days to take advantage of any opportunities that should present themselves. However, once our work in the Lyon area (HYMOSEN2) are and the Swiss Alps (ISOTHERM) is complete we will proceed to Toulouse for support of the final project in this EUFAR2 campaign (AHSPECT).''

    2333'' Following the replacement of the nose-wheel tires solved the problem and we were able to collect data from the EUFAR Holuhraun site late on the 4th of September. Cloud prevented completion of this project. However, on the following day (05.09.15) we returned and collected VNIR, SWIR and LWIR hyperspectral data (Fenix and Owl), LiDAR and digital photography. This completed this project. On the return flight we were able to collect LiDAR data on from three of the remaining four flight lines from the Hekla site.''
    2535''The weather prospects for the following days (06.09.15) were very poor and we laid plans to depart to the UK but conscious of the changeable nature of the Icelandic weather we were able to delay and when conditions contrary to the forecast emerged at the study site were able to fully support both areas of interest with all instruments. Consequently data were collected in support of all the projects and the team (and aircraft) returned to Cambridge today (07.09.15). The return flight was approximately 6 hours and 30 minutes with a fuel stop at Prestwick part way.''

    2838''On the Sunday (30.08.15) we were able to conduct a 2 hour survey over Hekla but the conditions were not good and the following day (31.08.15) the weather conditions did not allow any data to be collected. However, on Tuesday the 1st of September conditions improved. We conducted a 5 and a half hour survey over Hekla from early morning until early afternoon. Despite the Owl’s thermal calibration failing and heavy rain in parts the survey over this site is now substantively complete. The LiDAR coverage is good and we will endeavor to complete the last four lines if the weather and time allow. Flight data possibilities have been discussed fully with the PI and survey objectives have been matched to available weather opportunities.'' 
    3242''Unfortunately a problem with the aircraft became evident during take-off and landings. Minor investigations were made between the flights but these did not solve the problem which was judged potentially serious enough to require an engineer to attend to replace the nose-wheel tires. These were ordered from the UK, arrived yesterday (03.09.15) and should be fitted this morning. If this solves the problem we hope to return to Holuraun this afternoon (04.09.15). Nevertheless, the break in operations has been matched with bad weather over all our study sites but did allow us to property download and back-up data and allowed the Hekla field team to view the aircraft and instruments yesterday afternoon.''

    3545''After a series of delays, partially due to poor weather in Iceland, the aircraft deployed to Reykjavik on Thursday the 27th of August. This was to support an EAA Rannis grant for airborne data from Hekla and two EUFAR funded projects. Immediately prior to departure a BBSRC grant (to study ash die back) was supported but two other grant funded projects were not supported due to persistent bad weather in the UK but we hope to do so once we return from Iceland.
    3646Yesterday (28.08.15) we able to conduct our in-county preparations and today (29.08.15) we managed two surveys over Hekla with a combined flight time of almost 7 hours during which we completed approximately half the project (28 of 54 flight lines) including the challenging top of Hekla than is normally covered in cloud. LiDAR, digital photography, Fenix (VNIR and SWIR) data were collected as well as selected areas of Owl (LWIR).''
    3949''The aircraft and instruments are performing well and the three person crew remain well but very busy. The scenery remains stunning and the Icelandic people very friendly.''

    4254''Today (02.11.14) we once again deployed for a dawn take-off but our eyes-on-the-ground at Danum Valley (Abdulla), was able to inform us of heavy cloud cloud. This was of course only evident in daylight. However, condition were steadily improving and his observations from the previous day in Danum Valley indicated that condition may clear later in the day. We took-off at 10:00 hrs and were able to collect ten flight lines of very good data from the key area around the research centre in the period around solar noon. This survey supported MA14-11 with the key area also supporting RG13-06 (the BALI NERC grant funded project). Tomorrow (03.11.14) we hope to deploy at 07:00 hrs to make full use of this potential opportunity of relatively cloud free conditions to complete the survey of this site.''

    4557''Today (30.10.14) we were able to fly 42 flight lines over the Maliau Basin. Take-off was once again just after dawn and allowed us to complete the data collection (LiDAR, Fenix and Owl) for this site before the build-up of cloud covered the study area. Completion of this area is a huge relief as we have been aware that is was the most prone area to persistent cloud and it forms a significant study area for the NERC Biodiversity and Land-Use Impacts on Tropical Ecosystem Function (BALI) project. Our dedicated representative on the ground (Abdulla) is now able to return to Danum Valley (also in Sabah) where we intend to collect the next set of airborne data.''

    4860''Today (25.10.14) our five hour flight started with another dawn take-off from Kota Kinabalu. It is with great relief that I can report that it yielded a three hour survey, with LiDAR, Fenix and digital photography, that concluded our data collection from the SAFE a site (in support of the NERC BALI project).  We collected data at three different altitudes, ~3000ft, 7000ft and 9000ft, and were able to make full use of the experience that we have gained from flying this site in terms of the relative speed of cloud build up over the different areas . Tomorrow, the crew will take a well needed rest while our stalwart colleague (Abdulla), who has been manning the gps and sun photometer in the field, relocates to the Malaiu Basin (also in support of the NERC BALI project). This will be our focus of operations on Monday.''

    5163''Yesterday (17.10.14) we continued our strategy of early morning data acquisitions from the SAFE site (in support of BALI, the core NERC grant). With engine start at 07:00 (local) within a 4 hour flight we had 3 hours of data collection on site. During this time we completed the last 5 five of 25 long altitude lines that formed an overview of the SAFE site and three of various mid altitude areas within the SAFE site. These data comprised of LiDAR, Fenix (VNIR & SWIR), Owl (LWIR - for some lines) and digital photography. Last night we were rewarded with a particularly spectacular sunset.''

    5971''Over the last few weeks we have had an intensive period of flying to take advantage of the encouraging weather conditions.  Our support of the Wessex BESS project (RG12-09) continues and following a month of standby and aborted flights on weekends (in periods when the ranges are cold). We hope to complete the spring/summer component of this project in forecasted good weather this Saturday (21.06.14).  This month much of our activity has been focused around the support of GB13-01, a grade 9 project mapping ecosystem services on agricultural land in Suffolk.  The four sorties that we have had in support of this project have been limited by a build up of Cumulous late each morning. However, during this period we have also managed to collect to support a project in water meadows near Wytham Woods in Oxfordshire (GB13-10) with an early June acquisition and full waveform data from Merthyr Tydfil (BGS12-01).''
    6577''In between the flying, other activity being persuaded this month has included: flight planning for the AirSAR flights next week, continued preparations for the Malaysian campaign and the atmospheric work in July (in the UK) and yesterday (18.06.14) receipt of the finished Radome.''

Thursday morning started with thick cloud and heavy rain and progressed to overcast with periodic showers. These poor conditions were forecast to continue for several days.  Therefore, we returned back to the UK in readiness for UK data acquisitions this week.''

    86100''As you maybe aware (from conversations or from the recent data processing worshop at PML) our regular laboratory calibration showed that, over the past year, the sensitivity of the Eagle dropped to an unacceptable level for collecting data from the UK. We have an agreement for a replacement instrument (a Specim Fenix) which will be delivered at the end of the year. In the interim we will operarte loaned Eagle and Hawk sensors.  Unfortunatelly, the final confirmation of arrangements was delayed in the recent political turmoil and these are yet to be despatched. Once they arrive in Gloucester we will have to calibrate the instruments, fit them into the aircraft and boresight them.  This means that we will not be able to collect data next week. It is hoped that we will be able to collect data from the start of April but I will try to keep you informed. We will have a better idea of timmings once we have received the loaned Eagle and Hawk instruments at Gloucester.''

There followed a long flight to Kartome (Sudan) for a quick tech stop and then on to Luxor (Egypt). Most of the six hours of flying were across the featureless Sahara so our overnight stop-over in Luxor will have a slightly later departure (~noon) to allow the crew to recover for the next stage. This has also allowed us to watch the sun set and sunrise over the Nile.''

However, despite the sad news in regards to the two projects in Italy, this means that we will be available to resume our support of the various project based in the UK that have not been supported due to the generally poor conditions over the summer. I anticipate that the Italian projects will be rolled-over for support in 2014.''

The flight duration was 4 hours and 20 minutes, most of this was at 18000ft, on oxygen. Each of the long flight lines took 20 minutes to complete, we completed 12 such flight lines and a cross line. The area surveyed constituted approximately a third of the site. The conditions were hazy with isolated and localized  low cloud and haze. This relates to a static high pressure system that has restricted us since Sunday. ''

This allowed data to be collected from all 6 of the individual high priority study sites during a 4 hour flight. Although the order in which data were collected from the individual sites needed to account for cloud build up and dispersal all collected data were of good quality with minimal obscurement of the ground targets. In addition to LiDAR and RCD photography, 5nm Eagle (VNIR) and 6nm Hawk (SWIR) hyperspectral data were collected.''

Forecasts, supported by field observations by the PI, indicated two possible opportunities (03.07.11 & 04.07.11) but when we visited the area the study sites were obscured by cloud. We are not restricted by time of the day as their is constant daylight and the airport has some flexibility for late and early flights. However, a high and low layer of cloud persists with the lower layer between the aircraft and the ground. The ground height prevents us from flying any lower but because the focus of the science is LiDAR and photography the upper cloud layer is less of a problem. Today's forecast is not hopefully but there may be an improvement tomorrow.''

The survey straddled Solar noon and avoided most of the surrounding cloud. No clouds were present below the aircraft but some cloud shadow was present in the North West corner (in the last four lines). Some shadowed ground is observed (without shadow) in adjoining Eagle lines due to the high side overlap. Nevertheless, if the forecasted good conditions are present on Wednesday (29.06.11), we hope to collect good data from the previously obscured area.''

    521541''Over the last week the ARSF have been waiting for clear conditions for several study sites. These were in London, Wales and Scotland. Support of GB08-19 (London) requires near solar noon clear condition, a preceding period of dry weather and clear, dry conditions for the following night. At this stage in the season GB09-04 (Coed-y-Brenin) and GB09-11 (Abernethy Forest) are basically LiDAR surveys (with photography if possible) and require clear condition between the ground and aircraft (night or day). These areas have not presented suitable opportunities. However, an additional data collection requirement was presented by the floods in Cumbria (UR10-01).  We launched on the weekend but were unsuccessful in our attempts to collect data from this site. A second attempt to collect data from the area is being made this evening in the hope of catching a potentially cloud free window between 21:00 and 00:00 hrs.''

However, conditions look encouraging for London on Thursday and Friday and some forecasts indicate that the South of England may be clear on Thursday morning; the West of Scotland may be clear on Friday morning; the East of Scotland clear on Sunday morning and the Peak district and North/West Wales on Monday morning. If conditions continue to be forecast as good for London on Thursday, this will be our primary site from which we will direct our data collection efforts.''

    824844''Although some regions in the UK have had good weather during the last few days most of the key science project sites have been in areas where cloud has been present. Nevertheless, the ARSF are not available for the collection of data, the hyperspectral instruments are undergoing calibration / validation with FSF and the Optech LiDAR continues to be in use by its owners at ULM. Remote sensing is due to resume on the 11th of August. During August (after 11.08.08) we will endeavour  to collect data from the Midlands, North/West Wales, Cumbria and Scotland. However, during this period our priority sites will be London (in support of GB08-19) and Iceland (in support of IPY07-09). An emailed indication of our flying timetable based on forecasted weather conditions should be distributed in the first week of August. If any research team that anticipates having data collected from their site/sites needs further information then they should contact Gary Llewellyn on 079 1969 7851.''

    827847''Yesterday (14.07.08) a failure in the AISA Eagle control system cause us to abort an attempt to collect data from the North bank of the Thames; this problem has been corrected. Unfortunately, despite the present good weather in the South and East of the UK conditions continue to be unfavourable in the Midlands, Cumbria and Scotland. We hope to be able to collect data from Wytham Woods and the Thames this week, however, the passive remote sensing instruments are due to be removed from the aircraft on Friday (18.07.08) in preparation for calibration/validation with FSF in following week. The research teams for one of the Peak District (GB08-02) projects and the project based in North Wales (GB08-13) have deferred the next collection for these projects to August when data collection (with the LiDAR fitted on DCALM) should resume on the 12th of August (12.08.08).''

Our intention is to support projects in Cumbria and Scotland in the coming week. However, support of science in North Wales continues to be problematic. The collection of remotely sensed data should continue until the long overdue calibration/spectral validation of the AISA Eagle and Hawk (21/06/08) and should resume with the LiDAR unified with the other instruments on the Dornier early in August (11/08/08).''

Contact with research teams, RSPB shops and regular evaluations (based on webcams and a range of weather observation and forecasting websites) did not indicate that conditions would improve before dusk. We hope to be able to support these projects in the next seven days.''

    839859''During yesterdays flight the belly-door that protects the remote sensing instruments during take-off, landing and transit seized to the point of not opening. This problem only manifested itself when the aircraft was airborne; therefore it was not identified in the ground checks conducted after the latest sequence of maintenance work. An engineer has arrived from Germany to repair the fault and we hope to be collecting data as soon as possible.''
    841861''The Optech Airborne Laser Terrain Mapper 3033 will not be available for fitting in the Dornier until the middle of August 2008 and will be returned to its owners after five weeks. Within this time period data were planned for collection from the French Alps and Iceland. Some of the most highly graded projects that require the repeat acquisition of LiDAR data will have those data collected coincidentally in another aircraft by a subcontractor.  Some projects that relied on LiDAR data (especially those with multiple acquisitions or those that cannot be supported between 15/08/08 and 11/09/08) will not be supported in 2008. Those projects that had LiDAR data as a primary component and were awarded a low alpha four grade in the 2007/2008 application/review round will not be supported in 2008 and will not be rolled over for collection in 2009. Those projects awarded a mid alpha four grade or higher for which we have been unable to make special data collection arrangements for will be rolled over to 2009. Where a project retains its scientific justification without LiDAR data the ARSF will endeavour to support it as best we can.''

This resulted in greater availability of the aircraft in the support of UK remote sensing projects. However, the three days of clear, bright conditions (6th, 7th & 8th) have allowed many of the UK projects with multiple acquisitions to be started. Unfortunately this period was too late for some projects in the South of England that needed 'leaf-off' conditions. Data were collected on all of the clear three days and pre-dawn on the 9th.''
