| | 8 | ''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).'' |

| | 10 | ''On Monday good conditions in the Alps allowed support of ISOTHERM. This three and a half hour survey sought to collect data from several sites in the Alps surrounding Mont Blanc. The first site, Mer de Glace, was very turbulent but eventually all nine flight lines were collected. The flight crew discussed their concerns but evaluated the conditions to be borderline but definitely safe but collected the last line later in the flight, after the level of turbulence had lessened. The next site (Aiguilles Rouge was covered in cloud but were able to collect twelve lines of data from a third site (Argentiere) before cloud needing to refuel. Another five lines were collected after refuelling but by then cloud was beginning to claim the cover the sky and this survey was concluded after two hours. LiDAR, Fenix and digital photography were collected.'' |

| | 12 | ''Today (29.05.15) we were able to return to allowed the HYMOSENS2 site and collected twenty three lines (including two repeats and a cross line) of LiDAR, Fenix (VNIR & SWIR), Owl (LWIR – not covered in the EUFAR agreement) and digital photography in two and a half hours of flying all within two hours of solar noon. These data were collected at just over 2300ft so a high illumination was essential to preserve the already low signal available from the altitude.'' |

| | 17 | ''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.'' |

| | 20 | ''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).'' |
