HyTES/19, flight day 180b/2019, Grosseto

[wja]

Data location: /users/rsg/arsf/arsf_data/2019/flight_data/italy/HyTES19-2019_169_Grosseto

Data arrived from Kings College London via hardisk on July 15 2019.

Scientific objective: Joint NASA and ESA campaign flying JPL’s HyTES thermal instrument over sites in Europe with a focus on crops and soil. Aim is to inform the future Land Surface Temperature Monitoring (LSTM) satellite mission. The NCEO Fenix instrument was flown alongside HyTES to provide visible – SWIR hyperspectral data.

PI: Martin Wooster

Sensors:

Fenix (requested, flown)

Unpacking
Includes several sites including:

• Redmere
• The Fens
• Milton Keynes
• Duxford

[wja]

Navigation Processing
OS Basestation RINEX data downloaded for station SNEO, NEWR & BUCI as noted on flight logsheet.

[wja]

Navigation Processing
Have downloaded GPS nav data 'brdc180.19n' from CDDIS's FTP. ​https://cddis.nasa.gov/Data_and_Derived_Products/GNSS/broadcast_ephemeris_data.html

[asm]

Nav Processing

Navigation processed via PPP. Accuracy looking good:
-Lat and lon sepparation under 0.05m and height separation under 0.08
-Position accuracy under 0.020
-Everything else looking good

Logsheet Creation

Log sheet created, however, flight-lines plot not generated so have included Flight KML.

Hyperspectral Processing
Started processing Fenix data to level three.
replace_wavscale.py has been run on the raw data - note that flightline 8 has differnt spectral binning with 448 bands.

Hyperspectral Delivery
Just needs updated calibration and data quality reports.
Everything else is ready for checking.

Delivery Check

Starting Delivery Check

• Missing line information for flightline 1
• check_apl_cmd didn't run
• Line 3 has undetected underflow bands 372-379
• Line 4 has undetected underflow bands 370-387
• Line 6 has undetected underflow bands 415-439
• Line 7 has undetected underflow bands 415-439
• Checked vegetation spectra against Py6S. Good match, a bit low in the SWIR with the exception of lines 1 and 2 that are completely underflowing and doesn't look to have usable data as analysis on tuiview with asm revealed

[seg]

Delivery Check

DC finished*. First for seg, please have a second look

[asm]

Delivery Check

Already started. Having a second look as it is first seg's DC.

[asm]

Delivery Check

-check_apl_cmd running just fine, needed to use correct hyp_readme file.
-SCT look correct and with no offset
-re-created the flightline 1 xml file
-Looks like problems with the SWIR are caused by a too small integration time selected (minimum possible selected, over 200 times smaller than lines 6 and 7). This is likely caused by an human error, I will add that into the readme
-Every other check has been carried out, all correct.

I have updated the Readme to meet my comments and @seg. I will leave this project on hold for now to double check if it is worth deliver flightline 1 and 2 as they are or if we should drop the SWIR region. Once resolved and mapped files zipped, it should be ready to be delivered.

[asm]

Fenix Delivery

After some discussing, we decided to mask out the SWIR bands for lines 1 and 2.
-Created new mask files
-Created new mapped files
-Moved new files to the delivery
-Updated the readme accordingly
-Added xml for line 5 as it was missing

Seg will have a second look as a DC and if everything is correct, should be ready to deliver soon.

[seg]

Delivery Check

Everything looks good

[asm]

Fenix Delivery

Mapped files have been successfully zipped. Marking this project as ready to be delivered.

Atmospheric correction
Atmospheric correction has been applied to create level2 and mapped data.
