Description (last modified by wja)
Data location: /users/rsg/arsf/arsf_data/2021/flight_data/sweden/Magic-2021_234_Kiruna/
Data arrived from Kings College London via hardrive from Sweden on September 20th 2021.
Scientific objective: International project (includes NASA, CNRS, ESA, DLR, Eumetsat) to monitor and identify methane inventories in the arctic. JPL's HyTES instrument was utilised. A total of three aircraft were used to collect data, along with deployed balloons and ground measurments.
PI: Martin Wooster

Nav Processing
1 Wanring when importing nav data:
42434.000 : WARNING : Gap of 87.0 seconds in GNSS navigation data
42434.000 : WARNING : Gap of 87.0 seconds in GNSS observables data
Start end time of navigation data (GPS seconds of week):
GPS Week: 2172
Start: 42266 (22/08/2021 11:44:08)
End: 55431 (22/08/2021 15:23:33)
Warning occurs 168 seconds into the flight (2.8 mins) - likely before take off.
Downloaded basestation KIRU from epncb.eu:
lftp epncb.eu:/pub/ cd obs/2021/234 mirror --include-glob=KIRU* ./
Computed RTX coordaintes for KIRU:
- Horizontal sigma: 0.004 m
- Vertical sigma: 0.005 m
POSPac recommend to clip the ends of the nav data for processesing so it is closer to the basestation:
Current Start: 42248.000 Recommended Start: 43418.000 Current End: 55414.000 Recommended End: 54660.000
Data quality:
Horizontal RMSE < 1 cm apart from one spike at 3 cm.
Vertical RMSE < 2cm apart from one spike at 5 cm

Hyperspectral Processing
Processed all flightlines with 3 bands (RGB) to check geoaccuracy.
Flightline 2 part 2 is very green. Unsure why this is exclusive to this section of the flightline.

Hyperspectral Processing
3 band data is fine. The green nad red was just a result of contrast stretching done by Tuiview.

Digital Camera
Started converting raw PhaseOne images to Tiff.

Delivery created.
Ready for Delivery Check

Delivery check
Started
-4 missing xml line information files. check_apl_cmd skipped those
-Very low signal, mostly only underflows even with bining 8 on the VNIR and large integration times. Near no data over 1500nm in the SWIR.
-Py6S shows shape matching in the VNIR but no where near in the SWIR.
-Please add note about data quality in readme
comment:9 Changed 3 years ago by wja
- Added the missing XML files (mako wasn't installed on one of the gridnodes)
- Added underflow / noise note in the readme
comment:10 Changed 3 years ago by wja
- Specifically mentioned SWIR bands being badly affected by underflows / noise in readme.

The xml for line 4 is fine now. The readme looks good. I have now zipped the files and those were zipped correctly. I will mark this dataset as ready to be delivered.
