Description (last modified by wja)

Data location: /users/rsg/arsf/arsf_data/2021/flight_data/sweden/Magic-2021_235a_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

Navigation Processing

Navigation data for this flight is for the whole day. This includes flights 235a, 235b, 235c & 235d.

Single basestation method used. KIRU station downloaded from epncb.eu with the following:

lftp epncb.eu:/pub/
cd obs/2021/235
mirror --include-glob=KIRU* ./

RTX coordinates computed for KIRU:

  • Horizontal sigma: 0.004 m
  • Vertical sigma: 0.005 m

POSPac recommended cutting the following seconds from the begining and end of the flight (as the flight path goes over the KIRU station between data collection and take off / landing.

Current Start:	112733.000	Recommended Start:	113688.000
Current End:	126634.000	Recommended End:	125868.000

Horizontal RMSE generally below 3 cm. Start of flight and peaks up to 6 cm.
Vertical RMSE generally below 5 cm, several peaks up to 7 cm.

Hyperspectral Processing

All flightline processed with just 3 bands (RGB).

Data looks noisey.

Started.
-No mosaic in Readme file
-No sensor files. Copied those to start running apl checks.

There is a small offset between lines. It is minor but visible as there are not many features. Some lines do overlap better (7 and 8) and others is more obvious (5 and 6). This is likely due to the basestation and the DEM and I personally think it can be delivered but a note in the readme might be worth.

-Very low signal and very noisy data (bining 2). The only bands with no underflows are between 70-225 (out of 594).
-Py6S: matching in the VNIR but much lower than expected. Clearly visible and nothing very usable in the SWIR.
-Please include note about noise and low ilumination in the readme
