CA18/208, flight day 223b/2018, Ontario, Canada

[dac]

Data location: /users/rsg/arsf/arsf_data/2018/flight_data/canada/CA18_207-2018_223b_Ontario

Data arrived from NERC-ARF via hard driver on 12/09/2018

Scientific objective: Canadian Wildfire Observations with SLSTR & Aircraft: Directional Effects of Thermally Emitted Radiation & Exploration of Flaming/Smouldering Partitioning and Plume Trace Gas Emission Ratios. Fenix and Owl data are being processed to aid geocorrection of other thermal sensors flown on the aircraft.

PI: Martin Wooster

BAS Project Code: D207

• Missing navigation synchronisation data
• Framerate not recorded correctly
• Missing log files for Fenix
• Navigation data (.sol format) and level1b (unmapped) data to be delivered first. The level1b data will be used to determine which lines map.

Sensors:

• Fenix (requested, flown)
• Owl (requested, flown)

[dac]

Fenix processing

Generating Level1b files.

[asm]

Extra checks

-Nav can't be used as stated above
-There are 11 owl lines and 10 fenix.
-All f98 files are empty
-6 different owl files have dropped frames
-Large differences on fps from fps_qpf in fenix line 18.
-Owl line 1 does not include the darkframes (separate file) and needs to be stitiched

[asm]

Owl processing

Only T2 for owl lines 7 and 1

[asm]

Owl processing

Symlinked missing T2 lines with the closest ones and also T1 for line 3. Stitched line 1 and creating the level 1b files.

Navigation Processing
Basestation and IPAS20 data are the same as flight 2018 223a (see ticket #648).
RINEX, GPB, PPP and SOL data has been copied from 223a into 223b.

Basestation PPP:

Latitude	51°04'01.40120"
Longitude	-93°48'14.26919"
Ellipsoid Height	346.797

[wja]

Note that header files show that 223a was flown before 223b

[asm]

General processing

Fenix hdr line 1 has the value for GPS Start time and GPS Stop time. Will edit the Stop time with the creation date.

Fenix/Owl Processing
SRTM DEM generated.

Hyperspectral & Owl Processing
Starting to process Fenix and Owl.

[wja]

Hyperspectral Processing
Level1b generated.
Lines 1 & 2 are too short for further processing. Number of lines in header files are 1401 & 428, respectively.
Finding SCT values of remaining flightlines.

Owl Processing
Using level1b previously delivered.
Lines 1, 4 & 6 are too short to be processed and further. Number of lines: 621, 609, 1084.
Finding SCT values of remaining flightlines.

Hyperspectral and Owl Delivery
Deliveries created for hyperspectral and owl data. Ready for checking.

[dac]

Fenix Delivery Check

Starting delivery check.

[dac]

Fenix Delivery Check

• check_apl_cmd ran through OK, had to use modified version with bands 153 94 53
• SCT values all look OK.
• Edges are very visible in mosaic, OK for this application though.
• Started zipping mapped files

Ready to deliver but hold off so can be delivered with Owl.

[dac]

Owl Delivery Check

• check_apl_cmd runs through OK
• SCT values look correct.
• Readme all looks good.
• Zipping mapped files.

Ready to deliver.

[wja]

Hyperspectral & Owl Delivery
Files were zipped successfully. Delivery has been placed on FTP slot 1 and notification e-mail has been sent to PI. Delivery finalised.
