CA18/208, flight day 225a/2018, Ontario, Canada

[dac]

Data location: /users/rsg/arsf/arsf_data/2018/flight_data/canada/CA18_207-2018_224a_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

• Labelled as 224b (local time) but renamed as 225a (UTC)
• Missing navigation synchronisation data
• Fenix line 9 didn't have a log file so made a dummy one for renaming
• 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)

Unpacking checks

-There are 12 owl lines and 12 fenix, navigation files don't have timestamps. Will need to find SCTs manually.
-Only T2 cal files for flightline 1, 3 and 4. There is a different of roughly ~45 minutes between line 4 and last line so this is above the 30 minutes window that Specim suggests.
-Dropped frames:

-Fenix: 2 incidents for f8, 2 for f5.
-Owl: 3 for o1, 2 for o3, 5 for o4, 1 for o5, 28 for o6, 4 for o8, 2 for o9, 1 for o10, 3 for o11 and 1 for o12

[asm]

Owl processing

Symlinked missing T2 owl files using existing ones for processing purposes and renamed the files according with the flightline number.

[asm]

Owl Processing

Started in order to create the level1b files.

Navigation Processing
Basestation PPP identified as:

Latitude	51°04'01.40004"
Longitude	-93°48'14.26963"
Ellipsoid Height	346.818

[wja]

Navigation Processing
GNSS/IMU processed in IPAS TC.
Height position separation exceeds 0.05 in places but otherwise solution looks good.
RINEX, GPB, PPP and SOL put in relevant locations in the project directory.

[wja]

Fenix/Owl Processing
SRTM DEM generated.

[wja]

Owl Processing
Starting Owl processing.
This is a night flight, so once Owl SCT values are identified, Owl flightlines will be used to find SCTs for Fenix.

[wja]

Owl Processing
Owl SCT values (0.05 precision):

1	4.55
2	4.55
3	5.00
4	3.80
5	4.50
6	5.35
7	4.55
8	5.45
9	4.50
10	4.90
11	4.40
12	5.35

Will identify Fenix SCT values Owl data using these offsets.

[wja]

Fenix Processing
Lines 1-3 & 6-7 do not appear to have any features. These will be omitted from further processing.
Fenix SCT values identified:

1	N/A
2	N/A
3	3.00
4	2.75
5	N/A
6	N/A
7	N/A
8	38.35
9	N/A
10	108.40
11	3.30
12	3.00

Processing all bands.
Will start creating Fenix & Owl deliveries.

[wja]

Fenix/Owl Delivery
Processing complete, generating delivery.
Creating logsheet.

[wja]

Owl & Fenix Delivery
Owl and Hyperspectral deliveries are ready for delivery check.

[dac]

Fenix Delivery Check

Starting deliver check.

[dac]

Fenix Delivery Check

• Readme looks good.
• Removed fodis directory
• Ran check_apl_cmd using bands used for quicklooks, can't see much but features which are visible line up between lines.
• Data are very noisy but this is explained in the readme.
• Started zipping files.

[dac]

Owl Delivery Check

Starting delivery check.

[wja]

Owl Delivery Check
Reprocessed flightline 7. Navigation and mapped data with correct SCT value has been added to delivery.

[wja]

Owl Delivery
Zipped mapped flightlines.

[dac]

Owl Delivery Check

Resuming delivery check.

[dac]

Owl Delivery Check

• Results from check_apl_cmd look better now navigation has been updated for line 7. Existing metadata is fine as lists the correct SCT value.
• Everything else in delivery looks good

Ready to deliver.

[wja]

Fenix & Owl Deliveries
Placed on FTP 1. Notification sent to PI (along with 233b). Delivery finalised.

Archiving
JSONs created and added to PostGIS. In the queue to rsync to CEDA.
