CA18/208, flight day 227b/2018, Ontario, Canada

[dac]

Data location: /users/rsg/arsf/arsf_data/2018/flight_data/canada/CA18_207-2018_227b_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 227 (local time) but renamed as 227b (UTC)
• 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)

[asm]

Unpacking checks

-There are 15 owl lines and 16 fenix. Nav files have timepstamps.
-Owl lines 14 and 15 are missing T2 cal files.

[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:

Latitude	51°04'01.40104"
Longitude	-93°48'14.26882"
Ellipsoid Height	346.795

GNSS/IMU data processed and produced data has been put in relevant project subdirectories.

[asm]

Hyperspectral Processing

Have created DEM, apl config file and created mapped lines for a few SCTs for both Fenix and Owl. Have been suggested to prioritise project 229 so will leave further processing on hold for now.

Fenix/Owl Processing

Have taken over Owl processing.

Owl Processing

All bands mapped. Making delivery.

Fenix Processing

There are two areas covered by the flights. The south one is too cloudy to find SCT values. Only processing north site (lines 10 - 16). Found SCT values and mapping all bands.

Fenix Delivery Check

• Logsheet:
  • Logsheet first page looks like Owl information.
  • Fenix flightlines are seemingly titled one more than their associated Owl lines. f15 = o14, f16=o15 etc. This should be shown on logsheet second page.
    
  • Flightline 16 has been omitted from processing and is not on the logsheet. The other lines which have not been processed should be removed or they should all be present and aligned with the associated Owl line.
• ReadMe:
  • ReadMe data quality comments needs to mention the fate of flightline 16.
• Z-values:
  • All processed lines are completely dominated by underflows (apart from fire) in bands greater than ~350. This is shown in ReadMe, but is it expected?

Everything else looks ready to deliver

[wja]

Owl Delivery Check
Starting delivery check.

[wja]

Owl Delivery Check
Please review SCT values for flightlines: 5, 12, 13 & 15.

[dac]

Fenix Delivery

• Left frontpage in logsheet as Owl info but fixed Fenix filenames so they correspond to the correct files, also updated readme.
• Line 16 didn't process due to navigation going backwards error. Forced and found SCT (updated table above). Added to delivery.
• Added comment about underflows in SWIR bands due to low integration time.

[dac]

Owl Processing

Rechecked SCT values for specified lines and updated. Edited previous table. Remapping all bands.

[dac]

Owl Processing

Created new delivery with updated SCT values. Retained readme and logsheet from previous delivery. Ready for checking to be resumed.

[wja]

Delivery Check
Please check Owl flightline 5 SCT and Fenix flightline 12, they look inaccurate in the check_apl_command outputs.

[dac]

Fenix and Owl Processing

Redid Owl line 5 (processed using incorrect SCT) and found better SCT value for Fenix line 3 (table above updated). Updated delivery, ready for checking again.

[wja]

Hyperspectral Delivery Check
Updated flightline 12 looks good and the metadata *xml has been updated.
Ready to deliver.

Owl Delivery Check
Assuming Owl delivery check.

[wja]

Owl Delivery Check
Spectral is fairly noisy, as expected from the short integration times. Bad pixel are also present but are mentioned in ReadMe.
Ready to deliver.

Hyperspectral & Owl Delivery
Data placed on FTP slot 1. Notification e-mail sent to PI. Delivery finalised. Processing directory tidied.
