SwathS, flight day 150/2023, Grosseto

[jann]

Data location: /users/rsg/airborne/2023_arsf_data/flight_data/italy/SwathS_23-2023_150_Grosseto

Data arrived from NERC-ARF via hard drive September/October 2023

PI: Martin Wooster

Sensors:
Fenix1k (requested, flown)
IBIS ( main requested, flown)
OWL ( requested, flown)

[jann]

OWL: Some lines don't have nav data, these are data recorded in Siena.

Final checks - warning about the real time navigation time stamps was flagged.

Navigation Processing

Basestation data converted to RINEX. All previous flights are also included in the basestation data, so just this flights data needed to be extracted (done with teqc).

GPS and GLONASS broadcast ephermides, along with precise ephemeris data accessed from CDDIS. PosPac could not access these itself.

Completed processing using the single base method.

[jann]

Flightlines 1-29 only being processed, the remainder, lines 30-41 were recorded in Siena and have no nav data.

[jann]

Radiometric calibration completed, waiting on boresight.

[wja]

Fenix1k Processing

Geoaccuracy looks great, but the swath mask needs updating (looks like this will be the case for all flights between jdays 143 - 152).

[wja]

Fenix1k Processing

Line 7 was recorded when IMU was not facing nadir. Cannot map.

[wja]

Fenix1k Processing

Geoaccuracy is not perfect but is not bad. Looks like a slight SCT and/or boresight error throughout.

Processing all bands

[wja]

Line 4.0 failed. Reprocessing.

Owl Delivery

Jane created a delivery and I have added a readme and logsheet. This should be ready for DC now so will mark as such.

Delivery Check

Starting delivery check

Fenix1k Processing

Line 8 is when IMU is directed at an angle. Will not processing.

[wja]

Owl Delivery

Delivery looks good.

Updated logsheet to include view angles.

Zipping mapped lines.

Marking ready to deliver.

Creating Fenix1k Delivery

Owl Delivery

Put on FTP slot 1. PI notified.

Fenix1k Delivery

Ready for checking

Fenix1k Delivery Check

• Delivery had fodis folder, have removed
• Spectra look good using Py6S checker script
• check_apl_cmd ran through OK.
• Geolocation in line 7 (both parts) is way off, looks too far south
• For line 5 part 1 it looks like the timing is slightly off towards the north, part 0 looks good so it could just be due to the length of the line and not much we can do about it.
• Other lines looks good and align well with Owl from the quick check I did.
• No geometry files. Think they are only needed for Owl but might be worth mentioning when delivering

Once line 7 is fixed then is good to go.

[wja]

Fenix1k Delivery Check

Line 7 was recorded when the IMU was directed at and angle. Will remove mapped and nav data and add a note in the Read Me.

Line 5 and Line 8 show flight timing errors. However, I think this is a FPS issue (or a combination of both) as both are worse at the end of the line compared to the start. Nevertheless, they match well with the owl data so will include with a note in the readme.

Will let PI know about absense of geometry files when delivering.

Zipping mapped data

Fenix1k Delivery

Marking ready to delivery (when zipping is complete)

[wja]

Fenix1K Delivery

Added geometry files (aplcorr --atmosfile outputs) to the deliveries at PI's request.
