4 years ago Welcome to satpy @Aang23! At the moment, I think the only raw data we support is HRPT from NOAA, and we just extract AVHRR from it in the reader.
Can you do the same for MetOp with all supported instruments?
We don't have the code to do it now, but it sounds definitely interesting, if you want to give us a hand with that :) In the case of AVHRR, that would imply two things (after decoding the AHRPT stream and getting the channel data, the telemetry and the time):
- first navigate the data. This should be doable with data pyorbital (see the hrpt reader), although I thing the yaw steering mode Metop uses isn't implemented yet (shouldn't be to hard to add though)
- then calibrate the data. The calibration procedures are already implemented in pygac, so we can just use them.
Or does it need to be processed in a specific way before doing so?
As far as I know, the Metop AVHRR data we process in satpy can come from two sources:
- Eumetcast, in which case the data is in EPS level
- Direct reception station, and then processed with AAPP software (from the NWPSAF project).
Keep us updated on which way you go!

I am looking to process data acquired by my own amateur station from the AHRPT downlink. I see this is supported for FengYun as long as you can provide raw CCSDS data (which I can).
