Re: Pytroll/Satpy Metop composite

Ferdinand Valk



I encountered one complication for the Metop stacked passes. In the single pass version the avhrr_l1b_eps.yaml reader accepts the bz2 file type, however for the multi-pass it expects uncompressed files instead. I could not yet find out why that is.

For proof of concept I uncompressed a day worth of Metop-B data and then the script completes correctly (obviously adapt this to your local paths).

Attached is both the Metop script and a stacked eurol image.




Do you know why there is a behavioral difference in avhrr_l1b_eps.yaml between single and multi-pass?

OK, so indeed you were talking about something else than I understood. I can have a look at it tomorrow. Should be quite straightforward.

ah…sorry…indeed, there is no stacked Metop script, you are right. 

Maybe Ernst will add one if he has time for one Metop sat and we can adapt this for the other two…? 

But we already have NOAA-20 and NPP what is quite nice. :-)

Yes, I started to work and the starter kit is simply wonderful. I'm using the LEO e and GEO scripts adapted for my coordinates. I was wondering if there's a script (like noaa20 and suomi) for metop (A-B or C) composite of the day (or night). Also something regarding Noaa19.


Thanks for reply Ferdinand

I understood that you have started up to work with pytroll/satpy based on the HowTo version 3 from Ernst.

In that case you have the basic scripts for Metop and NOAA20 in the LEOscripts folder.

Please check and if in doubt, let us know.

did anyone of you make a script for Metop composite? And anything for Noaa19 (single pass or composite)?
