Seviri L2 BUFR reader fails to read RSS Regional Instability Index and Atmospheric Motion Vectors

[jacobbieker]

Describe the bug When loading a scene, giving SEVIRI BUFR filenames should work with the seviri_l2_bufr loader. Instead, it returns that it does not know how to load Regional Instability Index and Atmospheric Motion Vector BUFR files.

To Reproduce

from satpy import Scene
filenames = {}
filenames["seviri_l2_bufr"] = ["MSG3-SEVI-MSGRIIE-0101-0101-20200103134000.000000000Z-20200103134553-4732122.bfr", "MSG3-SEVI-MSGAMVE-0100-0100-20200101181500.000000000Z-20200101182035-4732126.bfr"]
scene = Scene(filenames=filenames)

Expected behavior The BUFR files are loaded and can be interacted with, the same as the cloud mask product or other seviri files.

Actual results Text output of actual results or error messages including full tracebacks if applicable.

From poking around, it seems that possibly the Regional Instability Index files could be added with just a change to here? https://github.com/sfinkens/satpy/blob/e62eb9d60add9e5c1bb4ee1074bf189b5dcd099b/satpy/etc/readers/seviri_l2_bufr.yaml#L29-L34

Hi @jacobbieker , thanks for reporting this issue. Let me ping the people who know about this stuff, they will probably have better answers than me.

Hi @jacobbieker . The reader hasnt been configured to read AMV Bufr and RII products yet. Our AMV product specialist has been looking into this already RII we can have a look at.

Okay, thanks!

Hi!

Is there an update how to read AMV with satpy?
