Tropomi l2 reader ValueError: No supported files found #2659

The Tropomi l2 reader can read ’S5P_OFFL_L2NO2__‘ files but cannot read 'S5P_RPRO_L2NO2__' files.

satpy==0.41.1

I'm not familiar with tropomi files. Could you tell me the difference between these two types?

Kexin828 commented 10 months ago

Thanks for your reply.

Tropomi reprocessed data(RPRO) involves applying the latest processing techniques to improve the quality of existing data, while offline data(OFFL) is processed after a certain time lag from the observation time, allowing for careful calibration and validation.

They have basically similar data composition, but I can't read the RPRO data with the same code, and I don't know how to fix this.

Your files have reduced in their names, which means the pattern defined here doesn't match. You could try creating your own local config that has the reduced in it:

create a directory for config files and set environment variable SATPY_CONFIG_PATH=/path/to/your/configs
under that directory, create readers subdirectory
copy the satpy/etc/readers/tropomi_l2.yaml to the subdir
add a new pattern to the pattern list with the reduced added to the end. Now, if the internal file structures match, you should be able to read the files. If this works, please create a pull request with the change.
