No RSR data for Metop/AVHRR #42

Closed pnuu closed 6 years ago

pnuu commented 6 years ago

Problem description

There is no RSR data available for Metop/AVHRR. Or at least they are not defined in the built-in configuration file.

adybbroe commented 6 years ago

In the RSR data that downloads automatically from Zenodo we have two files:

rsr_avhrr3_Metop-B.h5
rsr_avhrr3_Metop-A.h5

I have currently forgotten where I got the original response data. But they should not be needed!

pnuu commented 6 years ago

Oh, the config doesn't manage the RSRs already in the HDF5 files? Ok, I thought that all the files should be configured there so they are actually found by PySpectral.

adybbroe commented 6 years ago

No, exactly, the many satellite/platform specific entries in the config file is only for the case where you want to read the original response data, which will usually not be needed by the user. So, no worry, if a satellite is not listed there. The important thing is if there is a hdf5 file included in the files downloaded from Zenodo with responses for the platform.

Ah, ok. And by setting rsr_dir and rayleigh_dir in pyspectral.yaml one can set the dir where the RSR and areosol files are stored, right?
