This PR is addressing issure #221 to convert the clear sky GOES ABI radiance bufr data to ioda.
Two files have been added to RDASApp/rrfs_test/IODA/python.

@xyzemc Thanks for adding the new converter. Would you like to stage the ABI IODA files in RDAS_DATA?

Yes. Thanks for reminding me.
Please copy the following data from the directory: /scratch2/NCEPDEV/fv3-cam/Xiaoyan.Zhang/noscrub/JEDI/RDASApp_1107/expr/mpas_2024052700/data/obs

Will do! Do you plan to include channel 17?

Do you mean GOES_17?

[SamuelDegelia-NOAA]

Oops, I see those are satellites now. I first read them and thought the files were split by channel. You can ignore this!

The data have been staged on all supported machines.

Just out of my curiosity, are the ABI data provided with a parallax correction applied? Or is that something that we can apply through JEDI filters?

Please remind me what the parallax correction is. The abi data we used in operational is the 16x16 averaged products (CSR), instead of the original pixel data.

[SamuelDegelia-NOAA]

The parallax correction adjusts for location errors due to tall clouds. See here. Since this PR is for clear-sky ABI it should not be relevant, but once we get to all-sky assimilation then we might need to think about it if the data are not already corrected.

That's a good point. Let's think about it when we implement all-sky in the near future.
