no idea how much work this really is. But could you write a SatPy reader for the FengYun GEO satellites (FY2E and FY2G IIRC)? It's HDF5 files in EUMETCast Channel_12 (Z_SATE_C_BABJ_2019 ....HDF.gz). Or could this be sort of a student project that you are able to initiate? Thank you for the code you already gave to Pytroll. My contribution will stay on a far lower level. With my aging brain I already struggle to keep my medium C-knowlege alive ...
