Hi! Sander, you have helped me a lot for working with the SCIAMACHY CH4 data in HARP, thank you so much! Now I have a new problem haha (cries). I was communicating with Mr. Lichtenberg from the German Aerospace Center, he explained to me that the limit values of some parameters (alpha errors) necessary for the correct filtering of the CH4 data are not set correctly in the
flag_vcd_flags field within the files. This is because the code had to be ready for testing, and the exact limit values were not known at that time.
So he recommends that I filter directly from the
non_linear_fit_param_err field (this contains the alpha errors). Since this field is not ingested by HARP, he recommends that I work directly with CODA. My problem is that I cannot find examples of how to use CODA, I have no idea, and in addition to this I know that geolocation of SCIAMACHY can be complicated, this is something that HARP already solved very well.
My question at this point is, is there a way to filter from that field using CODA and then derive the output to HARP?
