Dear Sir/Ma’am,
Hello, this is chaochao. I am currently working on the data assimilation of the FY-3F Microwave Humidity Sounder (MWHS-2). Since the CRTM coefficient files for this instrument are not publicly available, I referred to the CRTM_coef tool you shared in the Git repository and followed the manual to generate the spc and tau files.
However, when running GSI assimilation experiments with these coefficients, I found that the OMB (Observation minus Background) shows a large bias, on the order of several tens of Kelvin. I suspect that there may be an issue with the tau file I generated. Could you kindly provide some guidance or assistance?
For your convenience, the spc and tau files are provided below. I look forward to your reply. Any help or suggestions would be greatly appreciate d.
My email is daoheheo@163.com
The coefficient related documents I made are in https://github.com/daohehe/crtm_coef_tst/releases/tag/v1
Sincerely,
chaochao
