Inquiry about FY-3D/E/F Satellite MWHS and MWTS Sensor Coefficient Files

[Cuijiawen971221]

Dear Dr./Mr. Benjamin Johnson

I hope this message finds you well.
I am writing to inquire about the availability of coefficient files for the Microwave Humidity Sounder (MWHS) and Microwave Temperature Sounder (MWTS) sensors onboard the FY-3D, FY-3E, and FY-3F satellites.
Currently, I am working on a project related to satellite data assimilation and radiative transfer modeling, which requires accurate sensor-specific coefficients (e.g., SpcCoeff, TauCoeff, or similar files) for these instruments. While I have been able to generate some coefficient files using available tools (such as CRTM coefficient generation utilities), I have encountered challenges with certain datasets or configurations.
If you have already generated or maintain official coefficient files for the FY-3D/E/F MWHS and MWTS sensors, I would be grateful if you could share them or provide guidance on how to access them. Alternatively, if there are recommended methodologies or validated workflows for generating these coefficients, I would appreciate any advice or references you could offer.
Thank you for your time and assistance. I look forward to your response.

Best regards,
