Have a nice day! Everyone. I have one question/problem:
I found that, after assimilation, the values of 10-m wind variable are unchanged. For example, I assimilated (using 3DVAR method, WRFDA 4.2 version) the data to update wrfinput_d02 file, then I get an updated wrfinput_d02 file. I found the values of 10-m wind speed in original wrfinput_d02 and new wrfinput_02 are the same. However, other variables, such as the values of U and V wind components at different pressure levels, have been changed.
This means that the diagnostic variable 10-m wind speed has not been changed after assimilation. How can I investigate the assimilation impact on 10-m wind background field?
Thank you all very much.
