I want to assimilate ZWD or PW (I have both) data into WRF model, but I did not find nothing helpful. There is a WRFDA for 3DVAR tutorial, but I can not understand, what exactly should I do with my data and how to run WRF after data assimilation. I have a lat-lon grid of PW/ZWD. Can anyone, please, explain me, what should I do for data assimilation? Or just leave a link to the detailed tutorial...
P.S. I've found that I should create my own observation files to run them with 3DVAR, but there is no instruction, how to create them.
