WRFPLUS and WRF4DVAR need to be compiled in two different directories.

Re: WRFDA for nested domains

You are right that WRFDA does not support nested run and you have to run WRFDA separately for different domains.
So for 4DVAR, you need to create a wrfbdy file for each domain you want to analyze.

Re: How to use GOES radiance data?

use_goesimgobs=true. Those are NOAA GVAR NC file named: goes-13-imager.nc, goes-14-imager.nc, or goes-15-imager.nc

Re: WRFDA compilation problem (Can't open module file 'da_module_domain.mod' )

Did you compile WRFDA in a separate directory. WRFDA and WRFPlus need to be compiled in the separate directory even though all source code is now included under the same tar file.

Re: WRFPLUS V3.9 compile problem ( no rule to make target ‘wrfplus’)

'./compile wrfplus' is from WRF V4.0. Please check V3.9's users guide for wrfplus compilation.

Re: ERROR with CRTM_K_Matrix

This looks like related to your use of 21-class MODIS Landuse.
WRFDA may need some code update to use it. Did you try the older one like USGS?

Re: assimilate surface observations from MESOWEST

WRFDA can assimilate conventional obs either in ob.ascii format (produced by OBPROC program with little_r data input)
or NCEP PrepBufr format. You need to convert your data inth one of two formats.

Re: How to prepare a set of ensembles with RANDOMCV

Check Users Guide chapter: http://www2.mmm.ucar.edu/wrf/users/docs ... les_with_1

When running WRFDA for different members, modify seed_array1 and/or seed_array2

Re: latent heat nudging (LHN) using 3DVAR

Any nudging is done through model integration, not in 3DVAR.

Re: WRFDA 4.0.0 compile error ;error #7002: Error in opening the compiled module file. Check INCLUDE paths.

if you search 'Error' in your compile log file, you will find 'ld: cannot find -lhdf5_fortran'. Looks like you own compiled HDF lib may not be successful. check 'include' directory under your hdf path as well.

Re: Will RTTOV 122 be supported by WRFDA?

RTTOV12 will be supported from version 4.1. If you check out the WRF code from the latest WRF github repository, you can already use RTTOV12 with WRFDA. Jake.
