How to compile and run?
-----------------------

- In WRFDA directory, type 'configure wrfda - this will create a configure.wrf
  file that has appropriate compile options for the supported computers.

  Note: WRF-Var requires netCDF, BLAS, LAPACK, BUFR libraries. If your WRF-Var package include 
        radiance assimilation capability, the CRTM and RTTOV are needed. 
        If your netCDF library is installed in some odd directory
        , set environment variable NETCDF before you type
        'configure wrfda'. For example, 

        setenv NETCDF /usr/local/netcdf-pgi
        setenv BLAS /usr/local/blas
        setenv LAPACK /usr/local/lapack
        setenv BUFR /usr/local/bufr

        setenv CRTM /usr/local/lapack
        setenv RTTOV /usr/local/bufr

- Type 'compile all_wrfvar' when your ae ready:

- If sucessful, this will create da_wrfvar.exe and a set of utilities
  in directory var/da/.
