[Wrf-users] Minimal number of variables to run WRF (climate experiments)

[Jose Augusto Paixão Veiga]

Dear Dom and lldan,

thank you very much by shearing this document with me and I sure believe it
will help me with my doubts and put me in the hight direction to choosing
the correct variables to run WRF.

Thank you guys a lot.
