[Wrf-users] numerical postprocessing

[Gil Capote Mastrapa]

hello 
 can anyone recommend me a tool for numerical analisis of WRF output files
?. i already use Calwrf for CALMET-CALPUFF assimilation of WRF output
files, but im not sure if this program modifies the original output
fields. i use Grads also , but mainly for display the results. i need a
solution for numerical analisis.
 hope somebody can help me, 
     best regards ,
         gil.
