[gradsusr] RMSE for magnitude of wind

[shimelis berhanu]

Dear all,


My knowledge on Fortran is very poor. Therefore, here I am looking for your kind help for 
Fortran code to read rainfall data from  CMORPH Version 1.0 BETA Version. I have daily
data from 2000 to 2007 (eg. the file has a name CHOMPS.dy.2000.dat,...). May someone has 
a Fortran code to read such a data?


Kind regards,

Lyndon,
Here is an example for the wind field rmse, with u and v wind as variables in the model files.

open file1.ctl
open file2.ctl
 
define diffu=u-u.2
define diffv=v-v.2

define varu=pow(diffu,2)
define varv=pow(diffv,2)
define rmse=sqrt(varu+varv)
 
display variable rmse

Best wishes,
Lee

Hi all, 
I would like to make a script to find the rmse between a model and a nudged file..I can find the rmse for the U and V component, but how do I make an RMSE for the magnitude of the wind;mag(u,v)?

Thanks a lot,
Lyndon Mark
