[gradsusr] Query Reg the computation of Mean Rainfall forecast.

[Geeta Geeta]

Dear all, 
I want to compute the Mean Rainfall Forecast (for Day 1 and day 2) for a month. I have WRF output (separete 30files for each day) for 30 days. 

So I am extracting day 1 ---- Day N Rainfall forecasts (using fwrite) and I have correspondingly the 30 data and ctl files (for Day 1 Forecast). 

Part of the gs file looks like this:   
'reinit'
'open /store/store_output/08june2000/wrf-outp_d01.ctl'
'define r1f8=rainc(t=4)+rainnc(t=4)'
'define r2f8=rainc(t=28)+rainnc(t=28)'
'set fwrite rain24.dat'
'set gxout fwrite'
'd r2f8-r1f8'

*********************
'open /store/store_output/11june2009/wrf-outp_d01.ctl'
'define r1f11=rainc(t=4)+rainnc(t=4)'
'define r2f11=rainc(t=28)+rainnc(t=28)'
'set fwrite rain24.dat'
'set gxout fwrite'
'd r2f11-r1f11'
'disable fwrite'
*********************


But Grads is writing only the last Record to the file  rain24.dat. The output Figures for the 2 days is the Same. 


Pls Suggest HOW CAN I write all the 30 days output to ONE file. 

Thanks 
 
geeta
