[gradsusr] Help - Grads doesn't exibit the result at terminal on stat mode

[Eric Altshuler]

Hello Elias,

You need to define a1 as a grads data variable, not a script variable:

'a1=0'
...
'a1 = a1 + (aave(t2.'f'(t=9),lon=-58,lon=-48,lat=-34,lat=-22) - aave(t2.'f+1'(t=1),lon=-58,lon=-48,lat=-34,lat=-22))' 
...
'd a1'

Hi, my objective with the script above is to obtain a number that is able to show a mean value of an area (an image), my work involves to verify the quality of the forecast produzed by the WRF model. So I calculate the mean value predictioned and subtract with the value observed. The problem is the GrADS calculate everytinhg bus does not show any result, simplely reset. How is possible to see I want the resul at terminal. I really hope the somebody can help me 



***were opened all *.ctl .

'set gxout stat' 


a1=0 


f=1 


while (f<=arq) 


a1 = a1 '+ (aave(t2.'f'(t=9),lon=-58,lon=-48,lat=-34,lat=-22) - aave(t2.'f+1'(t=1),lon=-58,lon=-48,lat=-34,lat=-22))' 


f=f+1 
endwhile 

'd 'a1
