[gradsusr] d tmp.1 - t.2 ' in grads 2.0

[Rupesh Patil]

Dear 
sir,
                   I have attached g1.ctl and temp.ctl .please 
find it .

Actually the resolution of model output of temperature 
 is nearly  equal to  .7degree x .7 degree ( ~ 80km ) .but i can 
convert  it  into 1degree x degree by using re2 function in grads.so i 
have written model output is in 1 degree x 1 degree in previous mail.. 

Regards,
Rupesh

Dear Rupesh,

Could you please send me your ctl
 files, temp.ctl and g1.ctl? I think I have an idea about what's 
happening, but having your ctl files will make it easier to figure it 
out.

Also, please do not send inquiries like this to individual 
people, please send them to the gradsusr list (gradsusr at gradsusr.org).

Best
 regards,

Dear
 sir , 
I got a problem.please read following sentences, 



ga
 -> D:/temp.ctl ! now i open IMD's 1degree x degree data 
having 
variable 'tmp' but data is available only over the Indian region ! 

ga
 -> open D:/g1.ctl ! I open description file of model data having 
variable ' t' 
and resolution 1 degree X 1 degree .this is global 
data ! 

I am able to open these data independently eg. 

ga
 ->d tmp.1 

ga ->d t.2 


but , 

ga -> d
 tmp.1 - t.2 



! operation error : Incomparable grids. 
dimension
 ranges aren't equivalent
 
Dimension =0....................... 
! 
this error comes when
 i use ' ga -> d tmp.1 - t.2 ' in grads 2.0 

please help me. 


Regards,
 
Rupesh.
