Hi Rajesh,
If you have some doubts just sum up values for all timesteps and you will have the cumulative rainfall for the month.
d sum(tpr,t=1,t=240)

cheers !

Hello All,
 
      I am plotting the contour for precipitation , in that it is showing 3 hourly data( In SRF file ). Here I am plotting monthly precipitation the command i am using is  
ga-> d ave(tpr,t=1,t=240)*30 (mm) and found the value 542, 479,455,512,513 mm ( year-  2000, 2001,2002, 2003, 2004) but observed data (IMD Delhi, India)  same time and same grid are found 799, 797, 658, 854, 815 mm respectively.
 
again using  Mr. Md. Mizanur Rahman suggestion using command ga-> d ave(tpr,t=1,t=240)*8*30 (mm) and found the values 4340, 3832, 3643, 4099, 4099, 4103 mm respectively.


Please let me know If i am missing something.
 
Thanks

hi rajesh
I think your formula is wrong. Because you are multiplying only by 30, it is not correct. It should be multiplied by 24*30, because you are doing average (t=1, t=240), after averging you will get one hour rainfall after that you will multiply 24 to average rainfall then you will get 24 hours rainfall. i, e complete formula for one month will be ave(t=1, t=240)*24*30 then you will get one month rainfall (mm).

Hello All,
 
      I am plotting the contour for precipitation , in that it is showing 3 hourly data( In SRF file ). Here I am plotting monthly precipitation the command i am using is  ga-> d ave(tpr,t=1,t=240)*30 (mm) My question is about the command whether it is right one to get correct value or else .
 
Please let me know If i am missing something.
