Hi Bamba Sylla,
         I am working for your suggestion   *d sum(tpr,t=1,t=240)* and
 found for model and observed data are* 2983* mm and* 897* mm for the *same
Grid and same time*..

*Observed Works....*

 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).
