Hi Sablone,<br> You can use subwrd function for that. Suppose you want to have data form 2000 to 2009, you can do it as given below. Put a variable yyyy for year such that you can use while loop for time step. This script will write output in the ascii file output.txt as given in the 10th line. The gs file is attached<br>
<br><br>************************************************<br>'reinit'<br>'sdfopen <a href="http://filename.nc">filename.nc</a>'<br>'set lon 90'<br>'set lat 15'<br>yyyy=2000<br>while(yyyy<=2009)<br>
'set time jan'yyyy''<br>'d aave(precip,lon=39,lon=41,lat=-5,lat=0)'<br>te=subwrd(result,4)<br>w=write(output.txt,te)<br>yyyy=yyyy+1<br>endwhile<br><br>***********************************************<br>

<br>
I wish to extract data from gridded netcdf file for a particular domain to<br>
get a time series (i.e of a particular month or season for a number of<br>
years) and write it in ascii file so that I can export the series to say<br>
excell.<br>
<br>
I can do this, but through the long way of using the commands for example:<br>
<br>
'set t 1 30'<br>
'd aave(precip,lon=39,lon=41,lat=-5,lat=0)<br>
<br>
Through this I am unable to only get the targeted months or season of the<br>
years. Furthermore I have to mannualy copy the data from Grads and paste<br>
in excell the rearrange the data to pick the months or seasons I target.<br>
<br>
My question is: How can I extract the data for the targeted months and<br>
directly write them ascii file.<br>
<br>
Thanks<br>
