<div>so, where is the error in file i am not getting it, that is it display the variable for only time t=1, not for the other time,</div>

<br>There's potentially quite a lot of information that you need to provide, but the following at least would be useful:<br>* the script or commands that you used to perform the fwrite, and what GrADS output to the screen when you did this<br>
* the ctl file you created for the output<br>* the results of the command "ncdump -h taux97-98.cdf" (if you have the ncdump utility)<br><br>In the meantime, is it possible that you only wrote out 1 time of the netCDF file? How big is the file tauxobs.grd (e.g. ls -l in Unix)? If the grid is of size nx*ny points, one year of monthly data should give a file of size nx*ny*12*4 bytes. If your file is smaller, you haven't written all times, so repeat the fwrite stage after 'set t 1 12' (or whatever is appropriate). Try this first!<br>
