Hi Wendi,<br>you have to write a control file for opening netcdf files that don't follow coards convention. The control file should contain description similar to the following script:<br>dset ^./<a href="http://Sagar.clm2.h0.2003-01-01-00000.nc">Sagar.clm2.h0.2003-01-01-00000.nc</a><br>
dtype netcdf<br>options template 365_day_calendar<br>tdef time 365 linear 1JAN2003 1dy<br><br>You have to check the content of netcdf file (such as using ncl) and write the control file accordingly. You have to use 'xdfopen' or simply 'open' to open such control files. Details of xdfopen can be found in grads page.<br>
