[gradsusr] Station data error

[Lee Byerle]

Hi, Mehwish,
I have a few suggestions.  In each of your 5 control (ctl) files, make the tdef line the same in all cases, even though the times may be different in the binary data.  This will avoid time dimension errors, e.g.:

TDEF 61 LINEAR 00Z01June2010 6hr

Second, you can keep the time for the gridded file the same for each display, for example:

'd oacres(rain.5(t=1), rain.1)'
'd oacres(rain.5(t=1),rain.2)'
'd oacres(rain.5(t=1),rain.3)'
etc.

Best Wishes,
Lee

I prepared station data files for each month (June-Sep) using station observation data and  then  interpolate with CPC precipitation data using oacres function. It gives me nice view of station precipitation but when i tried to sum up all the summer months station data and interpolate with CPC precipitation data it gives Define error
