[gradsusr] help - NetCDF file

[Matt Masarik]

Hi Celso,

you can solve this by using a small (3 line) control file
that has the 365_day_calendar option specified.  Copy
the following text into a file, say, amazonia.ctl

DSET ^amazonia.clm2.h0.2002-01-04-00000.nc
OPTIONS 365_day_calendar
tdef time 3084 linear 16jan1850 1mo

I put your file name in the DSET line already.  You will
need to change the 3084 to the total number of time
records in the file.  You can find this out by issuing
the following at a command prompt:

ncdump -c amazonia.clm2.h0.2002-01-04-00000.nc

you will also need to change 16jan1850 to the start
date of your data set, again use ncdump.

Once you make those changes you should be able to open
the file by using

xdfopen amazonia.ctl
