[gradsusr] 360 day calendar issue

[Illeana Gomez Leal]

Hi,

I have matrices of T21 space resolution and 2880 points in time (8 points per day in a 360 day year), and I have more that 200 netcdf files of this type.
If I must convert all my data, how does GrADS work? Can I change the string « 360_day » in time:calendar to another value in order to trick it?

Thank you very much,
Illeana

You can write a full control file. I would think all of the necessary information to write a control file would be present. You'll just have to extract it manually. For example, you can use the information from the output from ncdump of the time array variable in your TDEF entry.

Hello all,


I'm working with a researcher with a lot of data based on a 360 day calendar. Example from ncdump:

double time(time) ;
        time:calendar = "360_day" ;
        time:units = "days since 0199-01-01 00:00:00" ;
        time:base_date = 199, 1, 1, 0 ;


I understand that 360 day calendars are no longer supported in grads. We've tried version 2.0.2 and 2.1.a3 and get the "SDF Error: 360 day calendars are not supported by sdfopen" error with both.


What options do we have, if any, short of rerunning the processes?


thanks in advance,

Tom
