RE: [ferret_users] Rainfall Summaries

Dear Simon,

In ferret, this is basically regridding again, this time to a monthly axis for example.

You need to define a monthly axis and then you can regrid onto that monthly axis using one of the operators, e.g. @sum.

There are some examples in the user manual.

You can save the regridded variables in a netcdf file with the “save” command.

For tasks like those nco might be faster and even easier.

‘hope this helps,

Best wishes,

Subject: [ferret_users] Rainfall Summaries


Dear all,
I have a daily rainfall dataset on .25x.25 grid for about 100 years.

I would like to do the following at each grid points:

1. Calculate monthly totals of each year and create a netcdf file

2. Create seasonal totals (sum of groups of months) and create a netcdf file

3. Create annual total and store in a netcdf file.

Kindly help me.
