Re: [ferret_users] ascii to netcdf

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi,
Paulo mentions reading ascii data where the location information describes a grid. There's an FAQ which discusses that:

Dear Nitin,

Yes, it's possible.

First, you read the ASCII file using the "file" command

http://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/data-set-basics/ASCII-DATA

You can optionally set variable attributes with "set variable"

http://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/commands-reference/SET#_VPINDEXENTRY_1754

Then you write to a netCDF file using the command "save"

http://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/commands-reference/SAVE

If your ASCII data is actually a gridded variable you are allowed to specify that grid in the "read" command after you defined the grid with "define axis" and "define grid" commands.

Dear ferret users,

I have a 3 column format ascii file (attached) which includes lat, lon, data values. Is it possible to convert it to netcdf using ferret?

Any idea kindly let me know.

Thanks
