correct syntax of remapnn in CDO ruby gem

Added by jay qiu over 9 years ago

Hi,

I would like to ask the correct way to use "remapnn" operator in ruby.

Actually my purpose is to select a specific grid point from my nc file

Thanks.

Jay

Just an example from the first like page

Cdo.remapnn('lon=-68_lat=-18', :input => ifile, :output => ofile)

With this, you compute a single horizontal value per timestep. If you want to get it as a NArray, just add returnArray='t' if the variable name is 't':

t_values = Cdo.remapnn('lon=-68_lat=-18', :input => ifile, :output => ofile, :returnArray => 't')
