[Wrf-users] WRF output into regular grid

[Jose Augusto Paixão Veiga]

Dear Hein,

Thank you for all explanations and suggestions about the softwares.
Recently, someone suggest me, not in this channel, to use CDO to manipulate
the data and easily building them into  regular-space grid. It was very
easy to do it in CDO.

Thank you again,




José Augusto P. Veiga,
