[RegCNET]Re: Analysing RegCM output in arcview: Extracting climate estimates on irregular grids in arcview

[Gil Lizcano]

Hello Joseph,

I can provide you some scripts to convert netcdf to ascii arcview format. 
They  are based on awk and nco. 
Otherwise, I have another script to do the conversion using octave/matlab.

If you are familiar with these languages and have installed nco or octave 
in your system,  let me know and I will send you  the scripts.
