[RegCNET] Echam5 projections and downscaling

[turuncu at be.itu.edu.tr]

Hi,

First of all you need to convert ECHAM5 data to netcdf format using CDO
(Climate Data Operator) and NCO (Netcdf Common Operator) softwares
(scripts can be found in util directory, but you need to modift it for
your specific study). After converting grib to netcdf you can read data
from RegCM3 without any problem.

In your specific problem, if the variable names is same with echam5 and
format also same (grib), it could be run for ECHAM4. I only test it for
ECHAM5. If you faced with any problem, please let me know.

ps: i suggest that it could be better to split ECHAM5 files year by year
using CDO before converting netcdf.

best regards
