[RegCNET] Initializing RegCM with ECHAM5 data

[Ufuk Utku Turuncoglu]

Hi,

1 - Yes, it is latest version of the patch. When you are applying the 
patch, there could be some problem related with the version of RegCM3. 
The version of the RegCM3 that is used to create patch may not match 
with the current version. In that case you could modify the RegCM3 based 
on the contents of the diff files.

2 - The files is in same structure when i used this tool. The shell 
scripts must be used to generate annual netcdf files from grib ones. It 
basically use the CDO and NCO tools to process the files and you have to 
install these tools. In my case the data and shell scripts are stored in 
following directory structure,

ECHAM/
               20C/
               A2/
               B1/
               UTIL/

and UTIL directory contains the shell scripts (see attachment). To 
process files, you have to split grib files into annual ones. To do that 
you can use attached split.sh script. Please follow the instructions;

1 - use gendat.sh to create annual grib files. Comment out required 
scenario part that contains the lower and upper limits of the year. Such 
as the lines start with,

# 20C ECHAM
#arr1[1960]=1 arr2[1960]=1464
#arr1[1961]=1465 arr2[1961]=2924

This list can be changed by input dataset and you can create yours by 
using genarray.sh. Please note that, these scripts are not generic ones 
and you may have to modify them.

2 - use gendat2.sh to create RegCM3 netcdf input. These files must be 
placed under DATA directory.

Best regards and good luck,
