NCEP2GFDL

Concatenate NCEP reanalysis files into one GFDL-format netCDF file.

Description

This code fragment concatenates NCEP reanalysis netCDF data files into one big netCDF file that follows GFDL format.

Originally this code fragment was used as a pre-processing step to Climate Diagnostics Suite ( http://sourceforge.net/projects/cds ). After a couple of people have asked me for the pre-processing code I decided to publish it separately because it is quite a nice example of manipulating netCDF files in MATLAB.

Run the file using NCEP2GFDL('Reanalysis.nc') for example. The folder contains NCEP2GFDL.m file, which calls interpolate_data_xlongitude_ylatitude.m file for interpolations. Other .nc files are the files which NCEP2GFDL operates on and should be downloaded by a C-SHell script get_reanalysis.csh. These NCEP files are later cleaned up by cleanup_reanalysis.csh script.

This file is primarily designed to be used as a template/guide and not as a standalone application. The user is free to modify this file any way they wish to fit their custom needs.

• MATLAB release: MATLAB 7.0.1 (R14SP1)
• Other requirements: Requires a netCDF toolbox for Matlab, which is free. This code has been tested on a Pentium 4 E Debian Linux system using Matlab 7 SP1 and SP2 software.
