CDO - Climate Data Operators
----------------------------
This package contains the source code for CDO. This program
was developed at the Max-Planck-Institute for Meteorology.
CDO is a collection of Operators to manipulate and analyse
Climate model Data.
Supported data formats are GRIB, netCDF, SERVICE, EXTRA and IEG.
CDO is licensed under the GNU General Public License, version 2.
Read the file COPYING in the source distribution for details.
Operators:
There are more than 400 operators available. Read OPEATORS for
a short overview of all operators.
Documentation:
A detailed description of all operators can be found in: ./doc/cdo.pdf
Online reference manuals: cdo -h <operator>
Building and installing it:
1. Run ./configure, with some options if you wish. The standard
options are documented in the INSTALL file. The configuration
script has some more options; type 'configure -h' to see them.
--prefix=<installation directory> and
--with-netcdf=<directory> to enable netCDF support.
The netCDF-4 configuration depends on the netCDF-4 and HDF5 installation!
You have to define the location of the HDF5 installation if netCDF-4 was
build with HDF5 support:
--with-netcdf=<netCDF-4 root directory> --with-hdf5=<HDF5 root directory>
You have to specify also the location of the SZLIB if HDF5 was build with
SZLIB support.
To process szip compressed GRIB files you have to enable SZLIB support with:
--with-szlib=<directory>
2. Do "make" to compile the program.
3. (Optional) Do "make install", possibly as root if the destination
permissions require that. This installs CDO in the directory
specified during configuration. The default prefix is /usr/local.
Porting:
This package was designed for maximum portability. It is written entirely
in ANSI C99, and will compile on most UNIX platforms.
