Climate Data Operators

about CDO

The Climate data operators (CDO) software is a large collection of operators to analyse and process climate and NWP model data. CDO was developed by Max-Planck-Institut für Meteorologie and is part of the „European Network for Earth System Modelling“ as a free package under GPL terms. CDO has the same set of processing functions for GRIB and NetCDF datasets in one package. Moreover, the Climate Data Interface [CDI] can be used for file format independent access. The local MPI-MET data formats SERVICE, EXTRA and IEG are also supported.

The main CDO features

• More than 700 operators available
• Modular design and easily extendable with new operators
• Very simple UNIX command line interface
• A dataset can be processed by several operators, without storing the interim results in files
• Most operators handle datasets with missing values
• Fast processing of large datasets
• Support of many different grid types
• Tested on many UNIX/Linux systems, Cygwin, and MacOS-X
