climdex 30012013 smallThe CLIMDEX Project aims to produce a suite of in situ and gridded land-based global datasets of indices representing the more extreme aspects of climate. Indices are derived from daily temperature and precipitation data using the definitions recommended by the CCl/CLIVAR/JCOMM Expert Team on Climate Change Detection and Indices (ETCCDI). The project also aims to develop software tools to allow users to access the resulting datasets via a Web interface.
