The climate extremes indices defined by the Expert Team on Climate Change Detection and Indices (ETCCDI) are computed for a number of global climate models participating in the Coupled Model Intercomparison Project Phase 3 (CMIP3) and Phase 5 (CMIP5), and reanalyses. The definitions of the indices are given here. The validation of climate extremes indices and analysis of their projected future changes simulated by the CMIP5 models is presented in Sillmann et al. (2013a, 2013b) (see References below).
The indices are available for download from an anonymous ftp server. The URL address will be sent to you by email. Please make sure that you enter your valid email address. If you are already registered, you will be automatically redirected to the ftp server.
