1.5 degree information

A set of 27 climate extremes indices as defined by the Expert Team on Climate Change Detection and Indices (ETCCDI) is being calculated for the HAPPI simulations for the various experiments and models. The definitions and some applications of these indices can be found in Sillmann et al. (2013a, 2013b). If you are interested in using the ETCCDI extremes indices from the HAPPI simulations, please contact Jana Sillmann (jana.sillmann@cicero.oslo.no) and Nathalie Schaller (nathalie.schaller@cicero.oslo.no).
