Area-extent of temperature and precipitation extremes in CMIP5 models under different radiative forcing scenarios, observations and reanalysis

The EmCEI is a combined temperature and precipitation extremes index, measuring the percentage area experiencing "extreme conditions" across five components. "Extreme conditions" is defined as above the 90th percentile or below the 10th percentile. The five components are maximum temperature, minimum temperature, total annual precipitation, heavy precipitation and wet and dry days. These components are calculated from the so-called "ETCCDI indices".Each individual component is made of two sub-components, corresponding to upper and lower tail extremes respectively. Here, the EmCEI components are calculated for 8 CMIP5 models under the historical, historicalNat and historicalGHG scenarios over the period 1951-2005. The same components are also calculated for the ERA-20C reanalysis and an observational data product (GHCNDEX extended with HadEX2).
