A New Dataset of Temperature and Precipitation Extremes

HadEX3 is an updated dataset of gridded temperature and precipitation extremes, that covers the period of 1901 to 2018 and has improved spatio-temporal coverage.

Changes in climate extremes can have significant impacts on human society and ecosystems. The HadEX3 dataset describes and uses the newest source of comprehensive observations to quantify the changes of these extremes in daily temperature and precipitation.

Dunn et al. [2020] show that the extremes related to daily minimum temperatures are changing faster than the maximum, all of which are consistent with widespread global warming. Spatial changes in the linear trends of precipitation indices over 1951-2018 are less homogeneous than those for temperature indices, but the fraction of precipitation falling in heavy events globally has increased.
