Fig. 3: Percentage of days with a release of heat from soil into the atmosphere in summer.
From: Soil heat extremes can outpace air temperature extremes
a, Percentage of days with maximum soil temperatures (TSoil) higher than maximum air temperatures (TAir) during air hot extremes as represented by the multimodel mean of the CMIP6 models under the 1.5 °C warming level and its difference with warming levels of 2.0 °C and 3.0 °C. Air hot extremes are defined on the basis of the TX90p index. b,c, Averaged percentage of days with TSoil > TAir over central-western (b) and central-eastern (c) Europe (see rectangles in a) from 1990 to 2100 for each model separately.
