Fig. 8. Probability Mass Function (PMF) of daily mean temperature (℃) and temporal evolution of annual outdoor days derived from CMIP6 models. a) The PMFs are generated for two groups of countries – developing countries (Brazil, Nigeria, and India) and developed countries (the United States, the EU, and Russia) – for each GHG scenario: historical (black) and SSP5-8.5 (blue). The bin interval is 1 ℃. The vertical dashed red line in a) indicates the range of temperature (from 10 ℃ to 25 ℃), defined in this study for outdoor days. The background image in a) was obtained from NASA Visible Earth. b) Time series of annual outdoor days (day) derived from 29 CMIP6 GCMs under the historical and SSP5-8.5 scenarios. Thick solid blue line in b) indicates an ensemble mean of CMIP6 models. Horizontal black and blue lines denote the 1976-2005 mean and the 2071-2100 mean, respectively. Difference (2071–2100 minus 1976–2005) in the number of outdoor days is represented in each plot.
