Wet Bulb Globe Temperature

WBGT (Wet Bulb Globe Temperature)

1.Hourly Wet-bulb Temperatures (WBT) during the period of 1979-2022 derived from ERA5 reanalysis is available on Zenodo: https://doi.org/10.5281/zenodo.10418938

2.Hourly simplified Wet Bulb Globe Temperatures (WBGT) during the period of 1979-2022 derived from ERA5 reanalysis is available on Zenodo: https://doi.org/10.5281/zenodo.10428575

Variables used to calculate the WBGT are 2-m air temperature (t2m), 2-m dewpoint temperature (d2m) and surface pressure (sp) from the ERA5 reanalysis dataset based on an approach described in “Dawei Li*, Jiacan Yuan*, and Robert E. Kopp (2020): Escalating global exposure to compound heat-humidity extremes with warming. Environmental Research Letters. DOI: 10.1088/1748-9326/ab7d04“. Please cite this article when using this dataset.

3.Here are some data to repeat the results in the work “Dawei Li*, Jiacan Yuan*, and Robert E. Kopp (2020): Escalating global exposure to compound heat-humidity extremes with warming. Environmental Research Letters. DOI: 10.1088/1748-9326/ab7d04“.

Figure 3. Global maps of frequencies of exceedance indexed by ΔGSAT for bias-corrected WBGT*max at 31 ◦C (left column), 33 ◦C (middle), and 35 ◦C (right). Top row is based on an 1800-year CESM simulation under the preindustrial scenario, while the rest are based on the 40-member CESM-LE RCP8.5 simulations. Indexing by ΔGSAT is done by picking years from each simulation with ΔGSAT falling into the ±0.25 ◦C bracket centering at the specific ΔGSAT. The maps are limited to 60◦S-80◦N,130◦W-160◦E since frequencies are all below one day per century over major land areas outside this region.
