Deprecation notice for wet_bulb_globe_temperature/2.0

As of 19-05-2026, the dataset wet_bulb_globe_temperature/2.0 has been deprecated. As of 01-08-2026, the dataset will no longer receive updates. You are advised to use the updated dataset wet_bulb_globe_temperature/3.0.

The wet_bulb_globe_temperature/3.0 uses a new method to determine the factor of direct sunlight which is used to calculate the WBGT. The calculated WBGT values can therefore be different when compared to the deprecated wet_bulb_globe_temperature/2.0. Furthermore, a new column named ‘heat_force’ was added to the CSV files which is a 0 - 10 index conversion of the WBGT.

Because of these minimal changes, we expect most users should be able to switch to the new dataset by only changing your endpoint from wet_bulb_globe_temperature/2.0 to wet_bulb_globe_temperature/3.0.
