Daily Max Simplified Wet-Bulb Globe Temperature and its Climate Networks for Teleconnection Study, 1940-2022

This dataset comprises global simplified Wet-Bulb Globe Temperature (sWBGT) values from 1940 to 2022, calculated at a daily maximum with a spatial resolution of 2°x2°. The sWBGT integrates air temperature, dew point temperature, and surface air pressure to provide a measure of heat stress. The dataset was derived from the ERA5 hourly data on single levels.
In addition to the sWBGT values, the dataset includes climate network data and network metrics calculated for selected years (every five years from 1940 through 2020). These data facilitate the analysis of teleconnections, or long-distance correlations in heat stress events, and provide insights into the spatial correlations and propagation of heat stress effects across different regions.
The sWBGT data are stored in NetCDF format, making them compatible with commonly used data analysis tools in climate research. The climate network data and network metrics are saved in the pickle format to ensure efficient serialization and deserialization of Python objects used in network analysis.
All the Python scripts required to calculate the dataset are also included. These scripts allow users to replicate the dataset or adapt the methodology for their own research needs.
This dataset supports researchers in climate science, public health, and environmental policy by enabling the examination of historical trends and the assessment of future risks associated with heat stress.
