GHWT: Global Heat Wave Toolbox

Using three historical reanalysis data and multi scenario CMIP6 modeled data, Global Heat Wave Toolbox (GHWT) was developed to generate heat wave matrix from 1971 to 2100.

A long-term global heat wave record dataset was constructed using three historical hourly climate data of CRU-JRA, ERA5 and GLDAS and future daily climate data of GFDL-ESM4 under three SSPS (Shared Socioeconomic Pathways). These datasets are based on constant thresholds over 35 °C, percentile thresholds over 90%, and duration thresholds over 3 days. The Python file is the source code for the Global Heat Wave Toolbox, which can be used to generate heat wave records based on custom thresholds.
