The ERA5-HEAT dataset offers an extensive historical reconstruction of indices that represent human thermal stress and discomfort in outdoor conditions. This state-of-the-art bioclimatology data record includes two main variables: the Mean Radiant Temperature (MRT) and the Universal Thermal Climate Index (UTCI). These indices are crucial in understanding how the human body responds to atmospheric conditions like air temperature, humidity, ventilation, and radiation.

The data, derived from the ERA5 reanalysis by the European Centre for Medium-Range Forecasts (ECMWF), merges model data with global observations. This combination provides a comprehensive and consistent description of the Earth’s climate from January 1940 to nearly real-time, with regular extensions as new ERA5 data become available. The dataset's global coverage (excluding Antarctica) and hourly temporal resolution make it an invaluable resource for researchers in climatology, urban planning, and public health.

Heatwaves: Thermal Comfort Indices from ERA5 Reanalysis Dataset

Overview

Heatwaves are a significant climate risk characterized by prolonged periods of excessively hot weather, which can be detrimental to human health and comfort. The ERA5-HEAT dataset provides essential insights into thermal comfort indices that quantify human thermal stress during such events. This dataset is instrumental for research and planning in climatology, urban development, and public health initiatives.

ERA5-HEAT: Human Thermal Comfort Analysis

Analysis

The ERA5-HEAT dataset comprises an extensive historical reconstruction of Mean Radiant Temperature (MRT) and the Universal Thermal Climate Index (UTCI), which are pivotal in assessing human thermal stress and discomfort in outdoor environments.[1] Derived from the ERA5 reanalysis by the European Centre for Medium-Range Weather Forecasts (ECMWF), it merges model data with observations to offer a consistent global climate profile from January 1940 to the present.

Visualizations

Visual representations of the data illustrate the geographic distribution of thermal comfort levels across the globe and historical changes over time.
