<b>Long term global mean, max, min and range values for wind, solar radiation and water vapor pressure</b>

The Worldclim dataset is the most widely used set of long term bioclimatic data, with long term averages for key bioclimatic variables used in climate modelling, species distribution modelling and countless other applications (Fick et al., 2017). However, unlike temperature and precipitation based values, wind, solar radiation and water vapor pressure are provided as monthly, rather than annual averages.This limits their use cases. Here, I used QGIS (ver 3.40.5-Bratislava) cell statistic function to calculate mean, maximum and minimum per cell values for wind speed, water vapor pressure and solar radiation. These are provided at 10min, 5min, 2.5min and 30 second resolution as in the Worldclim dataset. These are provided as geotiff files, but can be readily converted into ASCII if required (such as for Maxents GUI) (Gkantiragas, 2025). Each file has an accompanying log for the raster calculation and can be used to check that the file was correctly generated.There are three zip folders, one for wind, solar radiation and water vapor pressure. Each zip folder contains the data at all 4 resolutions. For questions or issues with the dataset please address them to: [email protected]
