Long term global mean, max, min and range values for wind, solar radiation and water vapor pressure
收藏资源简介：
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: alexis.gkantiragas@gmail.comReferencesFick, S.E. and Hijmans, R.J., 2017.

世界气候数据集（Worldclim）是目前应用最为广泛的长期生物气候数据集，涵盖气候建模、物种分布建模等诸多研究场景中常用的关键生物气候变量的长期平均值（Fick等，2017）。然而，与基于气温和降水的变量不同，风速、太阳辐射与水汽压仅提供月度平均值，而非年度平均值，这限制了其应用场景。 本研究借助QGIS（版本3.40.5-Bratislava）的栅格单元统计函数，计算了各栅格单元内风速、水汽压与太阳辐射的均值、最大值及最小值。本数据集与Worldclim保持一致的空间分辨率，提供10角分、5角分、2.5角分及30秒四种规格的数据，存储格式为GeoTIFF文件，按需可便捷转换为ASCII格式（例如用于MaxEnt图形用户界面）（Gkantiragas，2025）。每个文件均附带栅格计算日志，可用于验证文件生成的正确性。 本数据集包含三个压缩包，分别对应风速、太阳辐射与水汽压数据；每个压缩包均囊括全部四种分辨率的数据集。 若对本数据集存在任何疑问或问题，请联系：alexis.gkantiragas@gmail.com 参考文献 Fick SE, Hijmans RJ. 2017.
