WorldClim 2.1 Atmosphere Variables (0.5 arc-minute resolution, bimonthly composites): Global solar radiation, wind speed, and vapor pressure

This dataset provides bimonthly composites of atmospheric variables from WorldClim 2.1 at 0.5 arc-minute (~1 km) spatial resolution, including solar radiation (srad), wind speed (wind), and water vapor pressure (vapr). Monthly WorldClim rasters were aggregated into bimonthly means to reduce redundancy and improve computational efficiency in ecological and environmental analyses. GeoTIFF (.tif) rasters contain six bimonthly layers. Variables included: srad: Mean solar radiation (kJ m⁻² day⁻¹) wind: Mean wind speed (m s⁻¹) vapr: Mean water vapor pressure (kPa) Data source: WorldClim v2.1 global climate database (Fick & Hijmans, 2017)Temporal aggregation: Bimonthly averages from monthly layers (Jan–Feb, Mar–Apr, …, Nov–Dec)Spatial resolution: 0.5 arc-minute (~1 km)Coordinate reference system: WGS84 (EPSG:4326) Citation:Fick, S.E. & Hijmans, R.J.
