Near-global freshwater-specific environmental variables for biodiversity analyses in 1 km resolution [Nature Scientific Data]

Subject terms : Biodiversity, Biogeography, Freshwater ecology, Macroecology

The lack of freshwater-specific environmental information at sufficiently fine spatial grain hampers broad-scale analyses in aquatic biology, biogeography, conservation, and ecology. Here we present a near-global, spatially continuous, and freshwater-specific set of environmental variables in a standardized 1 km grid. We delineate the sub-catchment for each grid cell along the HydroSHEDS river network and summarize the upstream climate, topography, land cover, surface geology and soil to each grid cell using various metrics (average, minimum, maximum, range, sum, inverse distance-weighted average and sum).(...)
