:description = "The ClimAVA-SWE dataset provides high-resolution (4 km) bias-corrected, downscaled future climate projections based on 14 CMIP6 GCMs. The dataset includes the snow water equivalent (SWE) variable and three Shared Socioeconomic Pathways (SSP245, SSP370, SSP585) for the western United States. ClimAVA-SWE employs the Spatial Pattern Interaction Downscaling (SPID) method, which uses Random Forest models to capture relationships and interactions between coarse-resolution spatial patterns and fine-resolution pixel values. Two Random Forest models are trained per pixel—one for the accumulation period and one for the melting period—using high-resolution reference data as targets and nine neighboring pixels from spatially resampled (coarser) versions as predictors. These trained models are then applied to downscale the GCM data. For more details, refer to the publication describing the method and dataset." ;
