Description
Forty years of daily SnowModel simulation outputs from September 1980 to August 2020, covering the Core ABoVE Domain at a 3-km grid resolution. The dataset includes 15 variables such as air temperature, snow-water-equivalent depth, snow density, and runoff, generated by NASA using a model that integrates land cover, topography, ground observations, remote sensing, and meteorological reanalysis data. Data are provided in NetCDF format.
Use Cases
Analyzing long-term trends in snow-water-equivalent (SWE) depth and snow density for climate impact studies.
Modeling hydrological runoff and snow melt processes using the provided daily precipitation, melt, and runoff columns.
Studying snow-atmosphere interactions through variables like air temperature, surface temperature, wind speed, and snow sublimation.
Validating remote sensing snow products or other snow models against this simulated dataset for the ABoVE region.
Investigating snowpack thermal properties using the bulk snowpack thermal resistance and snow depth variables.
Strengths
Covers a 40-year time period (1980-2020), providing a long baseline for trend analysis.
Integrates multiple data sources including ground observations, satellite data, and reanalysis for model forcing.
Provides a specific 3-km spatial resolution over the defined Core ABoVE Domain.
Includes 15 distinct physical variables related to snow, meteorology, and surface processes.
Limitations
The exact row count and dataset size are not specified across any platform.
