Snowpack (Forced by Gridded Observed Data)
Snow Water Equivalent (SWE) is a common snowpack measurement. It is defined as the amount of water contained within the snowpack. These snowpack projections are produced by using a land surface/hydrology model known as the Variable Infiltration Capacity (VIC) model. The VIC model uses a gridded dataset of observed precipitation and temperature data as input to calculate SWE and a suite of additional parameters. Details are described in Livneh et al., 2015.
Spatial Resolution and Extent
The spatial resolution of this data is 1/16º (approximately 6 km). The spatial extent available on Cal-Adapt covers entire state of California and Nevada and parts of Oregon, Mexico and Arizona.
- Data is available over the period 1950–2013.
For large areas or full spatial extent, it is more efficient to download data in NetCDF or GeoTIFF formats and clip to desired spatial extent. For smaller areas, additional options for downloading data in CSV or JSON formats are available through download tool below.
