Spatial distribution of snow water equivalent for the Niwot Ridge, 1996 - 2019

This dataset provides a daily estimation of snow water equivalent for
the Niwot Ridge during snow melting period from 1997 to 2019 at
30-meter spatial resolution. The dataset includes two series of SWE
data: 1) 1996-2007 daily SWE dataset is generated by Jepsen et al.,
(2012); 2) 2008-2019 daily SWE dataset is generated by Dr. Kehan Yang
following the same method used by Jepsen et al., (2012). In brief, a
physically based reconstruction model is used to calculate daily SWE
backward from snow disappearance date to peak snow accumulation. The
infilled hourly climate data set for C1, Saddle and D1 (data available
at
https://portal.edirepository.org/nis/mapbrowse?packageid=knb-lter-nwt.168.2)
is interpolated and used as the meteorological forcing in the snow
energy balance calculation of SWE reconstruction. The shortwave
radiation is estimated by downscaling hourly product of the
Geostationary Operational Environmental Satellite (GOES) using TOPORAD
tool. The USGS Landsat Level-3 fractional snow-covered area product is
used to proportion potential energy flux for snowmelt at the pixel
scale. Please see detailed methods included with this data package for
