Future hydrologic outputs using the Distributed Hydrology Soil Vegetation Model (DHSVM) for the Saddle Catchment, 2001 - 2100.

The Saddle Catchment of the Niwot Ridge LTER is subject to warming in
a future climate and thus changes in precipitation phase,
precipitation redistribution, and timing and distribution of surface
water inputs (the summation of rainfall and snowmelt) as well as
changes in atmospheric demand (potential evapotranspiration, PET) and
the amount of evapotranspiration (ET). The input warming data were
developed to first force a future climate across the Saddle Catchment
and evaluate resultant hydrologic outputs using the Distributed
Hydrology Soil Vegetation Model (DHSVM). Future forcing data were
generated by calculating and implementing delta values between daily
average historical data and those generated from
end-of-current-century Weather Research Forecasting model data. The
variables perturbed in the warming DHSVM simulation were:
precipitation, air temperature, relative humidity and longwave
radiation. Target outputs included: daily spatially distributed
precipitation (historical and future), daily spatially distributed
surface water inputs (historical and future), total spatially
distributed PET (historical and future), and total spatially
distributed ET (historical and future). The precipitation and surface
water inputs products are orthorectified (UTM projection) raster
products, and the forcing data and PET and ET are CSV files. The
forcing data represent catchment averages, which are distributed
within DHSVM, and all other files are at the 2 m resolution.
