High-resolution spatial modeling of daily weather elements for a catchment in the Oregon Cascade Mountains, United States

摘要: Abstract High-quality, daily meteorological data at high spatial resolution are essential for a variety of hydrologic and ecological modeling applications that support environmental risk assessments decision making. This paper describes the development, application, assessment methods to construct high-resolution (∼50-m cell size) grids 2003 calendar year in Upper South Santiam Watershed (USSW), 500-km2 mountainous catchment draining western slope Oregon Cascade Mountains. Elevations within USSW ranged from 194 1650 m. Meteorological elements modeled were minimum maximum temperature; total precipitation, rainfall, snowfall; solar radiation radiation-adjusted temperature. The Parameter–Elevation Regressions on Independent Slopes Model (PRISM) was used interpolate temperature precipitation. separation precipitation into rainfall snowfall components temperature-based regression...
