A DEM derivative that influences multiple hydrologic processes as well as heat loading factors. A surface representing the downhill slope was created by calculating maximum rate of change between a cell and its neighbors. The final surface has values where higher values represent northerly facing slopes to lower values representing southerly facing slopes where greater heat loading occurs in the northern hemisphere. Further definition comes from ESRI ArcMap help: Incoming solar radiation (insolation) originates from the sun; changes as it travels through the atmosphere; modified by topography and surface features; and is intercepted at the earth's surface as direct, diffuse, and reflected components. Direct radiation is intercepted unimpeded in a direct line from the sun. Diffuse radiation is scattered by atmospheric constituents, such as clouds and dust. Reflected radiation is reflected from surface features. The sum of the direct, diffuse, and reflected radiation is called total or global solar radiation.

Purpose: The purpose of the solar dataset is to weigh the CETWI model based on the amount of solar radiation a hillslope receives throughout an average day. This dataset has high values for shaded hillslope and low values for expose high sun angle hillslopes.
