Description

Temperature estimation at each grid point as a function of temperature, temperature lapse rate and elevation for a reference station. Further optional input is the Leaf Area Index (LAI) and the short-wave radiation ratio, which relates the irradiance including terrain effects to that calculated for a flat, horizontal plane. See Wilson & Gallant (2000) for more details.
