Solar Calc: Estimating Hourly Incoming Solar Radiation from Limited Meteorological DataEntry ID: USDA_ARS_SolarCalc
Abstract: Two major properties which determine weed seed germination are soil temperature and moisture content. Incident radiation is the primary variable controlling energy input to the soil system and thereby influences both moisture and temperature profiles. However, a majority of agricultural field sites lack proper instrumentation to measure solar radiation directly. To overcome this shortcoming, an empirical model was developed to estimate total incident solar radiation (beam and diffuse) with hourly time steps.
