<p> A simple model, expressed in terms of cloud amounts and heights, and air temperature (recorded hourly at Ft. St. John, B.C.) and daily radiosonde records (from St. Nelson, B.C.), is used in an attempt to approximate incoming solar and net radiation values at a nearby pasture site, where hourly measurements were recorded. Results from the model indicate that measured values on a daily basis were estimated within 20%, while five and ten day running means were calculated within 10% of the measured means. </p> / Thesis / Bachelor of Arts (BA)
