The most accurate measurements of solar radiation are obtained by a pyrometer placed at a location for a number of years, usually on the order of a decade or more, measuring the direct radiation every few minutes. Solar Irradiance. The Total Irradiance Monitor (TIM) measures the total solar irradiance (TSI), monitoring the incident radiant energy powering the Earth’s climate system. This decision recognizes that no computational model is perfect and that the inputs to each model are characterized by uncertainties that depend on terrain type and environmental conditions, which leads to performance variations across locations.
