Annual Insolation
Function Overview
Annual Insolation is used to estimate the annual solar radiation within a specific area. It samples time points throughout a year according to specified parameters, calculates insolation for each sampling time (day), and outputs a multiband dataset recording insolation values for each time sample. This can be used to assess trends in annual solar radiation for the area.
