Modified Monte Carlo algorithms are presented for calculating spectral fluxes of short-wave radiation for efficient computation of photosynthetically active radiation (PAR) in the clear-sky atmosphere, overcast, and broken clouds. A database is created for fast calculations of monthly mean PAR values for different geographic latitudes, months, and surface types, using satellite data on the cloud amount. The calculations are compared with ground data for BOREAS NSA (Canada).
