Application of Monte Carlo Techniques to Insolation Characterization and Prediction. Status Report, 1 October 1978-1 June 1979

摘要

The Monte Carlo method is used to investigate solar radiaion transport through the atmosphere and its reflection from the earth's surface. The rigorous model used allows a detailed understanding of the various aspects of the radiation field at the earth's surface. This knowledge can be used to compare and formulate simple models that are more appropriate for work on solar applications. Phenomena of interest include: the spectral distribution of direct, diffuse-sky, and ground-reflected insolation; the total broadband insolation; circumsolar insolation; the effect of ground albedo; the relationship between insolation on horizontal surfaces and insolation on tilted surfaces; the importance of higher orders of scattering and reflection; the effects of clouds; and the effects of various types of atmospheric aerosols. This report is preliminary in nature in that it is primarily a description of the Monte Carlo method itself and its applications rather than a detailed presentation of results used in solar radiation transport calculations.
