Photometric quantities for solar irradiance modeling

Modeling Solar Lyman Alpha Irradiance

Solar Lyman alpha irradiance is estimat,ed from various solar indices using linear regression analyses. Models developed with ~nultiple linear regression analysis, including daily values and 81-clay running means of solar indices, predict reasonably well both the shortand long-term variations observed in Lyman alpha. It is shown that the full disk equivalent width of tlle He line at 1083 111x1 ...

Solar Irradiance Forecasting for the Management of Solar Energy Systems

Solar energy is expected to contribute major shares of the future global energy supply. Due to its fluctuating nature an efficient use will require reliable forecast information of its availability in various time and spatial scales depending on the application. The current status of forecasting solar irradiance for energy generation purposes is briefly reviewed with respect to very short-term ...

Modeling Total Solar Irradiance Variations Using Automated Classification Software On Mount Wilson Data Solar Physics

We present the results using the AutoClass analysis application available at NASA/Ames Intelligent Systems Div. (2002) which is a Bayesian, finite mixture model classification system developed by Cheeseman and Stutz (1996) . We apply this system to Mount Wilson Solar Observatory (MWO) intensity and magnetogram images and classify individual pixels on the solar surface to calculate daily indices...
