PENTICTON SOLAR RADIO FLUX VALUES (from SGD Explanation of Data Reports) Daily Solar Flux Values - Penticton -- Daily measurements of the integrated emission from the solar disc at 2800MHz (10.7cm wavelength) have been made by the National Research Council of Canada since 1947. ... The data are tabulated in two forms: the "observed flux" (S), and the "adjusted flux" (Sa). ... The "observed flux" values are useful in ionospheric physics and other terrestrial consequences of solar activity. ...

PROJECT SUMMARY (max 3000 characters) The principal goals of the project are the observational and theoretical investigation of complex cosmic objects where the processes of dust scattering, absorption and emission play significant roles. ... Development of light scattering theory and computer codes to calculate the optical properties of non-spherical inhomogeneous particles and laboratory measurements of light scattering characteristics of irregularly shaped particles. ...
