The MFRSR is currently in operation and measures global, diffuse and direct normal components of Spectral Solar Irradiance, in six narrow bands approximately 10 nm wide. The data for Solar Irradiance was considered for a clear day (9 October, 2006) as well as a cloudy day (2 October, 2006) skies to study the effect of clouds on Radiation. The results indicated that no atmospheric effects were observed in the variation of total solar irradiance during clear skies. During cloudy skies the atmospheric effects were observed due to clouds. The validation of data with satellite measurements will be conducted and JSU will continue measurements of solar and atmospheric radiation, aerosols, water vapor and ozone optical depths for climate studies and for long-range monitoring of Aerosol Radiation Network (AERADNET). Analysis and retrieval of aerosol and ozone using Longley analysis is in progress.
