RSS-10: Satellite Estimation of PAR and UV-B Irradiances and Long Term Estimates of Trends of UV-B from Ozone Depletion and Cloud Variability at the BOREAS Sites

P.I.(s): Brent Holben -- NASA/Goddard Space Flight Center
Co-I(s): Pawan Bhartia -- NASA/GSFC

Objectives: To investigate from ground and satellite observations the magnitude of daily, seasonal and yearly variations of UV-B irradiance during the course of the BOREAS field experiment and to examine the 14 year record of Total Ozone Mapping Spectrometer (TOMS) data over the BOREAS sites for ozone and cloud reflectance variability. We are also estimating the incident Photosynthetically Active Radiation (PAR) by refining existing model which utilizes TOMS reflectivity data to account for cloud attenuation. In addition, we plan to extend the results of our algorithm development for application to the entire circumpolar boreal forest biome.
