Abstract:
The Net Surface Shortwave Radiation (NSSR) at the Earth's surface drives evapotranspiration, photosynthesis and other physical and biological processes. The primary objective of this study is to estimate NSSR using multispectral narrowband data of the National Polar-orbiting Operational Environmental Satellite System (NPOESS) Visible Infrared Imaging Radiometer Suite (VIIRS). A method to convert narrowband reflectance to broadband albedo at TOA with VIIRS data is developed and retrieval of NSSR from TOA broadband albedo is also carried out. Accurate radiative transfer model MODTRAN 5 was used to simulate these physical quantities, and the least squares method is applied to get coefficients. The RMSE of Narrowband-to-broadband albedo conversion results is 0.011. And the RMSE of between actual and simulated NSSR in clear sky condition is 50.2 W/m2.
