This study focuses on the estimation of shortwave and longwave radiation utilizing measured data from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on the National Aeronautic and Space Administration (NASA’s) Terra / Aqua satellites in clear sky conditions. The net radiation is the vector sum of the shortwave and longwave radiation coming towards and going away from the Earth’s surface. The study is carried out for a tropical site Kaiga, located in Southern India for the months of March and April representative of the warm season and the months of November and December representative of the cold season in the year 2013. The validity of the net radiation values estimated from MODIS data is assessed by comparing it with simultaneous ground based measurements from the Mini Boundary Layer Masts (MBLMs). The results indicate that the net radiation values estimated by the satellite are well correlated with the ground based measurements (R2 = 0.983). On an average, for the four months of study, the mean absolute error between the satellite and ground based measurements is 35 W m-2 where as the RMSE is 50 W m-2. Once validated with ground based measurements, the satellite derived net radiation data can be used for validation of land surface energy balance predicted by atmospheric models.
