| Abstract | Net radiation, at the Earth's surface, is a key variable of interest in fields such as hydrology, climate research, and agriculture. Retrieval algorithms for estimation of the surface radiation budget (SRB) from remote sensing data generally suffer from two major shortcomings: difficulty in dealing with cloudy-sky conditions and reliance on study-site specific ancillary ground data. In this paper, we use the methodology of Bisht and Bras (BB10) to estimate SRB and its components, using only remote sensing data under all sky conditions. The BB10 framework is applied over seven sites of the Surface Radiation Budget network in the CONtinental United States (CONUS), along with 21 sites of the Atmospheric Radiation Measurement program in the Southern Great Plains. The data from both the Aqua and Terra satellites are used for entire 2006. The study examines instantaneous upwelling and downwelling shortwave, longwave, net shortwave, and net radiations, as well as daily average net shortwave and net radiations. The root-mean-square errors of estimated daily average net radiation and daily average net shortwave radiation when compared to ground observations are 52.42 and 52.21 W · m-2, respectively. An example of the retrieved instantaneous and daily average net radiation is also presented, which highlights the limitation of using only polar-orbiting satellite data in estimating the diurnal cycle of net radiation. Two adaptations to the algorithm are presented that make the production of SRB estimates over the CONUS feasible. Finally, the methodology is applied to produce daily SRB maps for the CONUS, and monthly SRB maps are presented. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
