| Abstract | Surface cloud radiative forcing was calculated using cloud and surface properties from the International Satellite Cloud Climatology Project (ISCCP) D-series product as input into a radiative transfer model. In addition, the newly extended AVHRR Polar Pathfinder (APP) data set, which includes surface cloud radiative forcing, was used in this 9-year (1985-1993) study. Spatial and temporal trends in the surface net cloud forcing for the Antarctic were examined in both the ISCCP-derived and APP data sets. Monthly means of the ISCCP-derived net cloud radiative forcing at the surface were found to be greater than zero all year-round poleward of 80/spl deg/S. The APP net cloud forcing was found to exceed 10 W/m/sup 2/ south of 80/spl deg/S every month of the year. The differences in the net cloud forcing between the two data sets largely occurs because of differing cloud amounts. Both the ISCCP and APP net surface fluxes were compared to fluxes measured at Neumayer Station. Errors in the monthly mean net all-wave surface flux of up to 50 W/m/sup 2/ were found for the ISCCP-derived product. The APP product errors were found not to exceed 13 W/m/sup 2/ at the monthly time scale. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
