| Abstract | The Tropical Rainfall Measuring Mission is a United States-Japan joint project for rain measurement using a spaceborne rain radar. The authors investigate the rainfall-rate error caused by the effect of non-uniform beam filling on the radar reflectivity and the surface reference technique simulation which employs rain data measured by a ground-based radar. Complete 3D rain data generated from a radar-based volume scan are used, and these 3D rain data are assumed to be true data. To estimate the mean value of the rain echo power, it is essential to take an average of fluctuating radar signals; to estimate that value correctly, a large number of samples is needed. However, the number of averaging samples is limited because the measurement time at spatially fixed points is limited by the continuous movement of the satellite. Thus, instrument-measured quantities always have some errors. This study takes into consideration the error caused by the limited number of averaging samples. |

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.
