| Abstract | The use of satellite scatterometers to probe the winds in and near strong storms and hurricanes is a valuable tool for weather forecasters. The presence of widespread rain in these storms makes the estimates of surface winds from the satellite data problematic. A motivating question here is: “Is there a substantial influence of rain on the air-sea momentum exchange in Hurricanes”. Satellite scatterometer measurements were made for Hurricane Gustav (C-Band), which affected New Orleans on September 1 and Hurricane Ike (Ku-band) which impacted the Texas coastline near Houston, on September 13, 2008. The NEXRAD rain reflectivity images (available every 6 minutes) show that there was wide rain coverage throughout these storms. The sustained surface wind estimates from NOAA/ AOML/ HRD show a maximum of 90 kts, and a wide inhomogeneity even within 50 km areas. The broad swath coverage of the NEXRAD radar enables us to select and compare NRCS effects in both rain and non-raining areas. The methodology to be presented here demonstrates how the atmospheric influence can be removed to observe the total surface NRCS. |

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.
