Última VALIDATION OF SATELLITE DERIVED LHF USING COARE_3.0 SCHEME AND TIME SERIES DATA OVER NORTH-EAST INDIAN OCEAN Gayana Muraleedharan,P.M.; Pankajakshan,T.; Sathe,P.V.. Time series measurement of surface meteorological parameters using an Autonomous Weather Station and Moored Buoy positioned at 10.5 N and 72 E from July to November 2000 are used to compute latent heat flux (LHF) using COARE_3.0 algorithm for validating Special Sensor Microwave Imager (SSMI) derived LHF data. Mean positive and negative biases are observed between satellite and sea truth derived LHF estimates for summer (July to Sept) and inter-monsoon (Oct-Nov.) seasons respectively. Comparison during summer season exhibits very high correlation ( 75%) and is increasing progressively with longer climatologies. Satellite underestimates higher LHF values during summer while it overestimates lower LHF values in inter-monsoon season. Root Mean Square Deviation...

Ano: 2004 URL: http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0717-65382004000300019 AN INTERACTIVE SOFTWARE PACKAGE FOR VALIDATING SATELLITE DATA Gayana Muraleedharan,P.M.; Pankajakshan,T.. Earth observation satellite launched in the last three decades have made vital contributions to the understanding of the planet. The earth system consisting of land, oceans and atmosphere is linked together by a number of complicated processes. Potential of microwave sensors in studying the boundary layer dynamics of the ocean-atmosphere system is well documented. Technology has revolutionized the application of such sensors and several missions are planned to take off in near future for meeting specific objectives. Launching of such sensors need to be followed by an extensive validation campaign for providing accurate and reliable information to the users. A PC-based interactive system has been developed and presented here for validating satellite mounted...
