Abstract

This research effort has the goal of developing quantitative and qualitative coastal and hydrologic applications of ALOS L-band PALSAR imagery for the CoastWatch program of the National Oceanic and Atmospheric Administration (NOAA). These applications will eventually be evaluated by operational agencies within near-real-time applications demonstrations. Targeted applications are high-resolution ocean surface winds, vessel positions, oil spill mapping, oceanic and atmospheric feature detection, sea ice detection and classification, and monitoring of river ice breakup and associated flooding. Early results for this project were obtained through the use of C-band synthetic aperture radar (SAR) data from the RADARSAT-1 satellite and more recently from the Advanced SAR (ASAR) on the ENVISAT satellite. Now that ALOS PALSAR data has became available, SAR product processing algorithms are being modified, tested, and evaluated with L-band data. Data system changes are underway to obtain the PALSAR data in near-real-time in order to provide products timely enough to be useful for weather forecasting and operational ocean monitoring and management. Once the algorithms have been validated and the data system is working in near-real-time, products will be evaluated within the Alaska SAR Demonstration which has been providing NOAA CoastWatch and other operational programs with SAR-derived products in an applications demonstration for the purpose of evaluating their utility to weather forecasting, fisheries enforcement, hazard response, hydrology, and oceanographic/meteorological research. Results of L-band coastal wind research and L-band vessel detection are discussed.
