Synthetic Aperture Radar (restricted)Entry ID: gov.noaa.class.SAR
Abstract: ABSTRACT: The CLASS inventory of Synthetic Aperture Radar data includes imagery of global and repetitive observations of the environment. Imagery was obtained by the ERS-1, ERS-2 and RADARSAT-1 satellites, which were flown in sun-synchronous, polar orbits. Imaging was acquired irrespective of weather conditions. The SAR radar sensor is a microwave instrument that sends pulsed signals to the Earth ... and processes the received reflected pulses. Data are processed at one of four sites: Fairbanks, USA; Gatineau, Canada; Tromso, Norway; or West Freugh, UK. Data are in a variety of Beam Mode/Positions and product types (geo-coded or geo-referenced) on various dates.
SUPPLEMENTAL INFORMATION: CLASS allows access to RADARSAT data for authorized U.S. Government users only. It permits the users to search the CLASS inventory of RADARSAT data based on data set type as well as geographic locations and acquisition date and time. The user may then order selected data sets from the inventory for electronic delivery
CURRENTNESS REFERENCE: Ground Condition
Fees: Electronic download (FTP) of the data is free. There is a fee for copies of data on physical media. Optical disks are $25.00 per unit and magnetic tape is $100 per unit. Price does not include additional service and handling costs.
Purpose: PURPOSE: Data generated by the ERS contribute to: * Improved understanding of ocean-atmosphere interactions. * Advances in knowledge of ocean circulation and energy transfer mechanisms. * Improved estimates of the mass balance of the Arctic & Antarctic ice sheets. * Better monitoring of dynamic coastal processes. * Improved pollution monitoring. * Improved detection and management of land use changes. Data generated by Radarsat - 1 contributes to: * Mapping all of the Antarctic ice sheet. * Monitoring sea-ice cover for climate research and navigation purposes. * Monitoring sea-ice cover for climate research and navigation purposes.
