Conteúdo: 	The Pantanal is characterized by seasonal inundation of was floodplains. Knowledge of the areal extent and seasonality of the flooding is required to understand the hydrology, biogeochemistry and ecology of the region. This information is also necessary for management decisions, and to identify the potential impacts of proposed development projects such as the Parana-Paraguay Waterway (Hidrovia). In contrast to optical systems, passive microwave remote sensing from satellites can detect inundation when clouds and vegetation are present. The polarized brightness temperatures observed by satellite at 37 GHz provide a sensitive indicator of the presence of surface water (Choudhury, 1991). Passive microwave satellite observtions are available from 1979 to the present, at intervals of weekly or better. These observations have been made by the Scanning Multichannel Microwave Radiometer (SMMR) operated on board the nimbus-7 satellite (1979-1987), and by the Special Sensor Microwave/Imager (SSM/I) instruments as part of the Defense Meteorological Satellite Program (1987-present).
