Dataset Abstract:

Multi-scale analysis of inundation and wetland vegetation with microwave and optical remote sensing in the Amazon Basin. Collaborative activities conducted at UCSB and INPE focused on analysis of basin-scale optical and microwave data to characterize inundation and wetland vegetation, development of new interferometric and polarimetric synthetic aperture radar (SAR) techniques for examination of floodplains, and coordination and execution of a basin-wide airborne campaign to acquire videographic and laser altimetry data over wetlands and other LBA sites. Using the methods and algorithms that we have developed for determining flooded area with the 37 GHZ polarization difference observed by the Scanning Multichannel Microwave Radiometer, we have completed a monthly time series for seven years of inundation area for the central Amazon and Llanos de Mojos. The high and low water acquisitions of JERS SAR coverage of almost the whole Amazon Basin offers us a rich dataset; we have applied INPE's segmentation algorithms to conduct of polygon-based classification of wetlands using the JERS data. Further, we have developed a method for classifying and mapping floodplain habitats by linking multi-date SAR imagery with river stage records, incorporating information on both vegetation structure and inundation periodicity, and applied the method to sites in the central Amazon. In addition, we have demonstrated that interferometric SAR is capable of measuring subtle changes in water level in regions with inundated vegetation. Using SIR-C data from the central Amazon, we were able to determine 2 to 9 cm/day changes in water level in hundreds of floodplain lakes. Recent analyses of the mainstem Amazon floodplain based on Landsat Thematic Mapper images indicate considerable landscape heterogeneity. Upstream reaches are dominated by forests, which transition through the middle reaches to lower reaches dominated by macrophytes. By combining field measurements of methane emissions with our analyses of inundation and vegetation, we calculate a regional estimate of methane emission from the central Amazon of about 1.8 Tg C per year.
