亚马孙河流域的瑞典是全球重要的大气甲烷来源。利用卫星遥感（被动和主动微波）对淹没和植被的时间变化程度与野外测量相结合，计算了亚马逊湿地的区域甲烷排放率。利用扫描多通道微波辐射计1979 ~ 1987年观测到的37 GHz极化差，得出了索里莫斯河/亚马逊河主干线边缘洪泛平原的月淹没面积。利用l波段合成孔径雷达数据（日本地球资源卫星1号）确定亚马逊流域的淹没和湿地植被(
sWetlands of the Amazon River basin are globally significant sources of atmospheric methane. Satellite remote sensing (passive and active microwave) of the temporally varying extent of inundation and vegetation was combined with field measurements to calculate regional rates of methane emission for Amazonian wetlands. Monthly inundation areas for the fringing floodplains of the mainstem Solimoes/Amazon River were derived from analysis of the 37 GHz polarization difference observed by the Scanning Multichannel Microwave Radiometer from 1979 to 1987. L-band synthetic aperture radar data (Japanese Earth Resources Satellite-1) were used to determine inundation and wetland vegetation for the Amazon basin (
