| Abstract | Northern wetlands are known to be a major source of atmospheric methane, however, there are uncertainties about their actual emission characteristics and their links to wetland hydrology and ecology
which lead to poor estimates of total methane production. The Canadian NOrthern WEtlands Study (NOWES) is intended to address these uncertainties for the Hudson Bay Lowlands. In support of the remote sensing component of the
study, airborne multispectral (MEIS) and synthetic aperture radar (SAR) data, along with SPOT HRV and Landsat TM satellite data, were acquired for a representative study area during the summer of 1990 in order to characterize the vegetation cover and
moisture conditions. These data are being used to develop a mesoscale classification of the vegetation types important to methane production. In conjunction with ground data, the classification will be used in a scale-up procedure to develop
relationships between microscale flux measurements, moisture conditions, and land cover. In turn, these relationships will be extrapolated to regional landcover in order to obtain an estimate of methane production for the entire lowland region.
