Prigent, C., E. Matthews, F. Aires, and W.B. Rossow, 2001: Remote sensing of global wetland dynamics with multiple satellite data sets. Geophys. Res. Lett., 28, 4631, doi:10.1029/2001GL013263.

This study is the first global effort to quantify seasonality and extent of inundation with a suite of satellite observations, including passive and active microwave along with visible and infrared measurements. A clustering technique which merges the satellite observations is used to detect inumdation. Monthly flooded aread are then calculated by estimating pixel fractional coverage of flooding using the passive microwave signal and a linear mixture model with end-members calibrated with radar observations to account for vegetation cover. The global results, comprising natural wetlands, irrigated rice, and lakes/rivers, indicate a minimum inundated area for the July 1992-June 1993 period of 2.16x106 km2, about 38% of the maximum 5.75x106 km2, to be compared to maximum areas of 5.35x106 km2 and 5.7x106 km2 from independent data sets. Comprehensive evaluation requires substantial additions to the sparse observational record available.
