Abstract. 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 tech-
nique which merges the satellite observations is used to de-
tect inundation. Monthly flooded areas 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 min-
imum inundated area for the July 1992-June 1993 period
of 2.16x106
