SWAMPS was derived using a land cover-supported, atmospherically-corrected dynamic mixture model applied to 20+ years of combined, daily, passive/active microwave remote sensing data. Learn more

This data set has been used in projects looking at large scale inundation patterns and methane modeling in wetlands across the globe.
