We are constructing a global-scale Earth System Data Record (ESDR) of inundated wetlands to facilitate investigations on their role in climate, biogeochemistry, hydrology, and biodiversity. The ESDR is composed of fine-resolution maps of wetland extent, vegetation type, and seasonal inundation dynamics derived from Synthetic Aperture Radar (SAR) for continental-scale areas covering crucial wetland regions, and global multi-year mappings of inundation extent at coarse resolution derived from multiple satellite data sets. We present details of ESDR construction including remote sensing algorithms, cross-product harmonization, and data system development supporting ESDR construction and product dissemination. This ESDR will provide the first accurate, consistent and comprehensive global-scale data set of wetland inundation and vegetation.
