Fig. 2From: Spatial comparison of inland water observations from CYGNSS, MODIS, Landsat, and commercial satellite imageryComparison Water Mask derived from CYGNSS, Landsat, and MODIS for the contiguous United States between latitudes of approximately 24–37°N for 2019. A 1-km Comparison Water Mask across the study area for 2019 derived from the CYGNSS, Landsat, and MODIS bivariate water masks. B The 1-km Comparison Water Mask subdivided into USGS Hydrological Unit Code-02 Watersheds. The watersheds are referred to as the South Atlantic Gulf basin (B03), the Tennessee basin (B06), the Lower Mississippi basin (B08), the Arkansas-White River basin (B11), the Texas-Gulf basin (B12), the Rio Grande basin (B13), the Lower Colorado (B15), and the California basin (B18)Back to article page
