Fig. 1From: Spatial comparison of inland water observations from CYGNSS, MODIS, Landsat, and commercial satellite imageryCYGNSS observations and bivariate water mask products for the contiguous United States between latitudes of approximately 24–37°N for 2019. A Spatial plot of CYGNSS 1-km 50th percentile surface reflectivity signal-to-noise-ratio (SNR) data. B CYGNSS bivariate water mask at 1-km spatial resolution derived from basin-specific binary thresholding of SNR values. C MODIS bivariate water mask at 1-km spatial resolution derived from the Land Water Mask (MCD12Q1) for 2019. D Landsat bivariate water mask at 1-km spatial resolution derived from the Landsat Global Surface Water product (commonly referred to as the Pekel water mask) for 2019Back to article page
