Abstract:
Tens of thousands of high-precision GPS receivers are operating around the world. With very few exceptions, the primary use of these receivers is to measure position. However, we now know that reflection data collected by these receivers can be used to measure shallow soil moisture variations, snow depth, and vegetation water content. If properly situated, many can measure sea level. A portal dedicated to environmental products derived from reflected GPS signals from the NSF EarthScope Plate Boundary Observatory, a large network in the western United States, is now available and updated daily at http://xenon.colorado.edu/portal. I will outline the methodology used by PBO H2O and validation results for each of these products. GPS reflections have a footprint that is intermediate to more typical in situ sensors and satellite data. These products are primarily useful for climate studies and satellite validation.
