The accuracy and precision of GPS-MR retrievals are evaluated at three different sites: grasslands, alpine, and forested. The assessment yields a correlation of 0.98 and an rms error of 6-8 cm for observed snow depths of up to 2.5 m. GPS-MR underestimates in situ snow depth by 10%-15% at these three sites, although the validation methods do not measure the same footprint as GPS-MR.6564-6573engArtificial satelliteselectromagnetic reflectionglobal positioning systeminterferometersmultipath channelsradar remote sensingArtigo10.1109/TGRS.2013.2297688WOS:000337173200047Acesso restrito
