Table 3 Inferred values of snow depth, snow density, SWE, and SE using the GPS-IRT (nonzero ground tilt) method

From: Estimating snow water equivalent for a slightly tilted snow-covered prairie grass field by GPS interferometric reflectometry

Method Snow depth (cm) Snow density (g∙cm-3) SWE (g∙cm-2) SE (dB)
GPS-IRT PRN 15 13.0 (18.3) 0.08 (0.12) 1.04 (2.20) 0.377 (0.642)
GPS-IRT PRN 18 11.7 (17.5) 0.09 (0.14) 1.05 (2.45) 0.760 (0.798)
GPS-IRT AVG 12.4 (17.9) 0.085 (0.13) 1.05 (2.33) 0.573 (0.721)
In situ 17.6 ± 1.5 0.08 ± 0.02 1.40 ± 0.36  
  1. The inferred values using the GPS-IR (zero ground tilt) method [17] are shown in parenthesis. The arithmetical average (AVG) inferred values are also shown. Each in situ range value consists of 11 measurements.
