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

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.
