From: A New GPS SNR-based Combination Approach for Land Surface Snow Depth Monitoring
Effects of snow depth height on oscillation fringe visibility and amplitude power at GPS L1, L2 and L5 carriers for a geodetic antenna at the YEL2 site; labels refer to 0 and 0.340 m snow height values. (a) Detrended SNR observations; (b) L–S periodogram of dSNR observations.
