Abstract The Global Navigation Satellite Systems (GNSS), including the US's GPS, China's
BDS, the European Union's Galileo, and Russia's GLONASS, offer real-time, all-weather …

The global navigation satellite system-reflectometry (GNSS-R) field has experienced an
exponential growth as it is becoming relevant to many applications and has captivated the …

In traditional GNSS applications, signals arriving at a receiver's antenna from nearby
reflecting surfaces (multipath) interfere with the signals received directly from the satellites …

Soil moisture is an essential climate variable influencing land–atmosphere interactions, an
essential hydrologic variable impacting rainfall–runoff processes, an essential ecological …

This paper presents recent efforts to understand the relative accuracies of different
instrumentation and gauges with various windshield configurations to measure snowfall …

Snow is an important component of the climate system and a critical storage component in
the hydrologic cycle. However, in situ observations of snow distribution are sparse, and …

Accurate measurements of snowpack are needed both by scientists to model climate and by
water supply managers to predict/mitigate drought and flood conditions. Existing in situ snow …

Measurements of soil moisture at various spatial and temporal scales are needed to study
the water and carbon cycles. While satellite missions have been planned to measure soil …

Global Positioning System (GPS) multipath signals can be used to infer volumetric soil
moisture around a GPS antenna. While most GPS users concentrate on the signal that …

Multipath is detrimental for both GPS positioning and timing applications. However, the
benefits of GPS multipath for reflectometry have become increasingly clear for soil moisture …
