THE AMAZON DENSE GNSS METEOROLOGICAL NETWORK

Dense networks anchored to these Mexican and Caribbean sites would offer a wide variety of topographic settings and meteorological regimes to complement sea-breeze and continental tropical data from Brazil described above. Since even unstable oceanic platforms can be employed, the expansion of GNSS meteorology into viable tropical oceanic regions should be promoted over ocean; local surface evaporation is a small contributor to PWV and well-measured, strengthening the interpretation of dPWV/dt as representative of vertical motion (Yasunaga et al. 2008). [...]for the long term, the precision of GNSS-derived PWV will increase as more satellites come online in addition to GPS [e.g., the Global Navigation Satellite System (GLONASS), Galileo, and the BeiDou Navigation Satellite System (BDS)], increasing the value of this stable platform for observing global climate variability.
