AMD - DIF Record(s) USAP-1929991_1 Abstract Visalia WXT520 weather station hourly data spanning 20 months (with data gaps) at the Cavity and Channel AMIGOS-III sites (Automated Meteorology-Ice-Geophysics Observing System) on the Thwaites Eastern Ice Shelf, Antarctica. Data are reported as the values from the sensors delivered through the Iridium modem via SBD from the AMIGOS. The units were installed at ~6.5m above the surface initially, with snow accumulation gradually reducing that to an estimated 3.5 m after 20 months. The stations report wind direction and speed, air temperature, humidity, pressure, and station power. The two sites latest positions (01 Oct, 2021) are: Cavity AMIGOS: 75.037°S, 105.58°W Channel AMIGOS: 75.049°S, 105.44°W both stations are moving NNE at roughly 850 m.yr, having accelerated from about 650 m/yr in early 2020.
