A Review of Weather Events in Alaska and Canada with USArray TA Stations

Approximately forty stations within Alaska and Canada’s USArray Transportable Array (TA) Network will be installed with Vaisala WXT520 weather stations by the end of 2016.  Currently, this footprint is concentrated within the northeastern quadrant of Alaska, with smaller groups including: three stations in the southwest near the panhandle, four along western Canada inland from Alaska’s Yakutat Bay, and isolated stations near Barrow, Alaska and in Canada’s Yukon and Northwest Territories.  Each Vaisala WXT520 is capable of recording pressure, temperature, humidity, rainfall, hail, and surface wind at 1 sps resolution.  Furthermore, all TA stations are installed with a Hyperion infrasound microphone, Setra 278 barometer, and a MEMS micro-barometer, that are all also capable of recording at 1 sps.  Here we will present observations from various weather events within Alaska and Canada during the latter half of 2016.  We will also compare the observations from these TA sites with those from nearby monitoring networks.
