By the end of 2015, approximately 100 stations from Earthscope's USArray Transportable Array (TA) network will be installed and operating throughout Alaska. This will amount to well over one-third of the total planned deployment through 2017. The increasing density of station coverage has enhanced the utility for the TA network to monitor weather events within Alaska in near real-time. Each station is capable of recording surface pressure observations at 1 sps, and some have even been installed with Vaisala WXT520 weather stations. These data capabilities are in addition to the standard 40 sps seismic data collected at each site. In this presentation we will discuss how observations from some of these Alaskan TA stations compare with those from surrounding National Weather Service stations. We will also present a revised footprint of the projected TA deployment in an effort to advertise the extent of the TA's monitoring region and how it compares with the NWS footprint.
