Yellowstone’s semi-permanent GPS sensors head home for the winter. Mike Poland, the Scientist-in-Charge of the Yellowstone Volcano Observatory, provides the October update from the warehouse at the Cascades Volcano Observatory, where the YVO field team is getting ready to head out to Yellowstone to pick up instruments that have been collecting data on ground surface changes all summer. Yellowstone volcano is monitored by dozens of GPS stations that continuously radio information to the observatory in real-time, 24/7, 365 days a year. The deformation network also includes semi-permanent GPS that are installed every May and collected in October. These instruments are not connected by a radio link, so data has to be downloaded when the instruments are back at the observatory. The primary purpose of the semi-permanent GPS network is to add to the data collected by the continuous network, to gain a broad picture of changes that happen from year to year. The semi-permanent GPS is also good at c
