This data release contains data collected during campaign Global Navigation Satellite Systems (GNSS; formerly only the Global Positioning System or GPS) surveys conducted at Mount St. Helens. A survey in any given year may contain data from a subset of established sites depending on access, personnel, and the condition of the GNSS monument. For each site, we include raw data in binary or receiver-specific proprietary, Receiver INdependent EXchange (RINEX, .yyo), and compressed (Hatanaka compression, d.Z) file formats, field log sheets, and associated metadata information.
