Campaign GNSS Measurements Collected at Three Sisters by the Cascades Volcano Observatory

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