UNAVCO’s primary direct data access point. Subdirectories contain time series, velocities, offsets, earthquake event files, hydrologic loading displacements, etc.
GPS Site Coordinates
List of site coordinates for all active stations via ASCII File processed by the GAGE AC’s and ACC for the most recent epoch (full 24 hour day) available. List is generated dynamically via web services and is continuously updated. Available in IGS14, NAM14, ANT14, IGS08, and NAM08 reference frames.
GPS Site Velocities
Long term GPS velocity field solutions via ASCII File. Estimates of offsets from antenna changes, equipment problems (such as broken radomes), and earthquakes are incorporated. Solutions are from the most recent “snapshot” velocity solution, generated approximately monthly. Available in IGS14, NAM14, ANT14, IGS08, and NAM08 reference frames.
An archive of PBO H2O snow depth, soil moisture, and vegetation data products using GPS reflections were posted every morning. This archive for historic purposes until a new way to generate these products is found.
GPS Time Series via DAI Interactive Plotter
Plots north-south, east-west, and vertical GPS positions over time, for one or more stations on a single plot, and provides site event information such as equipment changes. Also provides easy and direct access to the time series as a simplified, downloadable CSV file. After launching the viewer, enter one or more GPS site 4-char ID(s) in the white field in the upper left (if more than one site then use spaces or commas between 4-char ID’s (e.g., P160, p161). The interactive time series tool is also accessible from within the DAIv2 (by selecting a set of stations and right-clicking). NOTE: the DAIv2 requires Flash to be installed and working in your browser.
GPS Velocities via KMZ
Long term GPS velocity field solutions for the PBO network. Estimates of offsets from antenna changes, equipment problems (such as broken radomes), and earthquakes are incorporated. NOTE: Best used with Google Earth Pro desktop.
GPS Time Series via Network Monitoring Station Pages (UNAVCO Operated Stations Only) NOTE: intended for station status only. Some data and products are linked from these station pages but this is NOT a primary data access point as only a subset of existing stations/data are available from this interface. The primary data access points for UNAVCO data are the DAIv2 and the FTP site. See also: Nearby timeseries plots.
Quarterly technical reports describing GAGE GPS analysis activities are provided by the Analysis Center Coordinator at MIT. These reports summarize statistics for all stations analyzed during the period as well as processing notes, station offsets, etc.
