The Scientific Value of High-Rate, Low-Latency GPS Data; A White Paper [PDF] Ongoing upgrades of western U.S. GPS networks to high-rate, low-latency data transmission capabilities has drawn attention to the interest that the scientific community has in these data. GPS provides an essential complement to other geophysical networks (e.g. seismic, strain, gravity) because of its high precision, sensitivity to the longest period bands, its ease of deployment, and its ability to make measurements of displacement that are local to global in scale.

Using TLS to Improve Models of Volcano Conduit Processes In volcanology, diverse numerical models of conduit flow have been developed to relate the properties of these flows to processes that occur at the surface during eruptions. Conduit models incorporate varying degrees of complexity and account for the transport properties of magmas, steady-state or transient behavior, and conduit geometry (e.g., 1- to 1.5 D, variable width and erodable conduit walls).
