USING GPS OBSERVATIONS TO UNDERSTAND THE EARTH: EXAMPLES FROM PBO, COCONET, AND TLALOCNET
COCONet is a multi-hazard GPS-Met observatory, which extends PBO infrastructure into the Caribbean basin. In 2010, UNAVCO was funded by NSF to build and initially maintain a network of 50 new cGPS/Met sites and incorporate another 50 existing sites in the Caribbean region. The revised siting plan calls for 46 new, 21 refurbished, and 77 existing stations spanning 26 nations in the Caribbean.
A new joint UNAVCO-Mexican multi-hazard GPS-Met observatory, called TLALOCNet is also now under constructio. The plan calls for installation of 9 new PBO-quality GPS-Met sites in Mexico and adjacent islands, upgrade 29 sites previously installed with NSF funding along the western subduction boundary, and coordinate with the Mexican National Meteorological Service to federate data from at least another 80 GPS-Met sites distributed across Mexico. All GPS-Met data from TLALOCNet will be freely available at the UNAVCO archive and Mexican mirror sites.
The ultimate goal for these networks is to provide free, high-quality, low-latency data and data products for researchers, educators, students, and the private sector. Data from COCONet and TLALOCNet will be used by US and international scientists to study solid earth processes, for example plate kinematics and dynamic as well as plate boundary interactions and deformation, with an emphasis on the earthquake cycle. The networks also serve atmospheric science objectives by providing more precise estimates of tropospheric water vapor thus enabling better forecast of the dynamics of airborne moisture associated with the yearly Caribbean hurricane cycle.
