Abstract:
TLALOCNet is a network of continuous GPS and meteorology stations in Mexico to study solid earth processes such as plate kinematics, plate boundary deformation, and the earthquake cycle; in addition, by providing more precise estimates of tropospheric water vapor to investigate, model and forecast North American Monsoon precipitation as well as the Pacific and Caribbean-Gulf of Mexico hurricane cycle, atmospheric science objectives are also addressed. Once completed, this network will span all of Mexico with a strong emphasis on the southern and western Mexico coverage. TLALOCNet links existing GPS infrastructure in North America and the Caribbean aiming towards creating a continuous, federated network of networks in the Americas. Phase 1 (2014-2016), funded by NSF and UNAM, is building and upgrading 30+ cGPS-Met sites to the high standard of the EarthScope Plate Boundary Observatory (PBO). Phase 2 (2016) will add ~25 more cGPS-Met stations funded through CONACyT.

TLALOCNet provides open and freely available raw GPS data, GPS-PWV, and surface meteorology measurements, and time series of daily positions, to support a broad range of geoscience investigations. This is accomplished through the development of the TLALOCNet data center (http://tlalocnet.udg.mx) that serves as a collection and distribution point. This data center is based on UNAVCO’s Dataworks-GSAC software and will also work as part of UNAVCO’s seamless archive for discovery, sharing, and access to GPS data. The TLALOCNet data center also contains contributed GPS-Met data from several regional networks in Mexico. By using the same protocols and structure as the UNAVCO and other COCONet regional data centers, the scientific community has the capability of accessing data from a large number of academically operated Mexican GPS sites. This archive provides a fully querable and scriptable GPS and Meteorological data retrieval point. Additionally Real-time 1Hz streams from selected TLALOCNet stations are available in BINEX, RTCM 2.3 and RTCM 3.1 formats via the Networked Transport of RTCM via Internet Protocol (NTRIP).
