REGNOM: cGPS daily position time series

Overview The ocurrence of the Mw7.2 El Mayor-Cucapah earthquake (EMC) on April 5, 2010 marked a turning point in the developement of geodetic instrumentation in northern Baja California, Mexico. Today, the Geodetic Network of Northwestern Mexico (also known as REGNOM) consist of 27 continuous GPS (cGPS) stations designed to study crustal deformation, seismotectonics and seismogeodesy in northwestern Mexico. REGNOM is part of the Northwest Mexico Seismic Network (Vidal‐Villegas et al. 2018). These cGPS sites are distributed across the Peninsular Ranges and the Mexicali Valley in the southern Salton Trough, both in Baja California, with additional stations located in the Gran Desierto de Altar in Sonora, Mexico. The main collaborating research and analysis agencies include the EarthScope Consortium, the National Seismological Service of Mexico, and the U.S. Geological Survey. Objectives REGNOM's main objective is to provide accurate coordinates within a geodetic reference frame, which is fundamental for science and engineering. Specific goals Estimate a regional reference frame for tectonic studies. Provide long-term crustal deformation estimates. Charaterize the commulative elastic deformation along different fault systems in northern Baja California. Study the seismic cycle of the region. Complement the seismic measurements of moderate magnitud earthquakes. Make GPS/GNSS data available for survey applications, such as engineering proyects and topographic measurements, would foster interdisciplinary collaboration and broaden the impact of geodetic research. Description This cGPS dataset consists of 16 daily position time series (enu) sapanning from April 5, 2010 to November 26, 2022. Daily relative positioning was obtained using GAMIT software package, which processes phase data in a double-difference scheme between satellites and stations The processing includes the application of final orbits, atmospheric delay corrections (ionospheric and tropospheric) and ambiguity resolution of the carrier phase (Herring et al. 2018a; Herring et al. 2018b). Position time series were generated with the GLOBK module (Herring et al., 2015; T. A. Herring et al. 2018b). The reference frame implemented is the IGB14-fixed to North America.
