GPS/GNSS geodesy contributes to a wide range of scientific and societal applications including tectonic motion, crustal deformation, natural and anthropogenic processes and hazards, including earthquakes, tsunamis, volcanoes, the cryosphere, extreme weather, sea level rise, climate change and hydrology. Our NASA MEaSUREs project “Extended Solid Earth Science ESDR System” (ESESES) provides the basic infrastructure, data and data products in support of these applications in the form of Earth Science Data Records (ESDRs). The project is a long-lived collaborative effort of the Jet Propulsion Laboratory (JPL) and Scripps Institution of Oceanography (SIO) encompassing about 30 years of data. NASA's CDDIS Archive of Space Geodetic Data (CDDIS Main Page; CDDIS Slides) is the Earth Observing System Data and Information System (EOSDIS) Distributed Active Archive Center (DAAC) for our project. Our products are directly accessed here at CDDIS (need to create a NASA Earthdata account) with a landing page describing the project. The ESESES website is hosted by the Scripps Orbit and Permanent Array Center (SOPAC).

07/29/2023: AWG Award. A member of our team Angelyn W. Moore has won the 2023 AWG Professional Excellence Award in the Government/Regulatory category from the Association of Women Scientists (AWG). This award recognizes exceptional women who have made distinguished contributions in their professions throughout their careers. Congratulations Angie!

06/21/2023: New NASA Award. We have been awarded a five-year project, “Geodesy-Based Enhanced Solid Earth Science ESDR System (ESESES) for Research and Discovery” (22-MEASURE22-0037), by NASA's Earth Science Division. This is our fourth five-year MEaSUREs project. The review summary states: "PIs propose to continue the very successful production and enhancement of continuous, global GNSS-related ESDRs to address timely and important tectonics, geohazards and climate science objectives. The expertise of SIO and JPL teams make this effort an essential part of the Earth Science program at NASA."
