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 Archive of Space Geodetic Data (CDDIS)  is the Earth Observing System Data and Information System (EOSDIS) Distributed Active Archive Center (DAAC) for the project.

10/26/2020: A member of our team, Dr. Donald F. Argus (JPL), received the 2020 George P. Woollard award from the Geological Society of America.  In recognition, he has been invited to present the Geophysics and Geodynamics Division Woollard Lecture on Tuesday, 27 October 2020 at 5:30 PM- 7 PM (East Coast time) on the topic “Change in water at Earth's surface from GPS elastic displacements and GRACE gravity California drought and Rise of the Great Lakes.” Congratulations Donald!
