This dataset contains absolute-gravity data collected by the USGS Southwest Gravity Program, a collaborative effort of the Arizona, California, and New Mexico Water Science Centers to monitor and model groundwater-storage change. Data were collected following the methods in "Procedures for Field Data Collection, Processing, Quality Assurance and Quality Control, and Archiving of Relative and Absolute-Gravity Surveys", U.S. Geological Survey Techniques and Methods book 2, chapter D4 . All data are reviewed and approved. Additional gravity data, including network-adjusted relative- and absolute-gravity data, may be available in ScienceBase Data Releases.Gravity data are provided as two files:sgp_agdb_stations_YYYY-MM-DD.csv...

These are the QA/QC plans for gravity data collected by the USGS Southwest Gravity Program. The Absolute Gravity QA/QC plan is a final, internally-reviewed document. The gravity Techniques and Methods is a comprehensive draft, subject to revision, for carrying out relative and absolute gravity surveys. Comments are welcome and should be directed to Jeff Kennedy (jkennedy@usgs.gov).

The USGS Southwest Gravity Program carries out hydrologic investigations primarily in the southwestern United States.
This page lists software packages for processing gravity data. It does not include software intended primarily for subsurface modeling, e.g. GM-SYS. The USGS provides no warranty, expressed or implied, as to the correctness of the furnished software or the suitability for any purpose. The software has been tested, but as with any complex software, there could be undetected errors. Users who find errors are requested to report them to the USGS. The USGS has limited resources to assist non-USGS users; however, we make an attempt to fix reported problems and help whenever possible.
