Table Mountain Gravity Observatory Superconducting Gravity Data Download Site
In April of 1995, the National Oceanic and Atmospheric Administration (NOAA),
as part of their Climate and Global Change Program, installed a GWR compact style superconducting gravimeter at their Table Mountain Gravity Observatory (TMGO) near Boulder, Colorado. The relative gravimeter, C024, is capable of detecting
sub-microgal gravity variations. The instrument is very stable with a linear instrument drift of approximately 8 microgals/year. Data and information on the site are available on this web site. We will try to update the data monthly.
NOAA participates in Global Geodynamics Project, a cooperative project between a number of international organizations, to pool superconducting data sets from around the world to investigate a number of geodynamic problems.
