originator
The dgrav gridded data set was produced by NGDC by regridding the Decade of North American (DNAG) 6-km gravity grid of N. America. A grid cell dimension of 2.5 minutes of longitude and latitude was used in this regridding process. In order to facilitate the comparison of the various regridded data, a geodetic reference system was used as the most suitable common coordinate frame.
To provide easy access to global and regional gravity data and related models for scientific studies.

NOAA National Centers for Environmental Information
NOAA created the National Centers for Environmental Information (NCEI) by merging NOAA's National Climatic Data Center (NCDC), National Geophysical Data Center (NGDC), and National Oceanographic Data Center (NODC), including the National Coastal Data Development Center (NCDDC), per the Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235. NCEI launched publicly on April 22, 2015.

Horizontal Positional Accuracy Report
Horizontal accuracy varies from source contributor to source contributor. However, horizontal positions are usually taken from topographic maps of the area being surveyed. Accuracy may range up to +/- 100 feet.
Vertical Positional Accuracy Report
Vertical accuracy varies from source contributor to source contributor. However, vertical positions are usually taken from topographic maps of the area being surveyed, monumented benchmark locations, or they are determined by the use of the Global Positioning System (GPS). Accuracy may range from meters to centimeters or better.

Quantitative Attribute Accuracy Assessment
Statistical analysis.
Gravity data values are the result of the measurement of small variations in the gravitational field of the Earth. The magnitudes and ranges of these variations are well known in the potential field discipline.

Variable: the average acceleration on the Earth's surface is
about 980 centimeters per second squared, which is equal to 980 gals, but
increases by about 1/2 percent from equator to pole.
