A NEW GRAVITY DATASET FOR IMPROVING THE IMAGING OF CAMPI FLEGREI CALDERA BOUNDARIES

Database of a new relative gravity survey in the eastern sector of the Campi Flegrei caldera (Italy). Database includes 73 new gravity points supplemented by precise height determinations through co-located GNSS measurements. Database is provieded as a table with the following fields: • Station identification code; • Geographic coordinates (decimal degrees): Latitude; Longitude expressed in the World Geodetic System 1984 reference system; • Projected coordinates (in meters): Easting; Northing projected using a Universal Transversal Mercator (UTM) projection, Zone 33 North; • Orthometric heights (in meters) determined by Real-Time Kinematic (RTK) GNSS measurements;• RMS Elevation: Root mean square error on the elevation (in meters);• RMS horizontal: Root mean square error on the planar coordinates (in meters);• Absolute gravity value at each station (in μGal); • Adjustment error on gravity (in μGal); • Propagated Uncertainty: error on Free air anomaly values by propagating the adjustment error and the error on elevation (in μGal);• Free-Air anomaly value (in mGal).
