Entry ID

IGGRV1B

Summary

The IceBridge Sander AIRGrav L1B Geolocated Free Air Gravity Anomalies (IGGRV1B) data set contains Greenland and Antarctica gravity measurements taken from the Sander Geophysics AIRGrav airborne gravity system. Gravity data include latitude and Etovos corrected values, and the free air correction at various along-flight-line spatial filtering scales. Gravity data are divided into one file for each geographic area plus an additional file containing all remaining transit lines not used elsewhere. Data are in Geosoft ASCII format. The data were collected as part of Operation IceBridge funded campaigns, and are available for periodic, ongoing campaigns from 16 October 2009 to the present via FTP.
