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. The AIRGrav data consist of measurements of aircraft attitude and gravity. Aircraft attitude is provided as one file per flight. 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. A grid channel file in Geosoft exchange format is provided for each area to show the source of grid filter data. Gravity data and aircraft attitude 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 pr
esent via FTP.
