   Description: 
      Abstract:
         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.
