IceBridge Sander AIRGrav L1B Geolocated Free Air Gravity Anomalies V002
Listed in NASA Earthdata CMR
This data set contains gravity measurements, including acceleration data in three orthogonal directions, from the Sander Geophysics AIRGrav airborne gravity system.
Description
Gravity data include latitude and Eotvos-corrected values, as well as free air correction at various along-flight-line time filtering scales. The data were collected as part of Operation IceBridge funded campaigns.
