Downward continuation of airborne gravity data

  title={Downward continuation of airborne gravity data},
  author={Ren{\'e} Forsberg},
$EVWUDFW With airborne gravimetry routinely reaching accuracies of 1-2 mGal at 5-10 km resolution, it is a challenge to perform a reliable downward continuation of the gravity anomalies at altitude. Airborne gravimetry is especially suited for geoid determination in mountainous and polar regions, due to the random, alias-free sampling of the terrain, relative to typical surface surveys. In the paper different operational methods based on collocation and FFT are outlined, and applied to downward… CONTINUE READING
