Comparison of global Earth’s gravity field models with the aerogravimetric data obtained during a transcontinental flight

Some methodological features of the airborne gravity surveys of Russia’s territory at the latitude of 60° from Arkhangelsk to Kamchatka are described. The results of these surveys are presented. The data obtained from gravimeters installed aboard an aircraft laboratory are compared with EGM2008 and EIGEN-6C3, the state-of-the-art global Earth gravity field models. It is shown that the present-day models have the highest errors near the coastal tectonic structures of the Kamchatka Peninsula.
