Evaluation of the Global Altimetric Marine Gravity Field DTU15: Using Marine Gravity and GOCE Satellite Gravity
Global marine gravity field modelling using satellite altimetry has been undergoing constant improvement since the launch of Cryosat-2 mission in 2010. With its 369 day-repeat Cryosat-2 provides one repeat of geodetic mission data with 8 km global resolution each year. Together with the completion o...
