Dedicated satellite gravity missions, such as GOCE, GRACE and GRACE-FO, have been providing essential data for many geodetic and geophysical studies and applications. In the next future, new missions exploiting technological advances and innovative o

Open Data, and Open Government Data, are proving to be an important resource for the economic development inside the domain where information has a key role (Carrara et al., 2015). Although, different practices for data publishing have led to misalig

General ocean circulation models are not perfect. Forced with observed atmospheric fluxes they gradually drift away from measured distributions of temperature and salinity. We suggest data assimilation of absolute dynamical ocean topography (DOT) obs

In 2012 the GEOHALO flight mission was carried out using the new German research aircraft HALO. The surveyed zone covers the Central-South part of Italy, roughly from latitude 36°N to 44°N. In this area, seven main tracks NW to SE were surveyed hav

Physical geodesy is by definition the science which studies and calculates the Earth’s gravity field and its physical form. Satellite physical geodesy exploits satellite techniques to solve the problems established in physical geodesy. During the s

In the framework of a boundary value problem (BVP), when areas on the boundary are void of data the solution of the problem becomes undetermined and clearly more difficult. Physically, this could be the situation in which a gradiometer on a satellite

The recovery of the harmonic coefficients of the anomalous potential from a geodetic quantity sampled over a regular grid is affected by the non-exact discrete orthogonality of spherical harmonics; larger errors occur for block-average quantities owi

Ensemble Kalman filter methods are typically used in combination with one of two localization techniques. One technique is covariance localization, or direct forecast error localization, in which the ensemble-derived forecast error covariance matrix
