Abstract

In Kurtenbach (2011) and Kurtenbach et al. (2012) an approach has been introduced that allows to calculate daily gravity field solutions from GRACE data within the framework of a Kalman filter and smoother estimation. The method utilizes spatial and temporal correlations of the expected gravity field signal derived from geophysical models in addition to the daily observations, thus effectively constraining the spatial and temporal evolution of the GRACE solution. Here, we offer an extended validation of these daily solutions by comparing the derived mass variations to vertical displacements at various permanent GPS stations. The comparison confirms the conclusion that the daily solutions contain significant high-frequent temporal gravity field information, especially in higher latitudes.
