摘要

The two ESA Earth Explorer Core missions CryoSat-2 and GOCE provide a unique opportunity for exploring a broad variety of scientific applications in the fields of Geodesy, Oceanography and Cryospheric research. Both missions are currently in orbit and acquiring measurement data. Combining the data derived from the two missions allows computing oceanographic products such as Absolute Dynamic Topography (ADT) with a spatial resolution and accuracy higher than current solutions. To get an idea of possible improvements in spatial resolution and accuracy with respect to the utilization of previous missions’ data, a preliminary case study in the Pacific region will demonstrate the ADT quality. The products used within the case study will be GOCE-only and CryoSat-2-only Low Rate Mode level 2 (LRM L2) datasets on one hand and multi-mission altimetry products and non-GOCE derived geoid models on the other hand. Parameters for comparison are, due to the limited availability of CryoSat-2 data, along track differences and correlation coefficients for single passes of CryoSat-2. An example for an ADT map replacing CryoSat-2 data with Envisat data is presented to show the performance of the techniques applied.
