Technical University Munich, GERMANY
New GOCE gravity field models based on about 2 years of completely reprocessed gradiometer data have been released in spring this year to the user community. They were obtained based on different processing strategies and reflect the state-of-the-art of GOCE gravity field models. With the improved gravity gradients resulting from a number of updates implemented in the level 1B processor and with the increased data volume the performance of the resulting GOCE based models could be significantly improved as compared to the previous solutions. The paper provides an overview about the characteristics of the available GOCE models and estimates of their performance based on validation results.
