The Earth's gravity field, its recovery instruments, its determination and
interpretation have been at the center of the scientific work of our
colleague Peter Schwintzer, who unexpectedly passed away on December 24th 2004.
As one of the master minds behind the French-German GRIM gravity model series
he has been working on the determination of the gravity model from satellite
data, making major contributions to the evolution of the dynamic orbit
determination and gravity recovery method as a state-of-the-art technique.
On the methodology side he had been contributing to important studies
promoting advanced satellite-based recovery techniques like the
satellite-to-satellite tracking (SST) concept, which eventually led to
a successful realization of the German CHAMP mission as the first of the
modern gravity satellites CHAMP, GRACE and GOCE. As head of section 1.3
'Gravity Field and Earth Models' at GFZ Potsdam he additionally mentored the
establishment of aerogravimetry and supra-conducting gravimeters at GFZ
closing the loop from space-borne to terrestrial data.
On the application and interpretation side his working extended from
relations of the Earth's gravity field to geophysical processes in the
Earth's interior to its usage in the understanding of surface-related
mass transport processes. His sudden death has been a big loss to his
family, friends as well as the geodetic community.
In this session we want to memorize the wide set of working fields of Peter
Schwintzer by inviting presentations related to the following topics:
- Global gravity recovery from satellite-only and surface data in particular
based on CHAMP, GRACE and GOCE.
- Gravity recovery from aerogravimetry and terrestrial (supra-conducting)
gravimeters.
- The derivation of temporal variations of the gravity field with emphasis
on methodology (in order to distinguish from session G2 which is focussed
on applications).
- Interaction of the (static) gravity field with the Earth's interior.
Possible contributions could be related to recent processing results, an
accuracy assessment of the obtained gravity quantities, but also new
methodological developments, synergies or simulation studies.
