A further action which was brought forward by E.J.O. Schrama:

Recommendations for temporal reductions in gravity and tidal observations should be formulated.

Subcommission meeting in Cairns 2005

Present: Dan Roman, Luciana Fenoglio, Ernst J.O. Schrama, Michael Kuhn, Hussein Abd-Elmotaal, Roland Schmidt, Thomas Gruber, Pieter Visser, Jaakko Mäkinen, Mattias Becker

Report on work done since Porto:

The Porto Proceedings have appeared.

Upcoming meeting: Istanbul 2006.

A discussion took place on formulating a recommendation for gravimetric reductions. Pieter visser suggested the use of the GRACE models. Thomas Gruber remarked that recommendations are available on the ESA website for GRACE and GOCE.

Jaakko Mäkinen mentioned IAG's own standards as written up by Boedeker in 1988 (reduction to standard atmosphere, etc.)

In the future, this work will undoubtedly be related to GGOS.
