Preliminary Map

WDMAM2007

WDMAM version 0.8 was presented at CGMW General Assembly in Paris 9 February 2006.

In this preliminary totali intensity anomaly map the data themes presented data frequency band and reduction as they are, however upward continued to 5 km. 

Now, the final map has been published. The frequency band was further  high cut limited to 2600 km at the Equator and the highest spherical harmonical terms (<100) were replaced by MF5.

Oceanic data gaps were replaced by modelled anomalies, where valid model existed. The remaining data gaps were filled by MF5. The map was scientifically reviewed by CGMW prior to publishing.

Please see the published First Edition of the map: WDMAM2007. 

WDMAM2008

Preliminary map is planned to be shown at EGU2008, April 2008, and displayed.here until the release of WDMAM2008 at IGC33, in Oslo, August 2008.
