national meteorological service. The model was run using an almost uniform icosahedral-hexagonal grid. The GME grid point approach avoided the disadvantages of spectral techniques as well as the pole problem in latitude–longitude grids and provides a data structure well suited to high efficiency on distributed memory parallel computers. The GME replaced two previous models (the GM and EM), and was first run on 1 December 1999.

Approach

The GME's approach to a global grid would later be utilized by the Flow-following, finite-volume Icosahedral Model (FIM), an experimental model currently in development in the United States. The GME was replaced by the ICON (Icosahedral Nonhydrostatic) model on 20 January 2015. ICON uses the same icosahedral approach, but has a higher resolution at 13 km.
