Line 12: As an alternative, '''icosahedral–hexagonal grids''' have been developed to discretize weather and climate models. They are based on truncated icosahedra and dodecahedra. In the 1990s, several research groups have developed icosahedral gridpoint general circulation models using their own new techniques. A few examples are [[GME of Deutscher Wetterdienst]] for the numerical prediction model (Majewski ''et al.'', 2002)., ICON GCM: ICOsahedral Non-hydrostatic General Circulation Model joint project between Max Planck Institute for Meteorology (MPI-M) and the Deutscher Wetterdienst (DWD), CSU AGCM (Atmospheric General Circulation Model) at Colorado State University (Heikes and Randall 1995a, b; Randall ''et al.'', 2000, Randall ''et al.'', 2002; Ringler ''et al.'', 2000) and Nonhydrostatic Icosahedral Atmospheric model of Frontier Research Center for Global Change (Tomita ''et al.'', 2001, 2002; Tomita and Satoh, 2004). == See also == * [[Geodesic grid]] [[Category:Finite differences]]
