MM5 World Wide Data

MM5 is a widely-used three-dimensional numerical meteorological model which contains non-hydrostatic dynamics, a variety of physics options for parameterizing cumulus clouds, microphysics, the planetary boundary layer and atmospheric radiation. MM5 has the capability to perform Four Dimensional Data Assimilation (FDDA). MM5 is capable of simulating a variety of meteorological phenomena such as tropical cyclones, severe convective storms, sea-land breezes, and terrain forced flows such as mountain valley wind systems.

In order to facilitate the use of advanced non-steady-state air quality modeling techniques such as CALPUFF in areas with sparse or no meteorological observations, TRC is making available MM5 datasets in a convenient tiled data format or as native binary MM5 output files. Both dataset formats are provided with extraction software to create CALMET-ready 3D.DAT files. CALMET can be run in "No-Observations Mode" with no other meteorological data other than the MM5 data, or it can be run in "Hybrid Mode" using observations together with the MM5 dataset (CALMET can also be run in an "Observations Only" mode using only observational data.)
