2.0  Model Description:

     The PSU/NCAR mesoscale model is a limited-area, nonhydrostatic or 
     hydrostatic (Version 2 only), terrain-following sigma-coordinate 
     model designed to simulate or predict mesoscale and regional-scale 
     atmospheric circulation. It has been developed at Penn State and 
     NCAR as a community mesoscale model and is continuously being 
     improved by contributions from users at several universities and 
     government laboratories.

     The Fifth-Generation NCAR / Penn State Mesoscale Model (MM5) is 
     the latest in a series that developed from a mesoscale model used 
     by Anthes at Penn State in the early 70's that was later documented 
     by Anthes and Warner (1978). Since that time, it has undergone many 
     changes designed to broaden its usage. These include (i) a 
     multiple-nest capability, (ii) nonhydrostatic dynamics, which 
     allows the model to be used at a few-kilometer scale, (iii) 
     multitasking capability on shared- and distributed-memory machines, 
     (iv) a four-dimensional data-assimilation capability, and (v) more 
     physics options.

     The model (known as MM5) is supported by several auxiliary programs, 
     which are referred to collectively as the MM5 modeling system.
