The
HOTMAC/RAPTAD system is a userfriendly, cost effective way to simulate
various whatif scenarios in the computer, which is impossible to do with
field measurements, but necessary for planning or mitigating potential
environmental catastrophes.
This complete system includes a preprocessor,
mesoscale meteorological code, a transport and diffusion code, a postprocessor
with realistic graphical 2D and 3D displays, and extensive graphical user
interfaces (GUI).
The modeling system is applicable from building scale to mesoscale (~2000
km).
HOTMAC®
(Higher Order Turbulence Model for Atmospheric
Circulation) is a threedimensional mesoscale prediction model that
forecasts wind, turbulence, humidity, and atmospheric turbulence
distribution around urban areas and buildings in complex terrain
and coastal regions.

RAPTAD®
(Random Puff Transport and Diffusion) is a threedimensional
Lagrangian random puff model that is used to forecast transport
and diffusion of air pollution materials over complex terrain.


Features
include nonhydrostatic
pressure computation, nested grid, landuse distributions, cloud,
fog, precipitation physics, ...more
