The HOTMAC/RAPTAD system is a user-friendly, cost effective way to simulate various what-if scenarios in the computer, which is impossible to do with field measurements, but necessary for planning or mitigating potential environmental catastrophes.
HOTMAC® (higher order turbulence model for atmospheric circulation) is a three-dimensional mesoscale prediction model that forecasts wind, turbulence, humidity, and atmospheric turbulence distribution over complex surface conditions.
RAPTAD® (random puff transport and diffusion) is a three-dimensional Lagrangian random puff model that is used to forecast transport and diffusion of air pollution materials over complex terrain.Features include non-hydrostatic pressure computation, nested grid, land-use distributions, cloud, fog, precipitation physics. See below for more details.
