Based upon the Colorado state University's Regional Atmospheric Modeling System (RAMS) we have developed a new model called AERO-RAMS that is specifically designed for aerosol studies. This is a valuable tool for studying aerosol transport, particulate matter air quality and radiative processes in a a coupled manner. This model successfully simulates smoke transport from biomass burning events and dust transport as well. New additions include aerosol chemistry, aerosol-cloud interaction interfaces and capabilities for studying aerosol-land cover interactions.

In addition to all capabilities that RAMS has, AERO-RAMS has several new features.
1) A four stream radiative transfer code with specific aerosol models
2) Injection heights for fires based on satellite and fire intensities
3) Capabilities for assimilating fires and emission
4) Capabilities for assimilating satellite aerosol optical depths
5) New capabilities for addressing aerosol-cloud interactions
6) Aerosol chemistry
7) New features for studying aerosol and land cover interactions.
8) Near real time capabilities for forecasting smoke emissions and transport.
