Clouds, Aerosol, & Climate: Models & Other Methods

Models

A variety of models are used to conduct Clouds, Aerosol, & Climate research.

Parcel model

An adiabatic cloud parcel model that includes size-resolved microphysics and gas and aqueous phase chemistry. Aerosol/cloud droplets are resolved in size categories on a moving grid.

Large Eddy model

The System for Atmospheric Modeling (SAM) in large eddy simulation (LES) mode.

• Aerosol-Cloud interactions in a coupled dynamical model to study boundary layer cloud systems
• Microphysics options include Lagrangian particle, two-moment bin, and 2-moment bulk schemes

Regional

The System for Atmospheric Modeling (SAM) using the Framework for Improvement by Vertical Enhacement (FIVE) and a Simplified High Order Closure (SHOC).

• Multiple applications including a large range of scale interactions
• Subgrid scale (SGS) represented by Simplified High Order Closure (SHOC)
• Adaptive Vertical Mesh (Framework for Improvement by Vertical Enhancement; FIVE)
• 2D Hadley Cell simulations as a framework for testing model physics

Conceptual

• Heuristic models that simulate parts of the complex atmospheric system using a dynamical systems approach
• Self organization and emergence in complex systems

Other Methods

Other methods used to conduct Clouds, Aerosol, & Climate research.

Machine Learning

Machine Learning to relate cloud system properties to important meteorological variables.

Statistical Emulators

Statistical Emulators that capture the essence of specific outputs of our Large Eddy Simulations in terms of key input variables.
