Mineral dust cycle in the Multiscale Online Nonhydrostatic AtmospheRe CHemistry model (MONARCH) Version 2.0

An evaluation of the Monarch chemistry analyser

The Monarch Chemistry system, a centrifugal analyser incorporating sophisticated robotics for analytical rotor transfer and flexible software for workload scheduling, has been evaluated. The optical system is capable of monitoring absorbance, fluorescence and light scattering reactions. In addition, an ion selective electrode unit may be incorporated for the measurement of sodium, potassium and...

Vertically nested nonhydrostatic model for multiscale resolution of flows in the upper troposphere and lower stratosphere

Aspects of the dynamical core of a nonhydrostatic, deep-atmosphere, unified weather and climate-prediction model

The dynamical core, which governs the evolution of resolved fluid-dynamical processes, is a critical element of any atmospheric model. Its governing equations must include all relevant dynamical terms, and the numerical formulae used to approximate them must be accurate, stable and efficient. This is particularly so in a unified modeling environment in which the same dynamical core is used for ...

Implicit-Explicit Formulations of a Three-Dimensional Nonhydrostatic Unified Model of the Atmosphere (NUMA)

We derive an implicit-explicit (IMEX) formalism for the three-dimensional Euler equations that allow a unified representation of various nonhydrostatic flow regimes, including cloud-resolving and mesoscale (flow in a 3D Cartesian domain) as well as global regimes (flow in spherical geometries). This general IMEX formalism admits numerous types of methods including single-stage multi-step method...

Influence of Mineral Dust Aerosol on the Chemical Composition of the Atmosphere PI :

This proposal outlines a program of scientific research and educational development focused on mineral dust aerosol, atmospheric chemistry, and curricular use of satellite data. Mineral dust impacts the chemical composition of the atmosphere by providing a surface for heterogeneous chemistry, and for light scattering and absorption at photolytic wavelengths. We propose to assess the current and...
