He has had a central role in PNNL's global aerosol, chemistry, and climate modeling, and in modeling studies of aerosols and cloud - aerosol interactions at local and regional scales.

Within the integrated Earth system science paradigm, our major research thrusts include the physics and chemistry of aerosols, clouds and precipitation; integrating our understanding of climate, energy, and other human and natural systems through the development and application of models that span a wide range of spatial scales; and determining the impacts of and informing responses to climate and other global and regional environmental changes.

Scientists are using airborne observations of atmospheric trace gases, aerosols, and cloud properties from the North Slopes of Alaska to improve their understanding of global climate, with the goal of reducing the uncertainty in global and regional climate simulations and projections.

Aerosol - cloud interactions in regional and global climate models: Uncertainties and discrepancies between models and observations

The meeting will mainly cover the following themes, but can include other topics related to understanding and modelling the atmosphere: ● Surface drag and momentum transport: orographic drag, convective momentum transport ● Processes relevant for polar prediction: stable boundary layers, mixed - phase clouds ● Shallow and deep convection: stochasticity, scale - awareness, organization, grey zone issues ● Clouds and circulation feedbacks: boundary - layer clouds, CFMIP, cirrus ● Microphysics and aerosol - cloud interactions: microphysical observations, parameterization, process studies on aerosol - cloud interactions ● Radiation: circulation coupling; interaction between radiation and clouds ● Land - atmosphere interactions: Role of land processes (snow, soil moisture, soil temperature, and vegetation) in sub-seasonal to seasonal (S2S) prediction ● Physics - dynamics coupling: numerical methods, scale - separation and grey - zone, thermodynamic consistency ● Next generation model development: the challenge of exascale, dynamical core developments, regional refinement, super-parametrization ● High Impact and Extreme Weather: role of convective scale models; ensembles; relevant challenges for model development

Global and regional impacts of HONO on the chemical composition of clouds and aerosols.

The ENA is providing a rare, long - term data set about the response of these low clouds to changes in atmospheric greenhouse gases and aerosols — a major source of uncertainty in global and regional climate models.

Because of the combination of high absorption, a regional distribution roughly aligned with solar irradiance, and the capacity to form widespread atmospheric brown clouds in a mixture with other aerosols, emissions of black carbon are the second strongest contribution to current global warming, after carbon dioxide emissions.

Professor Slingo: Our view in the Met Office on geo - engineering activities - and we are talking principally here about solar management, so stratospheric aerosols, cloud seeding and so forth - is that we understand very well now that even the very simple forcing of the global system, which we have done through carbon dioxide, has huge regional ramifications and the same would be true with geo - engineering.

This is the first long - term regional study to confirm observations that mineral aerosols in both low and high clouds can act as kernels for precipitation to form around.

The direct and indirect radiative effects of aerosols suspended in the atmosphere above clouds (ACA) are a highly uncertain component of both regional and global climate.
