    The Sensitivity of the December New York Mixed Precipitation Event to Initial Condition and Microphysics Uncertainty. WRF Model Simulations of Orographically-Forced Mesoscale Turbulence in Stable Marine Boundary Layers. Analyzing the Effects of Urbanization on Regional Climate in the Chicago Metropolitan Area. Kristopher E. Rand. Amazon floodplain ecosystems include open water and intermittent flood forest and agricultural systems with different water types. They are a significant natural source of methane (CH4) in the tropics. When soils are flooded and become anoxic, CH4 is produced by methanogenesis, while microbially mediated aerobic and anaerobic oxidation of CH4 serves as the primary biological Author: Dayane Juliate Barros, Marília de Souza Bento, Murilo de Souza Ferreira, Janaina Braga do Carmo, Rog.

    Kearns SK, Mavin TJ, Hodge S. Competency-based Education in Aviation: Exploring Alternate Training e Publishing, Ltd.; Sensitivity studies with a regional atmospheric model reveal that the sharpness of the SST gradient impacts the intensity of the atmospheric response to mesoscale current features (Tanimoto et al. ), with simulation of both the pressure trough and ageostrophic winds requiring adequate resolution of the SST front in the model boundary Cited by: 1.

    Current developments in air pollution modelling are explored as a series of contributions from researchers at the forefront of their field. This newest contribution on air pollution modelling and its application is focused on local, urban, regional and intercontinental modelling; data assimilation and air quality forecasting; model assessment and evaluation; aerosol transformation. Regional climate conditions, in addition to terrain and soil type, determine which fuels are dominant in a specific area. Weather and climate affect fuel moisture content. Finally, burning, or combustion, is an exothermic chemical reaction between a fuel and an oxidant. In wildland fires the oxidant is atmospheric : Sue Ellen Haupt, Branko Kosovic, Scott W. McIntosh, Fei Chen, Kathleen Miller, Marshall Shepherd, Ma.

An adjoint model to STEM-2K3 has been developed for sensitivity studies and optimal estimation of model parameters such as emissions and initial conditions (Daescu and Carmichael, ;Hakami et.

In order to investigate the sensitivity of ozone concentrations to future climate variations, a regional oxidant model was applied for future climate Author: Eliso Kvavadze.

The chemical transport model used in this model is based on the Eulerian RADM (Regional Acid Deposition Model) model (Chang et al., ), which was adapted from North American to European conditions (Hass et al., ). EURAD is a 3-dimensional Eulerian model used in Europe to predict air pollution episodes, trends, and assess pollutant Cited by: U.S.

Although the magnitude of climate change that will occur this century is uncertain, all climate models indicate that the planet will warm.

The suite of global climate models deployed in IPCC (c) report a mean climate sensitivity 1 of °C, with a standard deviation of °C (IPCC, c, Table ); this indicates broad agreement, with some scatter, about the effects of.

X and VOC emissions as sensitivity parameters for O 3 formation; and NO X, SO 2, VOC, EC, OC, and SO 4 emissions as sensitivity parameters for PM formation. The Community Multiscale Air Quality Model (CMAQ) was used to estimate the concentrations and sensitivities of air pollutants in 36 36 km grid cells across the continental United States.

This study investigated the sensitivity of nitrate aerosols to vehicular emissions in urban streets using a coupled computational fluid dynamics (CFD)–chemistry model. Nitrate concentrations were highest at the street surface level following NH3 emissions from vehicles, indicating that ammonium nitrate formation occurs under NH3-limited conditions in street : Minjoong J.

Kim. Air Pollution and Global Warming is exceptionally well-written and presented. This is an ideal text to introduce students to the chemistry and physics of Earth's atmosphere. This accessible textbook provides a practical understanding of chemistry and physics applied to atmospheric science topics, and to the nature, causes and consequences of Cited by: The climate has changed in recent decades with the main sign being an increase in global mean temperature.

The multi-model ensembles in both the 4th and the recent 5th Intergovernmental Panel on Climate Change (IPCC) Assessment Report (AR4 and AR5) project an increase in the global mean temperature in the range of 1–6 °C by the end of the 21st century, relative to pre Cited by: 4.

Gaussian process emulation techniques have been used with the Community Multiscale Air Quality model, simulating the effects of input uncertainties on ozone and NO2 output, to allow robust global sensitivity analysis (SA). A screening process ranked the effect of perturbations in inputs, isolating the 30 most influential from emissions, boundary conditions (BCs), and Cited by: 6.

NARCCAP is a suite of climate data from several Global Climate Model–Regional Climate Model pairs built on the A2 emissions scenario of the Intergovernmental Panel on Climate Change (IPCC), a trajectory that most closely mirrors current global greenhouse gas emissions trends [72,73].

The model calculates the emissions, such as CO 2, nitrogen oxides (NOx), sulfur oxides (SOx), and volatile organic compounds, and their impacts on human health Cited by: 1.

For assessment of Class I ambient impacts, under the proposed Guideline, there will not a preferred model for distances beyond 50 km.

Typically, a Lagrangian model is the type of model appropriate to use for these screening assessments; however, applicants should establish approaches (models and modeling parameters) on a case-by-case basis in.
