An experimental and modeling study of the photochemical reactivity of heatset printing oils : project summary by William P. L Carter( Book )

3 editions published in 1987 in English and held by 83 WorldCat member libraries worldwide

A series of environmental chamber experiments and computer model simulations were carried out to assess the atmospheric ozone formation potential of the representative heatset printing oils Magie-47 and Magie-470 relative to that of ethane. n-Pentadecane, a representative major constituent of these oils, was also studied. The results showed that n-pentadecane and the printing oils tend to slow down the initial rate of ozone formation in NOx- air irradiations, but they also caused higher final ozone yields in some surrogate-NOx-air experiments. The results of these experiments were used to test current models for the reactivities of ethane and n-pentadecane. The model predictions fit the results of most of the experiments within the experimental uncertainty, though some discrepancies were observed. It is unclear whether the discrepancies are due to problems with the mechanism or to experimental difficulties. The model was used to estimate the reactivities of ethane and n-pentadecane for several idealized model scenarios representing urban air pollution episodes. The predicted atmospheric reactivities of n-pentadecane and the printing oils relative to ethane were found to be highly dependent on the conditions of the model scenario. Thus, decisions on whether regulation of emissions of printing oils is beneficial in reducing atmospheric ozone must take into account the range of conditions of the airsheds into which they are emitted

Parametric methodologies of cloud vertical transport for acid deposition models : project summary by Fred M Vukovich( Book )

3 editions published in 1988 in English and held by 82 WorldCat member libraries worldwide

A CUmulus VENTing (CUVENT) cloud module has been developed that calculates the vertical flux of mass from the boundary layer to the cloud layer by an ensemble of nonprecipitating subgrid-scale air mass clouds. This model will be integrated into the Regional Acid Deposition Model (RADM) and will serve to establish the effect of cloud venting for the RADM. In the initial phase of this research project, the basic cloud venting algorithm was established. CUVENT used the cloud model that was established by Ritter and Stedman (1985) to calculate the vertical transport of mass due to the ensemble of nonprecipitating air mass convective clouds. The major effort of the first phase of this research project was to design an optimal parameterization scheme for the cloud model so that it may be incorporated in the RADM. This parameterization scheme used basic meteorological data such as pressure, temperature, humidity, surface heat flux, etc., to predict the convective cloud amount at cloud base and cloud distribution parameters. The various models that made up this scheme were developed using data obtained during the VENTEX field program

Evaluation and assessment of UNAMAP : project summary by R. Ernest Baumann( Book )

3 editions published in 1988 in English and held by 81 WorldCat member libraries worldwide

The Evaluation and Assessment of UNAMAP is a study to determine how best to Improve the usefulness and availability of the UNAMAP air pollution dispersion models. The study consists of a technology assessment, data collection and analysis, and specific improvements contained in an implementation plan. The analysis indicates that improvements to UNAMAP are needed in the areas of. (1) model accuracy, (2) model documentation, (3) user support, (4) data collection, (5) data input, and (6) computer compatibility. The study includes the development of an improvement plan which Is based on a strategy that is consistent with the long-term objectives for UNAMAP. This strategic framework guides the implementation of improvements and strikes a balance between the goals of advancing dispersion modeling research and transferring technology to the public. Included In the plan is a set of ten specific recommended improvements

Investigation of analyzer problems in the measurement of NOx from methanol vehicles : project summary by Peter A Gabele( Book )

2 editions published in 1988 in English and held by 80 WorldCat member libraries worldwide

This study was conducted to investigate the extent and source of irregularities related to the measurement of NOx emissions for methanol cars. Corrective measures were also explored. It was observed that NOx chemiluminescent analyzers respond to methanol and formaldehyde after being exposed to high concentrations of methanol and formaldehyde over extended periods. This response can cause significant errors in the measurement of NOx from methanol cars which have inherently elevated concentrations of exhaust methanol and formaldehyde. The most effective way of eliminating the spurious response is to clean the analyzer's reaction chamber regularly when testing vehicles which are being operated on methanol fuels
