Obliczenia Rozprzestrzeniania Się Pyłu Drobnego W Powietrzu Atmosferycznym Z Wykorzystaniem Dyfuzyjnych Modeli Gaussa, Robert Oleniacz, Mateusz Rzeszutek

Robert Oleniacz

The chapter presents a comparison of results of modelling concentrations of fine dust (suspended dust PM10) in the air with the use of two diffusion models: the Gaussian plume model (used commonly in Poland), and the Gaussian puff model CALPUFF (used significantly less frequently). It indicates discrepancies in obtained results of calculations for point emitters taking into consideration three dimensional options (with the following heights: 20, 40 and 60 m and diameters of respectively: 1.0, 1.5 and 2.0 m). For particular variants, errors were visualised, resulting from use of the simple Gaussian plume model in place of the advanced CALPUFF …

Early Rayleigh-Scatter Lidar Temperature Measurements From The Lower Thermosphere, Leda Sox, Vincent B. Wickwar

Leda Sox

Rayleigh-scatter lidar observations were made on many clear nights at the Atmospheric Lidar Observatory (ALO) at Utah State University (USU) from 1993 to 2004 in the altitude range 45–90 km. An upgraded facility, 66 times more sensitive, has been brought on line. It has resulted in temperature measurements with maximum altitudes that extend into new territory—the lower thermosphere. All-night temperature averages have been recorded up to an altitude of 114 km. Temperatures from each month, starting in June 2014, are presented and discussed. They are compared to each other, to the ALO-USU climatology from the original lidar, and to temperatures …

Meteorologiczne Determinanty Jakości Powietrza W Krakowie, Robert Oleniacz, Marek Bogacki, Mateusz Rzeszutek, Agata Kot

Robert Oleniacz

Air quality in the Agglomeration of Krakow is determined by many factors, which include, among others, unfavorable location and the resulting meteorological conditions unfavorable for self-cleaning of ambient air. The paper presents a few examples illustrating the impact of selected meteorological factors on some pollutant concentrations in the air in Krakow. Among these, special attention was paid to the ambient air temperature (indirectly influencing the level of air emissions from the municipal sector in the winter season) as well as the wind speed and the mixing layer height. On the basis performed analyzes were to draw conclusions on meteorological restrictions …

Midlatitude Mesospheric Temperature Anomalies During Major Ssw Events As Observed With Rayleigh-Scatter Lidar, Leda Sox, Vincent B. Wickwar, Chad Fish, Josh P. Herron

Leda Sox

While the mesospheric temperature anomalies associated with Sudden Stratospheric Warmings (SSWs) have been observed extensively in the polar regions, observations of these anomalies at midlatitudes are sparse. The original Rayleigh-scatter lidar that operated at the Atmospheric Lidar Observatory (ALO; 41.7°N, 111.8°W) in the Center for Atmospheric and Space Sciences (CASS) on the campus of Utah State University (USU) collected a very dense set of temperature data for 11 years, from 1993 through 2004. The temperatures derived from these data extended over the mesosphere, from 45 to 90 km. This work focuses on the extensive Rayleigh lidar observations made during seven …

Upgraded Alo Rayleigh Lidar System And Its Improved Gravity Wave Measurements, Leda Sox, Vincent B. Wickwar, Joshua P. Herron, Marcus J. Bingham

Leda Sox

The Rayleigh-Scatter lidar system at the Atmospheric Lidar Observatory (ALO) on the Utah State campus is currently going through a series of upgrades to significantly improve its observational abilities. A specific objective of these upgrades is to expand the altitude range over which backscattered photons can be collected. A second objective is to increase the sensitivity of the instrument to be able to analyze the raw data at finer temporal and/or spatial resolutions. By measuring relative densities, the system will be able to produce absolute temperatures and relative density perturbations, which illustrate gravity wave structures. Gravity wave studies will significantly …

Results From An Extremely Sensitive Rayleigh-Scatter Lidar, Leda Sox, Vincent B. Wickwar

Leda Sox

Rayleigh-Scatter lidar systems effectively use remote sensing techniques to continuously measure atmospheric regions, such as the mesosphere (45-100km) where in situ measurements are rarely possible. The Rayleigh lidar located at the Atmospheric Lidar Observatory (ALO) on the Utah State campus is currently undergoing upgrades to make it the most sensitive of its kind. Here, the important components of these upgrades and how they will effect the study of a particular atmospheric phenomena, atmospheric gravity waves, will be discussed. We will also summarize what has been done to the system during this year to bring us to the threshold of initial …

Observations With The Most Sensitive Rayleigh-Scatter Lidar, Leda Sox, Vincent B. Wickwar, Joshua P. Herron, Marcus J. Bingham

Leda Sox

The mesosphere is the most unexplored region of the atmosphere. Its altitude range of 50-85 km lies in between the reaches of data collecting instruments like weather balloons and satellites. For this reason, remote sensing systems, such as lidar, which are able to employ ground-based instruments to make extensive measurements in this difficult to detect region. The Rayleigh-scatter lidar at USU is currently being redeveloped to be the most powerful and sensitive of its kind. This type of lidar exploits light and particle interactions, like those that account for the blue color of the sky, to make relative density and …

Satellite- And Ground-Based Co Total Column Observations Over 2010 Russian Fires: Accuracy Of Top-Down Estimates Based On Thermal Ir Satellite Data, Leonid Yurganov

Leonid Yurganov

CO total column data are presented from three space sounders and two ground-based spectrometers in Moscow and its suburbs during the forest and peat fires that occurred in Central Russia in July–August 2010. Also presented are ground-based in situ CO measurements. The Moscow area was strongly impacted by the CO plume from these fires. Concurrent satellite- and ground-based observa- tions were used to quantify the errors of CO top-down emis- sion estimates. On certain days, CO total columns retrieved from the data of the space-based sounders were 2–3 times less than those obtained from the ground-based sun-tracking spectrometers. The depth …

Ocena Oddziaływania Na Środowisko Instalacji Spalania Odpadów – Wybrane Problemy, Robert Oleniacz

Robert Oleniacz

The paper presents some problems related to the environmental impact of waste incineration plants with particular emphasis on the impact on air quality and the assessment of this impact carried out for newly built incinerators. Methodology for the calculation of emissions for new plants based on emission standards was proposed. It has been shown that waste incineration plants complying with emission limit values to a negligible extent affect the air quality, especially in the case of units with small capacity.

In the case of polychlorinated dibenzo-p-dioxins and dibenzofurans, due to lack of permissible levels in the air, it was found …

Robert Oleniacz

Assessment of the state of air pollution in the urban area is a difficult and complex task. Depending on the method of assessment the procedure requires a comprehensive research and calculations of air emissions from all sources occurring in the area and the use of atmospheric dispersion models or large-scale implementation of direct measurements of air pollutant concentrations. Both of these methods may also be applied simultaneously to their mutual verification.

The article presents the results of such a comprehensive assessment of air pollution on the example of the city of Nowy Sacz (Poland). This involved determining the emissions of …
