We present the development of ANISORROPIA, the discrete adjoint of the ISORROPIA thermodynamic equilibrium model that treats the Na +-SO 4 2- HSO 4 -NH 4 +-NO 3 -Cl -H 2O aerosol system, and we demonstrate its sensitivity analysis capabilities. ANISORROPIA ...
We present a review of Microsystems-based technologies for the miniaturization of gas detection systems with a focus on air quality monitoring. On one hand, compared to sensors technologies, an approach based on microanalytical instruments can fulfill some ...
The pseudo-bottom-inception point related to air entrainment is located further upstream on stepped spillways than on smooth spillways, for otherwise identical conditions. Its position is relevant concerning cavitation aspects, flow losses and flow depths. ...
Two versions of the Emission Inventory (EI) are generated for the city of Bogota, Colombia. In the first version (EI-1), CORINAIR traffic emission factors (EFs) are used. In the second (EI-2), bulk traffic EF's calculated for the city, using in situ measur ...
Bogota has more than 8 million inhabitants and is the 5th biggest urban agglomeration in Latin America. It has more than one million vehicles and a large number of small industries. High levels of air pollutants are thus detected. The purpose of this work ...
Growing population, extensive use (and abuse) of the natural resources, increasing pollutants emissions in the atmosphere: these are a few obstacles (and not the least) one has to face with nowadays to ensure the sustainability of our planet in general, an ...
During the last century, urban pollution has increased with the growth of cities. Urban air quality has become a high priority as it is directly linked to concerns such as human exposure and health. The present work is dedicated to urban air quality modeli ...
The links between air pollution gas phase chem., aerosol chem. processes, and solar radiation are calcd. to improve air quality models. Air quality models are used to simulate pollutant content of the city plumes such as for Los Angeles. ...
An episode selection procedure was developed and applied to select sets of days representing characteristic meteorol. conditions leading to high ozone episodes over the Swiss Plateau. The selection procedure was applied to data extending from Jan. 1991 thr ...
With increasing evidence of adverse health effects associated with particulate matter (PM), the exposure impact of natural sources, such as forest fires, has substantial public health relevance. In addition to the threat to nearby communities, pollutants r ...
