Regional Source Quantification model for sulphur oxides in Europe
TLDR
In this article, an air quality model for estimation of emissions on a regional scale is developed using measured air concentrations and air trajectory transport calculations to determine the emissions, and the optimal emission strength is obtained by a least square approximation between measured and estimated air concentrations of pollutants.About:

Formation of sulfuric and nitric acid in the atmosphere during long-range transport
TL;DR: In this article, a simple photochemical model has been used to simulate the formation of sulfuric and nitric acid during long-range transport through the atmosphere, which has been shown to have a significant influence on the rate of formation of H 2 SO 4 : a higher emission of NOx tends to reduce the levels of OH and H 2 O 2 close to the source area.

The transfer of airborne pollutants to the Arctic region
TL;DR: In this paper, a detailed knowledge of the composition of the Arctic aerosol and its possible influence on the radiation balance is essential, and in view of the future oil exploitation activities in this region, the necessary investigations should not be delayed for too long.

Coupling of wet scavenging of sulphur to clouds in a numerical weather prediction model
TL;DR: In this paper, the description of bulk wet scavenging is coupled to clouds and precipitation in a weather prediction model, and results are shown for summer, autumn and winter episodes of regional scale wet sulphur deposition over Scandinavia.

Ozone-secondary aerosol-visibility relationships in North-West England
Ian Colbeck,Roy M. Harrison +1 more
TL;DR: In this article, the results are analyzed statistically and indicate correlation of ozone levels with both primary and secondary pollutants, consistent with tropospheric photochemical production of ozone in polluted air masses.
Journal ArticleDOI
Methods of sensitivity theory and inverse modeling for estimation of source parameters
TL;DR: This paper discusses another approach for inverse modeling, based on variational principles and adjoint equations, and applicable for Eulerian and Lagrangian models, and provides optimal estimations for objective functionals.

TL;DR: The theory of least squares and analysis of variance has been studied in the literature for a long time, see as mentioned in this paper for a review of some of the most relevant works. But the main focus of this paper is on the analysis of variance.

The oecd study of long range transport of air pollutants: Long range transport modelling
TL;DR: In this article, a Lagrangian-type model was used to quantify long range transport of sulphur over Europe on an annual basis (1974), and the estimated total amounts of dry and wet deposition within the area considered (9 M km 2 ) are about 11 Mt and 6 Mt S respectively.

Decay and transformation rates of SO2, as estimated from emission data, trajectories and measured air concentrations
Anton Eliassen,Jørgen Saltbones +1 more
TL;DR: In this article, the daily mean air concentrations of SO2 and SO4 at several OECD ground sampling sites are computed using OECD SO2-emission data for Europe, and a simple trajectory model which includes rates of decay and transformation of SO 2.
