TL;DR: A sensitivity analysis targeted on the 'reemission' output variable was conducted, including soil properties, partition coefficients and meteorological conditions, to identify the key parameters in reemission modeling and their effect on global modeling uncertainty.

TL;DR: In this article, a chemical scheme devoted to mercury transformations in the atmosphere was implemented into the Polyphemus air quality system, which was then used to perform simulations for 2008 in two domains, namely over Europe and over Poland.

TL;DR: In this article, two advanced models that respectively simulate the transport of heavy metals in the atmosphere at continental and regional scale, as well as the transfer of contaminants in the air-soil-plant system, were used to study the potential accumulation of lead and cadmium in vegetables in a French region submitted to global and local industrial releases.

TL;DR: A posteriori distributions meant to identify the origin of the release, to assess the source term, to quantify the uncertainties associated to the observations and the model, as well as densities of the weights of the perturbed ensemble, are presented.

TL;DR: A multitemporal methodology to retrieve aerosol type, to map the aerosol concentration, and to quantify mass flow rate from airborne hyperspectral data is described in this paper, which is in a good agreement with in situ stack measurements and modeling.
