Operational Model for Atmospheric Transport and Deposition of Air Pollution/ Operacyjny Model Atmosferycznego Transportu I Depozycji Zanieczyszczeń

Abstract

An assessment of the current state of natural environment affected by air pollution, as well as, forecasts of pro-ecologic, economic and social activities are very often performed using models for atmospheric transport and deposition of air pollutants. In the present paper, we present an operational dispersion model developed at the Institute of Meteorology and Water Management in Warsaw. The basic assumptions and principles of the model are described together with the operational domain and examples of model applications. Two examples of model application are described and discussed here. The first, application is a simulation of the atmospheric transport and deposition of the radioactive isotopes released into the atmosphere during the Chernobyl Accident in 1998. The second example is related to simulation of atmospheric transport of the tracer released into the air during the ETEX experiment. These two examples and previous applications of the model showed that presented dispersion model is fully operational, not only for long term applications, but especially for emergency situations, like nuclear accidents or volcanic eruptions affecting Polish territory

Contribution of Poland to Atmospheric Nitrogen Deposition to the Baltic Sea

“…For the same year in addition to standard EMEP MSC-W model with 50-km resolution, we have also used the air pollution model developed at the Institute of Meteorology and Water Management (IMWM) in Poland (Mazur 2008; Mazur et al 2014) with better spatial resolution—14 km. The year 2013 was chosen because this was the year for which the results of IMWM model were available.…”

“…In this study, it has been used for nitrogen computations for one year, 2013, only. This model is developed at the Institute of Meteorology and Water Management in Warsaw, Poland (Mazur 2008; Mazur et al 2014). The IMWM model takes into account the same physical and chemical processes as the EMEP/MSC-W model, but the parameterizations of these processes are slightly different.…”

“…Nitrogen depositions to the Baltic Sea in the year 2013 have been calculated with the IMWM model developed at the Institute of Meteorology and Water management in Warsaw, Poland (Mazur 2008; Mazur et al 2014). Spatial distribution of annual dry deposition of oxidized nitrogen, wet deposition of oxidized nitrogen, dry deposition of reduced nitrogen, and wet deposition of reduced nitrogen from the IMWM model results for the year 2013 are shown in Fig.…”

“…However, a different model grid (0.1 × 0.1 deg) was used for 2015 (Fagerli et al 2017), which is not consistent with the grid used for the years 1995–2014 (50 km × 50 km). For one specific year, 2013, we have also compared results of the EMEP model with the results of another model developed at the Institute of Meteorology and Water Management (IMWM) in Poland (Mazur 2008, 2016; Mazur et al 2014). …”

Hypothetical Accident in Polish Nuclear Power Plant. Worst Case Scenario for Main Polish Cities

“…In the first phase, the method for finding the worst case meteorological scenario based on the trajectory analysis is described and discussed, as well as the obtained results. These results include the selection of the meteorological conditions and dates for the Eulerian dispersion model simulations [5]. In the second part of the research this model was used with meteorological scenarios (selected in the first phase) to calculate the corresponding concentration and deposition of the radioactivity over the Polish territory, in particular over the biggest Polish cities.…”
