Summary of work on ISECA atmospheric modelling, September 2011–12 July 2012
Djambazov, G.; Pericleous, K.; Patel, M. [s.d.]. Summary of work on ISECA atmospheric modelling, September 2011–12 July 2012. Centre for Numerical Modelling and Process Analysis, University of Greenwich: London. 5 pp.
Atmospheric Modelling was employed to highlight the effects of nutrients transported in the air and deposited in the 2Seas region that can affect the eutrophication processes examined in ISECA. Meteorological data were obtained from ECMWF(http://www.ecmwf.int) for selected periods in the near past. Emissions data for nitrogen containing gases were taken from EMEP (http://www.ceip.at) with grid resolution which matched the one of the weather data. Lagrangian Particle Dispersion (LPD) techniques (http://transport.nilu.no/flexpart) were used to compute the transport in the atmosphere and the deposition of these nutrients onto the sea and the nearby land. Preliminary results of this 'local' model show lower deposition quantities of nitrogen oxides than the corresponding quantities obtained by the EMEP 'wider region' model. As the LPD model set-up has been thoroughly verified, this suggests that significant amounts of the nitrogen nutrients arriving to the 2Seas region by air originate further away.
