(author), van der Gon, H.D. (author), Manders-Groot, A.M.M. (author), Raaschou-Nielsen, O. (author)The integrated model system DEHM/UBM/AirGIS, developed at Aarhus University, Department of Environmental Science, has been extended with the dynamic aerosol module M7 to account for particle number concentrations of particles with diameters below 1 μm in the atmosphere. The aim of this development is to quantify the spatial and temporal...article 2021

(author)Modelling of ambient particle number concentrations (PNC) has been implemented in the Danish air quality modelling system DEHM/UBM/AirGIS and evaluated with long-term measurements. We implemented particle dynamical processes in the regional scale model DEHM using the M7 aerosol dynamics module (presented in the accompanying article by Frohn et...article 2021

(author), TNO Fysisch en Elektronisch Laboratorium (author)The atmospheric chemistry and deposition model has been applied for calculation of nitrogen and sulphur depositions to the entire North Sea area for the year 1999. The total atmospheric nitrogen and sulphur depositions to the North Sea area were determined to 709 kton (kt) N and 551 kt S, respectively. Since the North Sea area was calculated to...article 2002

(author), TNO Fysisch en Elektronisch Laboratorium (author)The aim of the atmospheric nitrogen inputs into the coastal ecosystem (ANICE) project is to improve transport-chemistry models that estimate nitrogen deposition to the sea. To achieve this, experimental and modelling work is being conducted which aims to improve understanding of the processes involved in the chemical transformation, transport...article 2001

(author), TNO Fysisch en Elektronisch Laboratorium (author)Terrestrial inputs of nitrogen are often dominated by riverine transport, especially in the winter (Sanders et al., 1997). However, the atmospheric contribution to the total land based nitrogen input has been reported to be on the order of 30 % for the total North Sea area (North Sea Task Force, 1993). The atmospheric nitrogen load is directly...bookPart 2001
