A simple Lagrangian dispersion model applied to sulphur pollution over Europe
Eliassen, Anton; Saltbones, Jørgen (LRTAP;6/75, Research report, 1975)A simple Lagrangian dispersion model is described and applied to sulphur pollution over Europe. The model calculations are based on available SO2-emission data for Europe, and wind observations in the 850 mb surface. A ... -
Air pollution models with non-linear chemical reactions.
Hov, Øystein; Zlatev, Zahari; Berkowicz, Ruwim; Eliassen, Anton; Prahm, Lars (NILU OR; 7/88, Research report, 1988)The coupled, non-linear system of continuity equations for an air pollution model is solved numerically using finite differences, finite elements and pseudospectral methods for the advection term. The accuracy of the ... -
LITT OM UTVASKING AV SULFATPARTIKLER I LUFT VED REGNVÆR.
Eliassen, Anton (NILU TN;54/73, Research report, 1973) -
Long range transport of air pollutants as estimated by a trajectory model
Jensen, Oddvar; Eliassen, Anton; Nordø, Jack; Saltbones, Jørgen (LRTAP;9/75, Research report, 1975)Back trajectories are computed each 6 hours for a number of stations located within the boundaries of the participating OECD countries. As an air parcel moves along its trajectory sulphur dioxide is absorbed at a rate ... -
MODELLBEREGNING AV LANGTRANSPORT AV FOTOKJEMISKE OKSIDANTER TIL SØR- SKANDINAVIA OG BETYDNINGEN AV UTSLIPPSKONTROLL.
Hov, Øystein; Stordal, Frode; Eliassen, Anton (NILU OR; 10/86, Research report, 1986)Trajektoriemodellen med atmosfærekjemi utviklet ved NILU, UiO og MI (EMEP) er brukt til å beregne oksidantkonsentrasjonen i 9 ankomstpunkter i Sør-Skandinavia i perioden 26/8-14/9-1980. Beregningene viste at ozonkonsentrasjoner ... -
PHOTOCHEMICAL OXIDANT CONTROL STRATEGIES IN EUROPE: A 19 DAYS' CASE STUDY USING A LAGRANGIAN MODEL WITH CHEMISTRY.
Hov, Øystein; Stordal, Frode; Eliassen, Anton (NILU TR; 5/85, Research report, 1985)The trajectory model with atmospheric chemistry developed by NILU, University of Oslo and DNMI (EMEP) has been applied to calculate the oxidant concentration at 9 receptor points in South Scandinavia in the period 26 August ... -
Sulphur deposition patterns over Europe estimated using a Lagrangian dispersion model, concentration data and precipitation observations
Eliassen, Anton; Saltbones, Jørgen (LRTAP;21/75, Research report, 1975) -
Sulphur transport and dry deposition over Europe described by a simple Langrangian dispersion model.
Eliassen, Anton; Saltbones, Jørgen (LRTAP;22/75, Research report, 1976)A simple Lagrangian dispersion model is described and applied to sulphur pollution over Europe. The model calculations are based on available SO2-emission data for Europe, and wind observations in the 850 mb surface. A ... -
TØRRAVSETNING AV SO2 VED NØYTRAL OG STABIL SJIKTNING.
Eliassen, Anton (NILU TN;5/75, Research report, 1975) -
Wet and dry sulphur deposition patterns over Europe for the period 13.12.73-29.3.74
Eliassen, Anton; Saltbones, Jørgen (LRTAP;8/75, Research report, 1975)On days with precipitation, a relation is established between mean SO4-concentrations measured in precipitation at some LRTAP-stations and mean SO2-concentrations, calculated with an one-layer Lagrangian dispersion model. ...
