A DISPERSION MODEL FOR INTERREGIONAL AIR POLLUTION PROBLEMS
(NILU TN;1/81, Research report, 1981)The time variation in concentration in three levels is considered by describing: a) advection, b) vertical exchange, c) horizontal diffusion, d) chemical reactions, e) emission from natural and antropogenic sources. Dry ... -

Research and development within the local air pollution group at NILU. Annual report 1989.
(NILU TR;6/90, Research report, 1990)The report summarizes some of the research and devleopment conducted by the local air pollution group at NILU during 1989. A major pa rt of this work was linked to air pollution modelling. Models for various kinds of ... -
SPREDNINGSFORSØK MED SF6 OG CBRF3 FOR Å STUDERE RELATIVE FORURENSNINGSBIDRAG FRA OLJEFYRING OG BILTRAFIKK.
(NILU TR;9/86, Research report, 1986)Rapporten beskriver spredningsforsøk med SF6 og CBrF3 på Lillestrøm og i Oslo. SF6 og CBrF3 er sluppet henholdsvis gjennom skorstein og ved bakken for å simulere spredning fra oljefyring og biltrafikk. Resultatene indikerer ... -
The "KILDER" air pollution modelling system, version 2.0.
(NILU TR; 12/96, Research report, 1996)The KILDER Air Pollution Modelling System is a system of small PC-programs for calculation of long-term emission, dispersion, concentration and exposure from different source categories. The KILDER system may be divided ... -
THE APPLICATION OF GAUSSIAN MODELS AT NILU
(NILU TN;11/80, Research report, 1980)The report contains the basics for the use of Gaussian type dispersion models at NILU; dispersion parameters, wind profile, plume rise deposition and possible modifications. -
THE INFLUENCE OF CAR SPEED ON DISPERSION OF EXHAUST GASES.
(NILU TR;6/86, Research report, 1986)Dispersion of exhaust gases by an open road is mapped in seven tracer experiments. Two cars emitting SF6 and CBrF were driven with different speed emitting one tracer component each. The dispersion by the road increased ... -
