1st EUROCARE Market Place Conference.
(NILU OR; 39/92, Research report, 1992)The 1st EUROCARE Market Place Conference took place at Lillehammer in Norway from 1st to 4th October 1991. The aims of the conference were to bring together those engaged on conservation, restoration and maintenance in ... -
A bottom-up air pollution emission inventory for Dakar.
(NILU OR;53/2010, Research report, 2010)The current report summarises the contentsof the bottom-up emission inventory developed for and by the CGQA for air pollutants in Dakar. The collection of emission data started in 2006 and continued until 2010. It has been ... -
A COMPARISON OF MEASUREMENTS WITH ISO REFERENCE AND NILU ATMOSPHERIC DUSTFALL DEPOSIT GAUGES.
(NILU TR; 9/85, Research report, 1985)Atmospheric dustfall deposit measured with the ISO reference gauge and the NILU gauge have been compared. Only water insoluble deposit was considered. The NILU gauge gave somewhat higher deposit values than the ISO gauge, ... -
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 ... -
A LITERATURE SURVEY OF METHODS FOR FRACTIONATED SUSPENDED PARTICULATE MATTER MEASUREMENT
(NILU OR;46/81, Research report, 1981)Literature review suggests the US-type dichotomous sampler (virtual impactor) as the best commercially available device for suspended particle fractionation/gravimetric analysis at this time. The size selective high volume ... -
A MATRIX APPROXIMATION TO LARGE SCALE PHOTOCHEMICAL MODEL CALCULATIONS
(NILU TR;11/83, Research report, 1983)The QSSA model for photochemical reactions in the atmosphere is simulated by a limited system of linear differential equations which can be solved analytically. This permits the use of large time-steps, and the computer ... -
A MODEL FOR HEAVY GAS DISPERSION IN THE ATMOSPHERE
(NILU OR;18/79, Research report, 1979)A simple model for the dispersion of heavy and cold gas cloud is developed. The results are not critically dependent upon coefficient variations. The predicted spread show good correspondence with data from Forton. -
A MODEL FOR LONG RANGE TRANSPORT OF SULPHUR DIOXIDE AND PARTICULATE SULPHATE IN THE ATMOSPHERE - A TECHNICAL DESCRIPTION.
(NILU OR;82/86, Research report, 1986)This report contains a documentation of a numerical model for the calculation of long range transport of sulphur dioxide and particulate sulphate. The model is eulerian with several vertical layers (at least three). The ... -
A NUMERICAL MODEL SUITABLE FOR THE SIMULATION OF A BROAD CLASS OF CIRCULATION SYSTEMS ON THE ATMOSPHERIC MESOSCALE.
(NILU TR;2/87, Research report, 1987)The report constitutes a documentation of a numerical model for the atmospherical mesoscale. The model includes a high resolution planetary boundary layer parameterication, an equation for ground surface temperature and a ... -
A PM10 intercomparison exercise in Norway.
(NILU OR;41/2007, Research report, 2007)This report presents the results from a PM10 field intercomparison exercise performed in Norway. The exercise included several sampelrs and automatic monitors as candidate instruments as well as the Andersen high volume ... -
A short introduction to the GEOmon and EBAS databases at NILU, available for the CityZen project.
(NILU TR; 03/2010, Research report, 2010)This technical report gives an overview of the data bases EBAS and GEOmon and explains how to extract data of relevance for the CityZen project. -
A simple Lagrangian dispersion model applied to sulphur pollution over Europe
(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 ... -
