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 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 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 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 TRACER INVESTIGATION OF A LABORATORY VENTILATION SYSTEM.
(NILU TN;8/78, Research report, 1978)Several SF6 tracers tests were conducted within a laboratory-office building in order to investigate the building ventilation system. This work serves as a demonstration of how tracer techniques can be used to characterize ... -
A TRACER INVESTIGATION OF POLLUTANT DISPERSION IN AN URBAN STREET CANYON.
(NILU TN;2/78, Research report, 1978) -
A tracer study of the ventilation system in NILUs new building.
(NILU TR; 15/94, Research report, 1994)This report describes a tracer study of the ventilation system in NILU' s new building. The tracer SF6 is used to measure the air exchange in selected rooms and in two of the five ventilation subsystems in the building. ... -
AIR POLLUTION FROM FUEL COMBUSTION IN STATIONARY SOURCES
(NILU TN;11/71, Research report, 1971) -
Air pollution modelling. Sources - meteorology - air quality.
(NILU TR;4/93, Research report, 1993) -
Air pollution problems in the northern region of Fennoscandia included Kola. Proceedings from the Seminar at Svanvik, Norway, 1-3 June 1993.
(NILU TR; 14/94, Research report, 1994)Proceedings from a seminar held in Svanvik, Norway 1-3 June 1993 on Air Pollution Problems in the Northern Region of Fennoscandia included Kola. The expert group on studies of local air pollution problems under the Joint ... -
AIR QUALITY ASSESSMENT AND SURVEILLANCE PROGRAMMES.
(NILU TR; 4/85, Research report, 1985)The necessary elements in air quality and surveillance programmes are discussed. A presentation of NILUs project and experience is given in Appendices. -
Air quality databases at NILU. EBAS version 1.01.
(NILU TR; 3/95, Research report, 1995)A relational database structure has been defined to accomodate both the requirements of the EMEP immision database, the AMAP air quality database, and potential developments of these projects. The fundamental concepts of ... -
Air Quality Management Strategy Planning Tool.
(NILU TR; 4/96, Research report, 1996)A concept for development of an Air Quality Management System and planning tool is described. The system contains modules for calculating emissions, dispersion and air quality, exposure and damage, costs of damage and ... -
Air quality maps of NO2 and PM10 for the region including Stavanger, Sandnes, Randaberg and Sola (Nord-Jæren). Documentation of methodology.
(NILU TR;01/2014, Research report, 2014)This report documents the methodology used to make air quality maps of NO2 and PM10 for the region Nord-Jæren, which includes the municipalities of Stavanger, Sandnes, Randaberg and Sola. It provides support documentation ... -
Air quality measurements at NORDMEDUNIT, Umm Quasr, Iraq.
(NILU TR;6/91, Research report, 1991)The first results of air quality measurements performed by NILU in Umm Quasr, at the border of Kuwait and Iraq show high concentrations of black smoke, and rather low concentrations of so2 and PAH. -
Air quality monitoring systems and applications.
