AMBIENT PARTICLE LOSSES IN THE SK SAMPLING SYSTEM.
(NILU TR;14/83, Research report, 1983)The SK sampling system (filter mounted after sampling line and manifold) has been compared to an open-face filter holder mounted outside. The SK system undersamples ambient aerosols due to sampling line losses. Aerosol ... -

Prototyp for 2-filterprøvetaker.
(NILU TR;3/91, Research report, 1991)Stillegående luftprøvetaker med registrering av pumpet luftmengde. -
The NILU aircraft plume model: A technical description.
(NILU TR;4/99, Research report, 1999)The NILU-aircraft plume model combines the chemical and physical evolution in an aircraft plume. It describes the plume within a day after emissions. This report gives a detailed description of the plume dispersion, the ... -
PRECIPITATION CHEMISTRY AT THE NORWEGIAN BACKGROUND STATIONS, 1980.
(NILU TR; 15/84, Research report, 1984)The precipitation quality data measured in 181 at 14 Norwegian background stations is presented. The chemical composition is given as monthly and yearly values. Yearly value from the start of each station are also given. -
Ho Chi Minh City. Air Quality Monitoring Programme. Data evaluation report, 2007.
(NILU TR; 01/2008, Research report, 2008)The report presents the data availability and average concentrations for all air quality data measured in HCMC, Vietnam during 2007. The quality assessment indicated that there is a need for spare parts, which again will ... -
ON THE PREDICTION OF HAZARD AREA RESULTING FROM A GAS RELEASE
(NILU TN;1/80, Research report, 1980)The size of the predicted hazard area following the release of a hazardous gas cloud is estimated to depend more upon prediction error for actual atmospheric flow and flow parameters than upon the accuracy of the diffusion ... -
A TRACER INVESTIGATION OF POLLUTANT DISPERSION IN AN URBAN STREET CANYON.
(NILU TN;2/78, Research report, 1978) -
Spatio-temporal variability of the polar middle atmosphere. Insights from over 30 years of research satellite observations.
(NILU TR;01/2012, Research report, 2012)We discuss the insights that research satellite observations from the last 30 years have provided on the spatio-temporal variability of the polar middle atmosphere. Starting from the time of the NASA LIMS (Limb Infrared ... -
ESTIMATION OF EMISSION FACTORS OF TRACE METALS FROM OIL-FIRED POWER PLANTS
(NILU TR;2/82, Research report, 1982)The emission factors of trace metals from oil-fired power plants are estimated for different operating conditions using data for the same trace metal concentrations in the fuel. Fuel oil requirements and behaviour of trace ... -

SODAR målinger i Oslo, vinteren 1986/87.
(NILU TR;16/88, Research report, 1988)Vindfeltet over sentrum i Oslo ble målt ved hjelp av vet akustisk instrument (SODAR). De innsamlede data gir god informasjon om luftbevegelsen opp til 200 m høyde over bakken. Over 200 m høyde er informasjonsmengden liten. ... -
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 ... -
Vurdering av innføring av gassrensing på avfallsforbrenningsanlegg.
(NILU TR;8/91, Research report, 1991)NILU har på oppdrag fra Statens forurensningstilsyn utført spred ningsberegninger for å vurdere endring av luftforurensning og avstand til synlig røyk ved innføring av våt metode for gassrensing på avfallsforbren ningsanlegg. ... -
User's guide for the "KILDER" dispersion modelling system.
(NILU TR;5/92, Research report, 1992)The NILU "KILDER" system for calculating long-term concentrations from point and area sources is described, together with a user's guide for the PC-progra,s POI-KILD and ARE-KILD. -
Comparison of diffusive and active sampling methods for the determination of nitrogen dioxide in urban air.
(NILU TR; 24/96, Research report, 1996)The NO/NO,-monitor and the iodide method are compared with a diffusional sampler for the sampling and determination of nitrogen dioxide in urban air. The results for the diffusional sampler were within 20% of the two other ... -
