Torleif Weydahl is a senior scientist in the Department of Urban Environment and Industry and has worked at NILU since 2017. He holds a degree in mechanical engineering specializing in energy and process technology and has a doctorate from the University of Trondheim (NTNU) in modeling of turbulent mixing and reactions.
At NILU, Torleif primarily works on air quality (AQ) assessments related to requirements within Norwegian regulation and in emission permits for Norwegian municipalities and industrial companies. He conducts emission and dispersion calculations for several source sectors, including analyses and the preparation of reports and documentation. He has developed AQ assessment and action plans for several Norwegian municipalities and has led the development of NERVE, an emission model for road traffic.
Torleif contributes to the European Environment Agency’s (EEA) topic centers, focusing on reporting emissions from the industrial sector in EU and EEA member countries. He is also an experienced project manager.
Before starting at NILU, Torleif gained experience in carbon capture and storage research from SINTEF in Trondheim and in consultancy related to fire and safety at Lloyd’s Register.
Torleif Weydahl has 39 publications at NILU:

The European Topic Centre on Human Health and the Environment (ETC HE) is a Consortium of 10 partners with expertise in air quality, air pollution, industrial emissions, chemicals, noise and […]
Diffuse emissions of dust from LKAB Narvik
NILU has, on behalf of LKAB Norge AS, carried out emission and dispersion calculations for combined emissions from point sources and diffuse sources from the facility in Narvik. The purpose […]
Revision of air quality assessment for Drammen
NILU, in collaboration with Asplan Viak AS, has prepared a local air quality assessment for Drammen municipality. The project includes an assessment of air quality in Drammen through traffic calculations […]
Air quality assessment for Lørenskog municipality
The air quality assessment for Lørenskog municipality covers mapping of the air quality through traffic, emission and dispersion calculations of PM10, PM2,5 and NO2 for the present situation (2019) and […]
Revised local air quality assessment for Bergen
NILU has prepared a revised air quality assessment for Bergen. The assessment with an action plan for improved local air quality aims to ensure that pollution levels remain within the […]
Air quality assessment for Levanger municipality
NILU har utarbeidet en tiltaksutredning del I (kartlegging) for lokal luftkvalitet i Levanger. Utredningen er gjennomført på oppdrag for Levanger kommune etter anbefaling fra Miljødirektoratet. Tiltaksutredningen gjør rede for forurensningssituasjonen og […]
Model Advancements for high Spatial and TEmporal Resolution simulations of environmental toxics (SIS MASTER)
The main goal of the project is to modify and enhance NILUs existing atmospheric models to allow for improved simulation of traditional air pollutants (e.g., NO2, PM2.5, PM10) at very […]
Dispersion modeling of air pollution from Årdal Metallverk
NILU has studied the effect of aluminum production on the environment around Norwegian aluminum smelters by doing calculations and measurements since the early 1970s. In this project, surface concentrations have […]
Boliden – Diffuse emissions from unloading of zinc concentrate (Boliden)
Diffuse emissions from the unloading of zinc (Zn) concentrate in Odda, Western Norway have been quantified using an inverse modelling approach. Eleven deposition samplers were strategically placed around the plant […]
Air quality assessment for Tromsø
NILU and Urbanet analyse have prepared a revised air quality assessment for Tromsø. The action plan, including strategies and measures, aims to reduce air pollution to a level that meets […]
