ESTIMATES OF THE EFFECT OF LOCAL PRECURSOR CONTROL ON THE AMBIENT OZONE CONCENTRATION IN OSLO
(NILU TR;8/82, Research report, 1982)The "EKMA Model" (Empirical kinetic Modeling Approach) has been used to calculate changes in the ambient ozone concentration downwind of Oslo (60 N) for various assumptions of local emission control and transported ozone. ... -
Estimating methane emissions in the Arctic nations using surface observations from 2008 to 2019
(Peer reviewed; Journal article, 2023)The Arctic is a critical region in terms of global warming. Environmental changes are already progressing steadily in high northern latitudes, whereby, among other effects, a high potential for enhanced methane (CH4) ... -
Estimating stratospheric polar vortex strength using ambient ocean-generated infrasound and stochastics-based machine learning
(Peer reviewed; Journal article, 2024)There are sparse opportunities for direct measurement of upper stratospheric winds, yet improving their representation in subseasonal-to-seasonal prediction models can have significant benefits. There is solid evidence ... -
Estimating Time-Varying PCB Exposures Using Person-SpecificPredictions to Supplement Measured Values: A Comparison ofObserved and Predicted Values in Two Cohorts of NorwegianWomen
(Journal article; Peer reviewed, 2015)Background: Studies on health effects of polychlorinated biphenyls (PCBs) call for an understanding of past and present human exposure. Time-resolved mechanistic models may supplement information on concentrations in ... -
Estimating volcanic ash emissions using retrieved satellite ash columns and inverse ash transport modelling using VolcanicAshInversion v1.2.1, within the operational eEMEP volcanic plume forecasting system (version rv4_17)
(Peer reviewed; Journal article, 2024)Accurate modeling of ash clouds from volcanic eruptions requires knowledge about the eruption source parameters including eruption onset, duration, mass eruption rates, particle size distribution, and vertical-emission ... -
Estimation of Damage Cost to Building Façades per kilo Emission of Air Pollution in Norway
(Peer reviewed; Journal article, 2020)This work reports marginal damage costs to façades due to air pollution exposure estimated “bottom up,” for Norway and Oslo (Norway) by the use of exposure response functions (ERFs) and impact pathway analysis from the ... -
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 ... -
Estimation of the atmospheric hydroxyl radical oxidative capacity using multiple hydrofluorocarbons (HFCs)
(Peer reviewed; Journal article, 2024)The hydroxyl radical (OH) largely determines the atmosphere's oxidative capacity and, thus, the lifetimes of numerous trace gases, including methane (CH4). Hitherto, observation-based approaches for estimating the atmospheric ... -
Estimation of the historical dry deposition of air pollution indoors to the monumental paintings by Edvard Munch in the University Aula, in Oslo, Norway
(Peer reviewed; Journal article, 2022)The historical (1835–2020) deposition of major air pollutants (SO2, NOx, O3 and PM2.5) indoors, as represented by the monumental Edvard Munch paintings (c. 220 m2) installed in 1916 in the Oslo University Aula in Norway, ... -
ESTIMATION OF THE SPATIAL DISTRIBUTION OF THE TRACE ELEMENT EMISSION FROM CONVENTIAL THERMAL POWER PLANTS IN EUROPE AND TURKEY WITHIN THE EMEP GRID
(NILU TR; 5/82, Research report, 1982)In the report the spatial distribution of the trace element emission from conventional thermal power plants in Europe is estimated, using emission factors of trace metals from conventional power plants and data on net ... -
ESTIMATION OF TIMESERIE MODELS FOR HORIZONTAL WIND REPRESENTATIVE FOR THE NORWEGIAN WEST COAST
(NILU OR;38/80, Research report, 1980)Timeseries of horizontal wind samples at intervals of Δt = 5 min are analyzed. Power spectra are estimated via autoregressive model fitting. Akaike's identification procedure is used. -
