ON OPTIMAL METEOROLOGICAL PREDICTION OF TRAJECTORIES THROUGH STOCHASTIC FLOW FIELDS
(NILU TN;3/80, Research report, 1980)The dependence of some physical processes upon environmental flow and flow prediction is approached. Procedures for obtaining sufficiently accurate prediction methods for these processes are outlined. -
On the composite response of the MLT to major sudden stratospheric warming events with elevated stratopause
(Journal article; Peer reviewed, 2016) -
On the Convergence and Capability of the Large-Eddy Simulation of Concentration Fluctuations in Passive Plumes for a Neutral Boundary Layer at Infinite Reynolds Number
(Peer reviewed; Journal article, 2020)Large-eddy simulation (LES) experiments have been performed using the Parallelized LES Model (PALM). A methodology for validating and understanding LES results for plume dispersion and concentration fluctuations in an ... -
On the interfacial roughness scale in turbulent stratified two-phase flow: 3D lattice Boltzmann numerical simulations with forced turbulence and surfactant
(Journal article; Peer reviewed, 2015) -
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 ... -
ON THE PREDICTION OF HAZARD AREA RESULTING FROM A GAS RELEASE
(NILU OR;1/81, Research report, 1981)A synthesis of hazard area prediction followinq the release of a hazardous gas cloud is developed. At a fixed risk level the predicted hazard area is estimated to depend much upon prediction errors for actual atmospheric ... -
On the Robustness of Field calibration for Smart air quality monitors
(Peer reviewed; Journal article, 2020)The robustness of field calibrated Air Quality Multi-sensors (AQM) performances to long term and/or mobile operation is still debated. Though accuracy generally exceeds the one of laboratory calibrations models, experimental ... -
On the search for an intelligible comet assay descriptor
(Journal article; Peer reviewed, 2014) -
ON THE SUITABILITY OF "BADGE" AIR SAMPLERS FOR HUMAN EXPOSURE ASSESSMENT
(NILU OR;1/82, Research report, 1982)A brief literature scan suggests that personal monitoring of human exposures to air pollutants is essential in health impact assessment. Passive personal exposure monitoring devices (PEMs) are simple, inexpensive, rugged, ... -
On the tuning of atmospheric inverse methods: comparisons with the European Tracer Experiment (ETEX) and Chernobyl datasets using the atmospheric transport model FLEXPART
(Peer reviewed; Journal article, 2020)Estimation of the temporal profile of an atmospheric release, also called the source term, is an important problem in environmental sciences. The problem can be formalized as a linear inverse problem wherein the unknown ... -
One planet: one health. A call to support the initiative on a global science–policy body on chemicals and waste
(Peer reviewed; Journal article, 2022)The chemical pollution crisis severely threatens human and environmental health globally. To tackle this challenge the establishment of an overarching international science–policy body has recently been suggested. We ... -
Online Display. User's Manual.
(NILU TR;6/96, Research report, 1996)This report is a User's Manual. It describes the Online Display software which displays and stores meteorological data online. -
Open fires in Greenland in summer 2017: transport, deposition and radiative effects of BC, OC and BrC emissions
(Journal article; Peer reviewed, 2019)Highly unusual open fires burned in western Greenland between 31 July and 21 August 2017, after a period of warm, dry and sunny weather. The fires burned on peatlands that became vulnerable to fires by permafrost thawing. ... -
Operation of an Envisat Validation Data Centre. Estec Contract No 14419/00/NL/SF. Final report.
(NILU OR; 54/2002, Research report, 2002)NILU has designed and implemented a system for organizing and presentation of ground based measurement data, and for retrieval of the same data by scientists that perform comparisons with measurements from the ENVISATsatellite. ... -
Oppdatering av klassifisering av luftforurensninger i 10 byer og tettsteder.
(NILU OR; 28/89, Research report, 1989)I 1986 ble 92 byer og tettsteder over hele landet klassifisert etter graden av luftforurensning. For ti av stedene er klassifiseringen nå oppdatert for stoffene SO2 sot og NO2 Det er dessuten beregnet hvor mange personer ... -
