Norwegian Institute for Air Research
The Norwegian Institute for Air Research is involved in a wide range of applied research activities relating to air quality. Of most relevance to UncertWeb are the activities concerning urban scale air quality modelling and the development and application of data assimilation methods. Currently NILU carries out air quality forecasts for a number of Norwegian cities and provides near real time access to air quality monitoring data.
Bruce Denby
Dr Bruce Rolstad Denby is a senior researcher at the Norwegian Institute for Air Research (NILU) and is leader for work package 6 in UncertWeb. He is chiefly involved in air quality modelling and assessment, source apportionment, data assimilation and spatial statistical activities. He is interested in the question of uncertainty in air quality modelling and promotes its estimation and its communication actively.
William Lahoz
Dr William Lahoz is a Senior Scientist at NILU, leading the land data assimilation (DA) activity as well as being an active participant in the chemical DA activity. He was previously the DARC (Data Assimilation Research Centre) Deputy Director and Principal Research Fellow at the University of Reading (2002-2007). Dr Lahoz has 20+ years. of Earth observation experience, including NASA, ESA missions. He has lead prestigious EU and ESA projects: DARE, SWIFT, COST-723, ASSET. He is an organiser and lecturer of 6 international Earth observation Summer Schools. He has written over 45 peer-reviewed publications and. co-edited a DA book. Dr Lahoz is an editor for Atmospheric Chemistry and Physics.
Sam-Erik Walker
Sam-Erik Walker is a research scientist at the Norwegian Institute for Air Research (NILU) and has a M.Sc. in Statistics, and a B.Sc. in Computer Science, from the Univ. of Oslo. In the UncertWeb project he is working mainly with setting up the probabilistic air pollution forecasting system for Oslo as part of work package 6. He has more than 20 years of experience in developing and applying air pollution models for cities and urban areas and in using various statistical techniques (Kriging, Time series, Bayesian) for analysing uncertainty in observations and models and in combining them using methods of data assimilation (ensemble Kalman and particle filtering). Is the author of several of the present models at NILU, including the urban air pollution dispersion model EPISODE which is to be used in UncertWeb. Has been involved in EU 6th FP project Air4EU, where the aim was optimal assessment of air pollution in Europe, at local, urban and regional scales, using data assimilation, and was responsible for the data assimilation part of that project.
