Emissions inventory for Dhaka and Chittagong of pollutants PM10, PM2,5, NOx, SOx, and CO. NILU OR
The Bangladesh Air Pollution Studies (BAPS) project is being prepared for the Clean Air and Sustainability project at the Bangladesh Department of Environment (CASE/DoE). This report summarizes the results from Task 1: Emission inventories. A combined methodology of using bottom-up and top-down scaled input data has been used to populate the emission inventory for Dhaka and Chittagong. Sources of emissions of PM10, PM2.5, NOX, SOX, and CO have been investigated for the sectors Industry (including brick kilns separately), Road Traffic, non-road Traffic, Agriculture, Urban, and Fossil Fuel (energy and gas processing). The emissions inventory has been compiled in the NILU model AirQUIS, which can then process the dispersion modelling of the emissions as needed for Task 2 of this project.

Emissions, dispersion and deposition of SO2 from Nikel and Zapolyarny. A WRD-Chem model study. NILU OR
The WRF-Chem model has been applied to study two specific episodes of pollution from the Nikel and Zapolyarny facilities, the summer episode 2007 and winter 2010/11. Meteorological input data from WRF compare well with data from ECMWF. The model underestimates concentrations of SO2 in specific episodes, a possible explanation for this is that the flue gas plume is levelled out in the model, in addition little is known about the emissions. A budget for the different processes show that chemical loss and wet deposition are most important in summer time, while wet and dry deposition are most important in winter time. WRF-Chem is computational demanding and most suited to study processes and specific episodes.

This report summarizes results from a project funded by the Research Council of Norway (196191/S30). The overall goal was to better understand and predict relationships between emissions of organic chemicals of emerging concern and their levels in the environment and food-chains of the Nordic region through integrated monitoring and modeling studies. Four case studies were selected (i) cyclic volatile methyl siloxanes (cVMSs) in the Inner Oslofjord, (ii) cVMSs in the Norwegian Arctic (iii) short-chain chlorinated paraffins (SCCPs) in the Nordic environment and (iv) risk-based model screening of chemicals in commerce in the Nordic countries. We also provide a brief introduction to the key multimedia modelling tools which were used. It is our hope that these tools, targeting the behaviour of contaminants under relevant environmental and climatic conditions, may assist Nordic environmental authorities interested in understanding and managing organic contaminants.

This report presents an evaluation of the ambient air pollution concentrations in Norwegian cities and agglomerations in the last 5 years up to 2014. It includes an evaluation criteria to support a possible revision of air pollution zones and presents a detailed evaluation of the existing monitoring network for air quality with respect to different pollution zone distributions. Recommendations for updates in the existing monitoring network to comply with current air quality legislation are provided in the report.

Citi-Sense-MOB. Conceptual services design document. NILU OR
This report gives an overview of the service system design, requirements, specifications and architecture for the main products ¿ Citi-Sense-MOB Citizen Observatory Toolbox (COT), which comprises of a series of applications that support and complement each other. These include the concept for COT, service design concept and methodologies, the COT target groups, and a set of COT (e.g., data, web apps, mobile apps, maps, services, methodologies, etc.).
