WP 1.4.1: Visualization of modelled SEVIRI IR-scenes for quality control. NILU OR
The SEVIRI instrument produces infrared images. The report describes how the RTTOV radiative transfer model is used to simulate SEVIRI images for an ash situation.

WP 1.2 Operationalization of satellite-based volcanic ash measurements. NILU OR
Data from the SEVIRI instrument is available at NILU through EUMETCast. These data are processed at NILU to retrieve volcanic ash loading in a satellite pixel. The report describes operationalization and automatization of the data processing algorithms at NILU including how the data are made available for the Norwegian Meterological Institute.

Esso Slagen refinery - Monitoring program 2006-2011. NILU OR
NILU - Norwegian Institute for Air Research has been conducting a monitoring pogram for Esso (ExxonMobile) at Slagen refinery from 2006-2011. The program included monitoring of meteorology, SO2, PM10, BTEX and rain water chemistry. Results show that air quality standards for SO2 were exceeded in 2009, both concerning hourly mean values (29 values above 350 µg/m3), daily mean values (five values above 125 µg/m3) and annual mean (20,3 µg/m3 vs 20 µg/m3). For the other components there were no exceedence of air quality standards, except for benzene in 2009 (2,6 µg/m3 vs national target value of 2 µg/m3).

Heavy metals at Xstrata. Assessment of measured concentration level. NILU OR
NILU has done an analysis of heavy metal concentrations measured at Xstrata, Kristiansand. Through a simplified dispersion scheme, the measured concentrations have been converted to emissions. These have been compared to the reported emissions from Xstrata. The reported emissions and the measured concentrations are in agreement.

Evaluation of new data sources for improving the estimation of background concentrations in Norway. NILU OR
A previous report (OR 68/2011) described a geostatistical methodology developed for creating a consistent dataset of background concentrations of NO2, O3, PM10, and PM2.5 in Norway, that are representative of a typical year. The resulting dataset has a resolution of 0.1 degrees by 0.1 degrees and is available at hourly temporal resolution. Based on this existing methodology, this study reports on the evaluation of new data sources as a means of improving such estimates of background concentrations. The potential of satellite-derived NO2 data is evaluated for guiding the geostatistics-based spatial interpolation procedure of NO2 station data in Norway. Furthermore, the output from a high-resolution atmospheric model was tested with respect to its capability of improving the spatial and temporal characterization of background concentrations. Finally, an online web mapping system was developed to make the project results easily accessible and to provide basic data analysis and visualization routines for the public.

Air Quality in Norwegian cities. Handbook for luftkvalitet.info - administration. NILU TR
This handbook offers an introduction to the webportal admin.luftkvalitet.info developed by NILU for The Norwegian Public Roads Administration and The Climate and Pollution Agency (Klif). The modules in luftkvalitet.info - administration provides necessary tools for quality insurance and handling of air quality data in the Norwegian national measurement database.

Statoil assigned NILU - Norwegian Institute for Air Research to carry out a programme on 'Environmental monitoring of emissions to air from the Snøhvit LNG facility'. The project started on 1 February 2006. This report summarises the results of the measurement programme from 1 July 2011 to 30 June 2012. It involves the measurement of meteorological parameters on Melkøya and Fuglenesodden. Air quality parameters were measured at Fuglenesodden. Precipitation samples taken at Forsøl and Kargeneset were analysed for PAHs, inorganic ions, heavy metals and mercury. The current air quality standards are met for all compounds.
