Statoil refinery Mongstad. Monitoring program air and precipitation 2011 - 2013. NILU OR
NILU has conducted a monitoring for Statoil in the vicinity of Mongstad refinery. There were two stations, Sande and Sundsbø. Mean concentrations of NOx at Sande and Sundsbø were 3,43 og 1,42 µg/m3 respectively, i.e. low values. Maximum hourly mean concentrations of NO2 were 49,9 µg/m3 and 36,4 µg/m3 (Sande and Sundsbø). Concerning O3 annual mean concentration in 2012 at Sande was 64,6 µg/m3, maximum hourly mean was 145,4 µg/m3. SO2 showed very low values (maximum hourly mean 7,24 µg/m3). For PM10 annual mean values were 16,8 µg/m3 and 7,4 µg/m3 respectively (Sande and Sundsbø), maximum daily mean values in 2012 were 60,9 µg/m3 and 29,1 µg/m3. BTEX (benzene, toluene, etylbenzene and xylene) showed low values. Sampling of PAH in air was performed every 6. day. Maximum concentration of 16 EPA PAH was 6,96 ng/m3, maximum benzo(a)pyren (BaP) was 0,050 ng/m3. PAH in precipitation showed maximum value of 42,7 ng/L, maksimum BaP in prcipitation was 0,679 ng/L.

The effect of selected amines on the corrosion of carbon steel and copper was investigated in the laboratory and in the field. The steel and copper samples were exposed to loads of the amines in the laboratory, representing possible 10 years maximum real exposure due to emission from a CO2 capturing plant, and to higher doses in the laboratory and in the field. No effect on the corrosion rate for steel was detected for the application of a possible 10 years real maximum dose of the amines in the laboratory as compared to blanks. Application of 700 times higher doses of amines in the laboratory was observed to give anodic protection, and thus reduced corrosion, of steel samples, but to dissolve the surface of a copper sample. The anodic protection was due to the formation of an amine surface film that protected the sample form oxidation. The dissolution of copper was probably due to formation of a copper-amine complex at high pH. A slight increase in corrosion was observed for samples that were exposed to the equivalent of possible 65 years maximum real exposure of amines in the field. This may be explained by freezing point depression and increased time of wetness of the sample surfaces due to accumulation of the amine solute on the sample surfaces in the season with frost.

The nikkel smelters in NW Russia close to the Norwegian border emits large quantities of sulphur dioxide (SO2) and heavy metals. These emissions lead to enhanced concentrations of environmental pollutants in the border areas, also at the Norwegian side of the border. This report is part of the national environmental monitoring program and includes air quality monitoring, precipitation chemistry and meteorology.

Air quality near E6 at Jessheim. NILU OR
NILU has assesed air quality at a proposed site for a hospital close to E6 at Jessheim. Based upon traffic volume, emission factors and local meteorology, concentrations of NO2 and PM10 have been modelled. The results have been compared to 'Guidelines for air quality in area planning' and the 'Red' and 'Yellow' air quality areas have been presented on a map.

Measurement of volcanic ash in Norwegian air space. WP 1.4.2 Improved detection of ash clouds. NILU OR
Water and ice clouds and temperature conditions may often influence the detection of volcanic ash affected pixels in infrared satellite images. Several methods are available for the detection of ash clouds in SEVIRI images. Manual adjustments to the methods are often needed for a given ash situation. The report describes various methods for detection of ash affected pixels. A quantitative comparison of the methods is made based on synthetic SEVIRI images from the 2010 Eyafjallajokull eruption.

Background concentrations in Norway - Temporal averaging and uncertainty assessment. NILU OR
A system for providing approximate spatial and temporal estimates of the surface background concentrations of PM10 , PM2.5, NO2 , and O3 for a typical year in Norway has been established at NILU in recent years. In 2013, the system was further improved and expanded by carrying out two main tasks: Firstly the spatial component of the system was extended from previously a single year to a 3-year average, thus decreasing the impact of inter-annual variability. Secondly, a preliminary validation of the background estimates was carried out and an approximate uncertainty was calculated for four species in the dataset and is now communicated to the user on the project website. The validation results indicate that overall the average estimated concentrations follow the average observed concentration fairly well. This is particularly true for PM10 and PM2.5. The averaged estimates for O3 and NO2 also follow the averaged observations relatively closely, although NO2 is clearly underestimated at all four validation stations. In terms of quantitative uncertainty estimates for the hourly estimates at the level of individual species, O3 is the parameter which was found to have the lowest uncertainty of all four species. While the median absolute uncertainty for hourly O3 estimates was found to be 18.7 ¿g m-3, the median relative uncertainty was only 33.8 %. Both PM10 and PM2.5 had significantly higher uncertainties, with a median relative uncertainty for the hourly estimates of 90 % and 88 %, respectively. Finally, the hourly estimates for NO2 also showed quite high relative uncertainties with a value of 73 %.

For retrieval of ash mass loading from infrared satellite measurements, estimates of the ash cloud temperature and the surface temperature are required. The ash cloud temperature and surface temperature may be taken from satellite measurements, weather model forecast, or deduced by satellite retrievals.
The report describes various methods to estimate the ash cloud temperatue and surface temperature. The impact of varying cloud temperature and surface temperature on the signal measured by an IR-sensor in space is investigated.

The Bangladesh Air Pollution Management (BAPMAN) project is an institutional-building project where NILU lends the necessary Air Quality Management (AQM) tools and associated training to the Clean Air and Sustainable Environment (CASE) program at the Department of Environment (DoE). Mission 9 of the BAPMAN project occurred in Dhaka from 19-24 October 2013 where the target of the mission was to finalize Task 2 training (CAMS QA/QC), continue Task 1 training (AirQUIS emission inventory), and to upgrade the data retrieval interface for the AirQUIS server (Task 3).

Satellite-based measurements of volcanic ash give the total amount of volcanic ash per area, typically in units of grams of volcanic ash per square meter. To convert this to concentration the vertical thickness of the ash cloud is needed. The ash cloud thickness is not available from passive remote sensors, e.g. IR-sensors, but may be obtained from ground- and space-based lidars. Dispersion models will also provide information of the ash thickness.
This report gives an overview of volcanic ash cloud thickness as observed by space, aircraft and ground-based lidars. Also, ash cloud thickness as simulated by the Flexpart particle dispersion model is analysed. The impact of varying cloud thickness on the signal measured by IR-sensor in space is investigated. Focus is on the Eyjafjallajokull 2010 eruption for which a unique wealth of data are available.

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.
