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).

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 %.

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.
