Air quality in Hamar. Monitoring program December 2010 - June 2011. NILU OR
NILU has carried out monitoring of air quality in the center of Hamar from December 2010 till May 2011. The results have been compared to corresponding measurements at Lillehammer. The level of NO2 is lower and the level of PM10 is higher at Hamar, compared to Lillehammer. The limit value for number of days with PM10 above 50 µg/m3 is probably exceeded in the center of Hamar.

Monitoring of the atmospheric ozone layer and natural ultraviolet radiation. Annual report 2011. NILU OR
This is an annual report describing the activities and main results of the monitoring programme 'Monitoring of the atmospheric ozone layer and natural ultraviolet radiation' for 2011.
2011 was a year with generally low ozone values above Norway. A clear decrease in the ozone layer above Norway during the period 1979-1997 stopped after 1998 and the ozone layer above Norway seems now to have stabilized.

Calculation of dispersion and deposition, April 2010 - April 2011. NILU OR
NILU - Norwegian Institute for Air Research has calculated concentrations of NO2, SO2, and PM10 resulting from emissions from Hammerfest LNG and related shipping. Also emissions deposition of nitrogen and sulphur have been calculated. Calculations show that concentrations of NO2 may exceed the thresholds recommended by the Norwegian State Pollution Agency, but not the EU limit values nor National target values. There are no exceedances of SO2 or PM10 limit values. Calculations give a maximum yearly deposition of 14 mg N /m2 and 11 mg S /m2.
