Assessment of air quality and mitigation analysis. NILU OR
NILU - Norwegian Institute for Air Research commissioned by the Climate and Pollution Agency (KLIF) made an assessment of air quality and mitigation analysis. There is analyzed data from several cities in Norway, and there are cities of different sizes to get a broad basis for analysis. The analysis is carried through for NOx, NO2, PM10, PM2,5, SO2 and benzene. This work provides a better basis for planning further work on air quality and assessment of threshold values.

SK-1401 Mongstad. Dispersion calculations. NILU OR
Norwegian Institute for Air Research (NILU) has performed dispersion calculations of emissions to air from stack SK-1401 at Mongstad refinery. Dispersion of CO2 and SO2 is calculated and analyzed. NILU has also evaluated the calculated concentrations from a HSE point of view, including life time/degradation of the components. The calculated concentrations have been added to existing background concentrations at Mongstad and the calculated total concentrations have been compared to air quality guidelines and threshold values. The defined Worst Case emission scenario exeeds the air quality limit for hourly concentrations of SO2. An alternative emission arrangement have been calculated, and this emission scenario does not exeed the air qualyi limit.

Rotational Raman scattering (RRS) causes filling-in of absorption lines in Earth shine spectra. It is routinely accounted for in analysis of UV and visible spectra measured both by satellite and ground-based instruments. RRS is also present at longer wavelengths, however, the magnitude generally decreases with increasing wavelength due to decrease in the scattering cross section. For high-resolution spectral measurements the effect may be noticeable. Depending on the application, RRS thus needs to be quantified and possibly corrected for. Of special interest is the effect of RRS in the O2-A (759-769 nm) and O2-B (686-697 nm) bands. Here, the effect of RRS in these bands is studied for the present and future satellite instruments CarbonSat, FLEX/FLORIS, MERIS and OLCI.
