Overvåking av langtransportert forurenset luft og nedbør. Atmosfæriske tilførsler 2011. NILU OR
NILU utfører overvåking av luft- og nedbørkjemi under ulike overvåkingsprogrammer ved en rekke målesteder i Norge. Denne rapporten beskriver resultatene fra 2011, og disse er sammenlignet med tidligere år.

Air quality impact assessment, Kinyerezi, Dar Es Salaam, Tanzania. NILU OR
Concentrations of air pollutants from the 150MW Jacobsen Electro power plant planned for the Kinyerezi area near Dar Es Salaam, Tanzania has been estimated using two different dispersion models. The estimated annual average contribution to the ground level concentrations of NO2, SO2 , PM and CO is negligible compared to international and national standards. Only the highest one hour average concentrations may be of some concern.
The estimated absolute maximum hourly ground level concentrations of NO2 from the 150 MW gas fired power plant was found within about 2 to 3 km from the power plant. The maximum ground level concentration might reach 11 µg/m3 during very special meteorological conditions and wind from west.
Contributions to the ground level NO2 concentrations from the 150 MW power plant operated with Jet A1 liquid fuel is somewhat higher. It, however, never seems to exceed 32 µg/m3 (NOx as NO2) as a one hour average maximum concentration.
Over the city of Dar Es Salaam, about 15 km east of the plant site, the two plants will contribute during maximum conditions to about 12 to 20 µg/m3 NO2 .
The green house gas (GHG as CO2 equivalents) emissions will be less than 1 % of the present national emissions of GHG in Tanzania.

NORTRIP emission model user guide. NILU TR
The NORTRIP emission model has been developed at NILU, in conjunction with other Nordic institutes, to model non-exhaust traffic induced emissions. This short summary document explains how to run the NORTRIP model from the MATLAB environment or by using the executable user interface version. It also provides brief information on input files and the model architecture.
