Summary

Nitrogen oxides play a crucial role in the budget of tropospheric ozone (O3 ) and the formation of the hydroxyl radical. Anthropogenic activities and boreal wildfires are large sources of emissions in the atmosphere. However, the influence of the transport of these emissions on nitrogen oxides and O3 levels at hemispheric scales is not well understood, in particular due to a lack of nitrogen oxides measurements in remote regions. In order to address these deficiencies, measurements of NO, NO2 and NOy (total reactive nitrogen oxides) were made in the lower free troposphere (FT) over the central North Atlantic region (Pico Mountain station, 38°N 28°W, 2.3 km asl) from July 2002 to August 2005. These measurements reveal a well-defined [...]
