Concentration of gas-phase NO/NOy and BrO in the boundary layer at Summit Station, Greenland

This dataset contains in-situ measured bromine monoxide (BrO), nitric oxide (NO) and total reactive nitrogen (NOy) in the boundary layer of Summit Station, Greenland, in the summers of 2010 and 2011. BrO was measured with the chemical ionization mass spectrometry (CIMS). NO/NOy was measured with chemiluminescence.
