MAX-DOAS shipping lane measurements

Map showing 5 MAX-DOAS Observations above a shipping lane in the German Bight. Horizontal light path lengths (UV path and ΔL) and corresponding path-averaged volume mixing ratios of NO2 are shown as colored lines and the in situ NO2 VMR as a colored dot at the location of the instrument. Magenta triangles show the ship position and course, with larger triangles for larger ships.
