Atmospheric Chemistry Experiment (ACE) Arctic stratospheric
[1] Solar occultation measurements recorded in the Arctic by the Atmospheric Chemistry Experiment (ACE) Fourier transform spectrometer show elevated volume mixing ratios of NO and NO2 in the upper stratosphere from mid-February to late March 2004. Mixing ratios of NO exceeded 1.3 ppmv (106 parts per...
