27 1001 Weinheimer, A. J.; Walega, J. G.; Ridley, B. A. National Center for Atmospheric Research DC-8 in situ NO2, NO, NOy, O3 AASE II 1 1 1992 03 20 1993 07 14 60.0 Time (seconds past 0 UT of flight day in line 7) 1 1.0 99999.9 NO (pptv) 0 12 For the 4 channels of the instrument (one reported in this file), counts are accumulated and recorded over common 2-second intervals. O3 and NOy are reduced and reported to the archive for these 2-second intervals. The time archived is the start time of the 2-second interval. NO and NO2 are reduced at 2 seconds, then averaged and reported for 1-minute intervals. For these, the archived time (an even minute) is the center time of the 1-minute averaging interval. At typical altitudes, the residence time of air in the inlet system, prior to actual sampling, is 0.1 to 0.3 seconds, except for the NO2 channel which imposes an additional 4-5 seconds residence time. The NO2 data have been shifted an even 4 seconds to accommodate this.
