Processing Record for this file: (Make notes here unique for this file) Loading from flight 141001a Data taken from DMF Data in flight appear normal. Plume is prominently apparent. It has been observed that the NO/NO2 ratios do not appear reasonable at low levels (<500 pptv). There seems to be a constant artifact in the NOx channel. This makes the NO2 reported high and should not be used directly. These data are only preliminary. 14:30 - 15:05 something happened with no signal. Channel 3 flow went to zero. O3 turned off. Do not use this period. 15:10 Mo converter turned off
