Processing Record for this file: (Make notes here unique for this file) Loading from flight 140930a 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. Standard add again working this flight.
