Loading from flight 140922a
Data taken from NOx CPU c:\data\NOx

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.

Operator reported a dry-ice bridge in the cooler leading to less than efficient cooling of the PMTs.  Some increase in background noted, but appears inconsequential.
