It was noted that BOTH TEI 42i's lost their internal Mass Flow Meters.  This was not consequential as the inlet has much better Mass Flow Controllers.  

Ambient data appear valid.  

Diurnal cycles of all three species are readily apparent.  Generator operation and restarts seemed quite common this month.  No discrimination of these periods was provided.  

Multiple large (>100 ppbv) excursions noted.  Most (but not all) of these correlate with CO excursions.  They are very fast and so the NO2 values (which depend on a difference measurement) are not valid.  It is nearly impossible to discriminate these periods.  Some of these periods MAY be due to local generator emissions and the associated variability with instrument/pump restarts.
