It has been observed that the NO/NO2 ratios do not appear reasonable at low levels (<500 pptv). The zero on the NO channel appears erroneously high. This affects both the NO and the NO2 results at low values. These data are only preliminary. NOx channel offset appears very consistent and will be subtracted later.
