Conclusions (for now)• very good agreement for ambient PAN
measurements, considering it’s field data• acceptable agreement for ambient PPN
measurements (might improve)• LIF measures consistently higher than sum of
individual PANs (expected?)• extra PANs that GCs and CIMS miss?• no indication of LIF counting ANs as PANs• LIF NO2 background subtraction problem?• more work has to be done to produce final data
and merge measurements together• compare MPAN, APAN, PBN
