Abstract:

Goals:
This experiment is a repeat of 140724 experiment but this time with the NO2PAN monitor to quantify NO, PAN, and MPAN. The goal of this experiment is to photooxidize MPAN and capture NO3 with a-pinene, while observing secondary organic aerosol (SOA) formation through dry nucleation. MAE was added toward the end of the experiment to see if it enhanced SOA formation.

Summary:
Observations are the same as for 140724 - large SOA formation, alpha pinene was observed to capture NO3 which indicated that NO3 is product of MPAN oxidation, and MAE does not increase or otherwise alter SOA formation

Citation counts are compiled through information provided by publicly-accessible APIs according to the guidelines developed through the https://makedatacount.org/ project. If journals do not provide citation information to these publicly-accessible services, then this citation information will not be included in RDA citation counts. Additionally citations that include dataset DOIs are the only types included in these counts, so legacy citations without DOIs, references found in publication acknowledgements, or references to a related publication that describes a dataset will not be included in these counts.
