Abstract:

Goals:
Measure the background concentrations created by exposing the bag to OH. Sample ISOPN pillow bags. Interested mainly in:
-what signals do the instruments see with no added VOC.
-which instruments observe signal from the ISOPN, and is their response linear to different ISOPN concentrations.

Summary:
Today we successfully ran a blank experiment (H2O2 added, no added VOC) in the high NOx bag. Instruments took turns coming off the blank experiment to sample pillow bag standards of the 4-OH, 3-nitrate isoprene hydroxynitrate provided by the Cohen and Shepson groups. The Cohen group bag was 13 ppb and the 3 Shepson bags were 47 ppt, 103 ppt, and 283 ppt.

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.
