Short summary

Global isoprene emissions are the largest source of atmospheric non-methane hydrocarbons. Lab results show that ISOPOOH, a low-NO_x isoprene oxidation product, can decompose on instrument surfaces to form high-NO_x isoprene oxidation products, causing misinterpretation of oxidation conditions. This study investigated the potential formaldehyde artifact from ISOPOOH for the NASA ISAF instrument, and found that it does not significantly affect the accuracy of the ISAF field measurements.
