The Korea United States-Air Quality (KORUS-AQ) mission was a joint field study between NASA and the Republic of Korea that assessed air quality across urban, rural, and coastal South Korea. We used observations from aircraft, ground sites, ships, and satellites to test air quality models and remote sensing methods. Our findings will help develop observing systems that use models and data to improve air quality assessments for decision makers.

My role in the KORUS-AQ mission was CIMS operator at the Taehwa ground site. I set-up and operated the UC Irvine CIMS-OH Reactivity instrument and helped with the operation of a PTR-TOF-MS. I set up a high volume sampler to collect aerosol data and used packed sorbent cartridges (Tenax GR and Carbotrap 5TD) to sample BVOCs above and within the canopy.
