I am working on the HOx/RO2 instrument for the NCAR-NSF GV (HIAPER) through the Upper Troposphere-Lower Stratosphere (UTLS) TIIMES initiative for the upcoming Deep Convective Clouds & Chemistry Experiment (DC3) Field experiment for the last year. During this time, work on the instrument design has been discussed, and a number of pumps and other components have been selected and ordered, and I participated in ARCTAS, which our group used as a testbed for high altitude HOx observations.
We deployed our previous instrumentation in the Megacities Impact on Regional & Global Environment (MIRAGE), the Intercontinental Chemical Transport Experiment (INTEX-B) campaigns and the Pacific Atmospheric Sulfur Experiment (PASE) field sudies and are now analyzing the data. The current system was deployed on the NASA DC-8 during Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS), and many components of this system will serve as components of our final HOx HIAPER instruments.
The Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS) field campaign is poised to help scientists identify how air pollution contributes to climate changes in the Arctic. During the spring deployment, which took place in April in Fairbanks, Alaska, scientists gathered information about the effects of Arctic haze, stratosphere-troposphere exchange, and sunrise photochemistry (chemical reactions that occur when sunlight returns to the Arctic in spring). During the summer deployments in July & July in Palmdale, California, and in Cold Lake, Alberta, the team investigatee how emissions from northern wildfires affect the Arctic’s atmosphere.
