Amendment 4: Delay of Due Date for A.23 FIREChem

Amendment 4 delays the due date and airborne campaign for Program Element A.23 Fire Impacts on Regional Emissions and Chemistry (FIREChem).

Program Element A.23 seeks proposals for participation in an airborne campaign to be conducted in the continental U.S. during July, August, and into mid- September of 2019 to improve our understanding of the transport of and chemical transformations in biomass burning plumes and their impact on air quality. A single comprehensively instrumented research aircraft is required to accomplish this research. In this airborne campaign, the NASA DC-8 may provide observations from near surface up to ~12 km. Aircraft measurements of atmospheric trace gas mixing ratios and aerosol particle properties and meteorological parameters provide a comprehensive suite of observations to understand these processes during the focused experiment period. They are also useful for calibration and validation of the longer-term observations of Earth observing satellite sensors and the retrieved data products generated from those observations.

One of the aircraft associated with the NASA FIREChem campaign needs to be re-winged in the summer of 2018, so the FIREChem campaign is now planned for July – September, 2019. Under the revised schedule, PIs will have a year to prepare for the field campaign, participate in the mission in year 2, and have the third year for data analysis.

Proposals are now due June 16, 2017. Notices of intent are not requested for this program.
