The Flux Observations of Carbon from an Airborne Laboratory (FOCAL) project is a cooperative effort among the Anderson Group from Harvard University, Aurora Flight Sciences, and NOAA's Atmospheric Turbulence and Diffusion Division (NOAA/ATDD) to add scientific instruments to a Diamond Aircraft DA-42 Twin Star aircraft to measure fluxes of CO2 and CH4 in the planetary boundary layer. The work, funded by the National Science Foundation in 2012, uses the Anderson Group's Integrated Cavity-Output Spectroscopy (ICOS) instrument suite to measure concentrations and isotopologues of CO2 and CH4, NOAA/ATDD's Best Airborne Turbulence (BAT) probe to measure atmospheric turbulence in 3-dimensions, and Aurora Flight Sciences' DA-42 Twin Star aircraft to carry the complete instrument package. The DA- 42 collected 36.9 hours of research data based from Deadhorse Airport in Prudhoe Bay, Alaska in August, 2013. A flight track was created to compare the CO2 and CH4 flux measurements made by instruments aboard the DA-42 against a groundbased tower which made simultaneous CO2 and CH4 flux measurements. Flight tracks were then expanded to measure fluxes far beyond the tower comparison area. Tracks were flown over inland melt-pond lakes and the Arctic Ocean to monitor CH4 concentrations and fluxes, as well as to compare coincident measurements of bulk water-column and in-situ tundra flux measurements made by the Naval Research Laboratory (NRL). Tracks were also flown to characterize the background CO2 and CH4 concentrations around the Prudhoe Bay oil fields. This report describes the NOAA/ATDD BAT probe instrumentation and the August 2013 Alaska flight campaign. [doi:10.7289/V5/TM-OAR-ARL-267 (http://dx.doi.org/10.7289/V5/TM-OAR-ARL-267)]
