Aircraft flux measurements during FIFE and BOREAS

Desjardins, R.L., MacPherson, I., Schuepp, P.H., Worth, D.E., Pattey, E. 2016. Aircraft flux measurements during FIFE and BOREAS. How FIFE and BOREAS changed the world Goddard Space Flight Center Greenbelt 2016/10/06 - 2016/10/07.


Aircraft flights conducted during FIFE and BOREAS contributed substantially to our understanding of flux measurements, and flux measuring systems. These flights allowed for the testing of strengths and weaknesses of different measurement approaches to be used with the eddy covariance method and were critical in the development of the footprint concept for relating fluxes of mass and energy to a source area. Long-transect flights conducted during FIFE and BOREAS have also proved to be useful in explaining the importance of mesoscale transfer on the lack of energy budget closure typically observed by eddy covariance. Further, these experiments have provided a database of integrated observations which are essential for understanding and modeling land-atmosphere interactions, as well as for the development of environmental response functions. This database will continue to sustain high-value research for many years to come. Based on results obtained during FIFE and BOREAS, it is recommended that for future aircraft-based studies as a part of large-scale projects, fewer tower/aircraft inter-comparisons be conducted, and instead that there be more of a focus on budget studies, and that that taking repeated measurements over long transects represents the best way to capture spatial and temporal variability, as well as to incorporate all frequency scales.
