| dc.description.abstract | Using a helicopter-mounted portable spectroradiometer and continuous eddy covariance data we were able to evaluate the photochemical reflectance index (PRI) as an indicator of canopy photosynthetic light-use efficiency (LUE) in four boreal forest species during the Boreal Ecosystem Atmosphere experiment (BOREAS). PRI was calculated from narrow waveband reflectance data and correlated with LUE calculated from eddy covariance data. Significant linear correlations were found between PRI and LUE when the four species were grouped together and when divided into functional type: coniferous and deciduous. Data from the helicopter-mounted spectroradiometer were then averaged to represent data generated by the Airborne Visible Infrared Imaging Spectrometer (AVIRIS). We calculated PRI from these data and relationships with canopy LUE were investigated. The relationship between PRI and LUE was weakened for deciduous species but strengthened for the coniferous species. The robust nature of this relationship suggests that relative photosynthetic rates may be derived from remotely-sensed reflectance measurements. | |

Eddy correlation fluxes at the old jack pine site were collected by Dennis Baldocchi, Atmospheric Turbulence and Diffusion Division, NOAA, at the fen site by Shashi Verma, University of Nebraska and at the Old Aspen site fluxes were measured by a team consisting of researchers from the Atmospheric Environment Service, Downsview, Ontario and the University of British Columbia, the latter supported by a Collaborative Special Project Grant from the Natural Science and Engineering Research Council of Canada. The 1994 AVIRIS waveband data was provided by Robert Green, NASA Jet Propulsion Lab, California. | |
