Abstract:
Forest Ecosystem Dynamics Multisensor Airborne Campaign (FED MAC): Bidirectional Reflectance Measurements of Forest Canopy Using PARABOLA The Biospheric Sciences Branch (formerly Earth Resources Branch) within the Laboratory for Terrestrial Physics at NASA's Goddard Space Flight Center and associated University investigators are involved in a research program entitled Forest Ecosystem Dynamics (FED) which is fundamentally concerned with vegetation change of forest ecosystems at local to regional spatial scales (100 to 10,000 meters) and temporal scales ranging from monthly to decadal periods (10 to 100 years). The nature and extent of the impacts of these changes, as well as the feedbacks to global climate, may be addressed through modeling the interactions of the vegetation, soil, and energy components of the boreal ecosystem. The Portable Apparatus for Rapid Acquisition of Bidirectional Observations of Land and Atmosphere, or PARABOLA instrument (see Deering and Leone, 1986 for a complete description) was employed to measure the directional radiances in essentially the complete 4 pi irradiance field above and below the spruce-hemlock canopy under cloudless and overcast sky. The PARABOLA is a three-channel (visible, near infrared, and mid-infrared; 0.650-0.670, 0.810-0.840, and 1.620-1.690 um, respectively), radiometer with a scanning head that turns on two axes, which enables the acquisition of radiance data for almost the complete sky- and ground-looking hemispheres in 15 degrees instantaneous field-of-view sectors in only 11 s. Measurements were made during the 1989 experiment with the instrument deployed on the meteorological tower using a 6.5 m triangular truss boom. To avoid tower shadowing in 1991, a specially contructed 32 m telescopic mast was supported on a 4 m long by 1.8 m wide, hollow-frame trailer adapted for mounting the PARABOLA.
