Multisensor Aircraft Campaigns (FED/MAC)

Selected data from NASA`s Forest Ecosystem Dynamics (FED) project have been assimilated and is available for use by the general scientific community. These data represent measurements taken during the Multisensor Aircraft Campaigns (FED MACs) between the years 1989 and 1991 as part of the field component of the FED project and are available here or on a 3.5" PC compatible floppy disk (Walthall et. al., 1993).

• Data
  
• Measurement of atmospheric attenuation and hence estimate of the aerosol optical thickness.
  
• Airborne Laser Polarization Experiment (ALPS).
  
• Basic Meteorological Data.
  
• Dielectric and Pressure Bomb Data for hemlock and red spruce.
  
• Helicopter mounted SE-590 Spectrometer.
  
• Helicopter mounted Modular Multiband Radiometer (MMR).
  
• Measurement of hemispherical downwelling solar irradiance and hemispherical upwellingreflected radiance from the forest canopy.
  
• Hemlock Tree Tertiary Branch Measurement.
  
• Leaf Area Indices.
  
• Needle absorptance characteristics of red spruce (Picea rubens), eastern hemlock (Tsuga canadensis), cedar, balsam fir, and white pine (derived from needle reflectance and transmittance measurements).
  
• Portable Apparatus for Rapid Acquisition of Bidirectional Observations of the Land and Atmosphere (PARABOLA). Contact Don Deering, email Donald.W.Deering@nasa.gov.
  
• Soil Moisture and Soil and Air Temperatures.
  
• Stem Map of spruce site.
  
• The SWOE Thermal Analysis and Measurements Program (STAMP). Measurements of the temperature distribution within a bigtooth aspen were obtained to support development of a 3-D thermal model of trees.
  
• The Visible / Infrared Intelligent Spectrometer (VIRIS) and a portable illumination source (a spectralon coated hemisphere/baffle system employing 4, high-intensity, quartz line, 30 W bulbs) were used to characterize the reflectance of branch samples with needles attached (spruce and hemlock).
