September 1, 1997 to August 30, 2000
Project Description: 


  1. Observe and simulate how surface processes and boundary-layer development interact to modulate NEE of CO2.
  2. Derive tropospheric CO2 mixing ratios via estimates of the entertainment flux and compare the modeled values.
  3. See if the the results vary across North America and/or ecosystems.
