THE ENERGY BUDGET AT THE EARTH'S SURFACE: ORIGINS OF SHORT-TIME CO2 FLUCTUATIONS IN A CORNFIELD

Abstract

Studies of the vertical distributions of CO2 fluctuation in a cornfield were made in the 4 to 0.25 cycle/minute frequency range. Amplitude of fluctuations decreased with height above the ground. Frequency in this range appeared rather constant, however. Sources and sinks for CO2 within the cornfield contribute in part to the fluctuations. However, eddy structure originating inside and/or outside the cornfield plays an important role too.
