Abstract: Tall vegetation and complex terrain create difficult conditions for measuring and modeling net ecosystem?atmosphere exchanges of carbon, water vapor, and pollutants. The instability of canopy flow regimes over complex ...

Abstract: To understand the basic characteristics of the observed S-shaped wind profile and the exponential flux profile within forest canopies, three hypotheses are postulated. The relationship between these fundamental profiles ...

Abstract: Time series of mixed layer depth, zi, and stable boundary layer height from March through October of 1998 are derived from a 915-MHz boundary layer profiling radar and CO2 mixing ratio measured from a 447-m tower in northern ...

Abstract: Methodology for determining fluxes of CO2 and H2O vapor with the eddy-covariance method using data from instruments on a 447-m tower in the forest of northern Wisconsin is addressed. The primary goal of this study is the ...
