| Abstract: | Surface features such as soil moisture and vegetation have a profound impact on the surface energy balance and the atmospheric
boundary layer. To quantify this effect for a tropical location, a detailed field experiment, VEBEX, was designed and successfully
executed in a tropical site at Bangalore, India. VEBEX was a joint experiment between the North Carolina State University,
Indian Institute of Science (IISc), and the University of Agricultural Science (UAS) at Bangalore, India. Continuous surface
meteorological measurements were taken over an entire crop period (pre-sowing to post-harvest). During different stages of
the plant growth, intensive observations of surface turbulence, and measurements of physiological and soil moisture measurements
were also conducted. The results obtained provide an insight into the unusually strong variability for the tropics. Interpretation
of the observations and an overview of the analysis procedure and future research initiatives are also presented. |
