Research Interests
My research interests are on boundary layer and micrometeorological
measurements, atmospheric turbulence and vegetation-atmosphere exchange
studies. Experiments involve turbulent flux measurements within and above vegetation
canopies using fast response sensors, wind profile measurements using
boundary-layer sodar and other routine measurements
of weather parameters. The results help understand different aspects of
vegetation-atmosphere interaction and also give insight into the representativeness of momentum, heat, water and carbon flux
measurements.
Our research also looks into the complexities of nocturnal boundary layer flow and turbulence and their influence on the flux measurements. Accurate measurements of nocturnal fluxes remain a challenging task due to the presence of weak and intermittent turbulence, low-level wind jets, different types of wave motions and local circulations. Depending on terrain characteristics and ambient atmospheric conditions, either some or all of the above factors may influence the measurements. One important aspect of our ongoing study specifically looks into the detailed characteristics of low-level jets, their role in enhancing turbulent mixing in the canopy layer and on the influence on carbon flux measurements.
