Recent micrometeorological studies of sensible heat flux in the plant-atmosphere system

For many years scientists working in fields related to micrometeorology have used the “Eddy Covariance (EC)” technique to study the transfer of water vapour, carbon dioxide and other greenhouse gases between plants, soils, bodies of water and the atmosphere at the boundary layer. This complex statis...
