The estimation of the carbon budget in terrestrial ecosystems is one of the urgent research subjects regards climate change research and the implementation of Kyoto Protocol. Recently, the micrometeorological method has been widely used for evaluation of carbon exchange between terrestrial ecosystems and the atmosphere. However, the technique has not been standardised and diffused into developing countries yet, because it includes the variable factors in dependence upon aerial and land conditions. We propose the improvement of observations and the analysis methodology on flux measurements through a technical manual, information exchange at the workshop and the reanalysis of data.
