Measurement Techniques for GHG Emission from ...

Intermediately the methods have been developed to measure gross green house gas fluxes from reservoirs and natural water bodies and as a result, thin boundary layer and floating chamber method are developed. The former makes use of floating chambers with in situ or ex situ laboratory analysis and the latter use of floating chambers coupled to an automated instrument (NDIR or FTIR). Over the years many tests were done to compare the methods. There is no significant difference in the results obtained with the
