Vapour in the Climate System (WaVaCS)

Measurements of atmospheric water vapour

Various instruments on ground, balloon, aircraft, and satellite platforms are required for adequate observation of the extremely variable, spatio-temporal distribution of atmospheric water vapour. Accurate, height-resolved measurements of water vapour over the whole altitude range from the ground to the mesosphere are a challenging task for all available traditional and modern measurement techniques, as the water vapour mixing ratio varies over five orders of magnitude. The inter-comparison of various measurement techniques and methods allows the assessment of their accuracy and is a prerequisite for a planned and efficient improvement of instruments and data analysis techniques.

This is what WG1 of WAVACS is all about. More details can be found in the Memorandun of Understanding (MoU)
