3rd GAW Expert Workshop on VOCs

The 3rd GAW Expert Workshop on Volatile Organic Compounds will be organized on 29-30th June 2010

Helsinki, Finland.

The workshop is organized in support the Reactive Gases component of the Global Atmosphere Watch (GAW) programme. This will be the third workshop in a series which has already defined a programme of VOC measurements to be made in a global network recently announced in an article in EOS. 

Short summary of the meeting can be found here.
