In this episode of the Barometer, Jen catches up with Professor Simon O'Doherty from the University of Bristol, to discuss the ground-based aspect of the GAUGE project.

Amongst other things, Simon and Jen discuss the importance of how measurement sites such as those from the UK Deriving Emissions linked to Climate Change (DECC) Network will help to quantify the UK emissions during the GAUGE project. Simon also talks about the Advanced Global Atmospheric Gases Experiment (AGAGE) network, specifically the Mace Head site in Ireland for which he is the principal scientist.
