24 international students just completed our 1-week summer school on greenhouse gases in the atmosphere, the oceans and the terrestrial biosphere (16-23 Aug. 2015, Edinburgh).

Gaining practical experience in different measurement techniques was a main focus of the school. For two days we visited Harwood Forest, Northumberland, a site of this year's intensive field campaign of the GREENHOUSE project. Students learned to estimate carbon stocks and biomass, and got introduced to GHG flux measurements with eddy covariance techniques and flux chambers. Back in Edinburgh, the students took water samples at harbours along the Firth of Forth, and on short trips with the new School of GeoScience boat, to investigate the variation of dissolved inorganic carbon (DIC), and had a chance to try flying an unmanned aerial vehicle (UAV) for atmospheric GHG profiles.

These practical outdoor exercises were complemented by computing exercises analysing airborne measurements and ocean model data, as well as lectures on the role of CO2, CH4 and N2O in a global context and the use of remote sensing.

Colleagues from Forest Research, the National Oceanography Centre (NOC), and the universities of Edinburgh, York, Exeter, Manchester, Leicester, and East Anglia, and University College London (UCL) contributed to the teaching. The school was organised and funded as part of the Greenhouse Gases Emissions and Feedback Programme. The EU ClimMani COST action also supported travel and accommodation for international students with a total amount of 11950€.
