The UK DECC (Deriving Emissions linked to Climate Change) Network consists of five sites in the UK and Ireland measuring greenhouse and ozone-depleting gases. The four UK-based sites (Ridge Hill, Herefordshire; Tacolneston, Norfolk; Bilsdale, North Yorkshire; and Heathfield, East Sussex) sample air from elevated inlets on tall telecommunications towers. Mace Head, situated on the west coast of Ireland, samples from an inlet 10 meters above ground level and is ideally situated to intercept baseline air from the North Atlantic Ocean. This collection contains high frequency measurements of all major greenhouse gases made at the four UK stations, including carbon dioxide, methane, nitrous oxide and sulfur hexafluoride. Mace Head data are available separately - see link in documentation. Data from the UK DECC network are used to assess atmospheric trends and quantify UK emissions, and feeds into other international research programs, including the Integrated Carbon Observation System (ICOS) and Advanced Global Atmospheric Gases Experiment (AGAGE) networks.
This work is funded by the UK Department for Business Energy and Industrial Strategy (BEIS) under contract 1537/06/2018 to the University of Bristol and through the National Measurement System at the National Physical Laboratory.
