Abstract

This version 26.01 dataset collection consists of atmospheric trace gas observations made as part of the UK Deriving Emissions linked to Climate Change (DECC) Network. It includes core DECC Network measurements, funded by the UK Government Department for Energy Security and Net Zero (TRN1028/06/2015, TRN1537/06/2018, TRN5488/11/2021 and prj_1604) and through the National Measurement System at the National Physical Laboratory, supplemented by observations funded through other associated projects. The core DECC network consists of five sites in the UK and I
reland 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 within 10 metres of ground level and is ideally situated to intercept baseline air from the North Atlantic Ocean. Data from the decommissioned DECC network site at Angus Tall Tower are also included in this dataset collection, as are data from the affiliated (non-core) sites at Invergowrie (Perth and Kinross), Jodrell Bank (Cheshire), Lerwick (Shetland), and Valentia Island (County Kerry, Ireland). The measurement site at Weybourne, Norfolk, funded by the National Centre for Atmospheric Science (NCAS) and operated by the University of East Anglia, is also affiliated with the network. Weybourne data are archived separately - see links in documentation. Data from the UK DECC network are used to assess atmospheric trends and quantify UK emissions, and feed into other international research programs, including the Integrated Carbon Observation System (ICOS) and Advanced Global Atmospheric Gases Experiment (AGAGE) networks.

Data lineage:

Data were collected using in situ trace gas analysers. Data quality assurance and quality control is carried out regularly by each station PI, and overall DECC Network data reviews are conducted every 2 months. Data are traceable to international calibration scales. Data were collected by the DECC network team and deposited at the Centre for Environmental Data Analysis (CEDA) for archiving.

Data Quality:
Data are as given by the data provider, no quality control has been performed by the Centre for Environmental Data An alysis (CEDA)
