University of Bristol (UNIVBRIS), WP 6 lead, will contribute to dual methane isotopologue measurements, F-gas measurements from Cabauw flasks, and the inverse modelling for CH4, N2O, CO2, and F-gases in WP 3,4,5,6. UNIVBRIS houses a state-of-the-art atmospheric laboratory measuring greenhouse gases and ozone depleting substances and is a leading member of the Advanced Global Atmospheric Gases Experiment (AGAGE) contributing measurements of non-carbon dioxide gases to the global greenhouse gas community. UNIVBRIS runs the United Kingdom’s national greenhouse gas monitoring network, DECC (Deriving Emissions linked to Climate Change) funded by the UK government and will provide access to DECC sites for installation of methane isotopologue and APO measurements. UNIVBRIS has access to multiple high-performance computing (HPC) servers for simulation of NAME footprints and for the inverse modelling analyses in PARIS.

Met Office (MO), WP 2 lead, will oversee the synthesis of all top-down results generated in PARIS for engagement with national inventory teams. MO will also provide inverse modelling outputs for F-gases (in WP 3), CH4 (in WP 4) and N2O (in WP5). MO currently conducts the top-down modelling for the UK DECC project and for the past 20 years, has annually written the Annex to the UK NIR. The MO will provide the computer resource and infrastructure to generate the required NAME footprint simulations required for this project. The MO also provide the global and high-resolution 3-D meteorological fields required for the NAME simulations.

University of Edinburgh (UEDIN) will work with UNIVBRIS in WP 4 to construct a second dual methane isotopologue instrument for in situ deployment at either SOAR or LUT. UEDIN will also extend methane δD and δ13C observations at HFD for the duration of the project. UEDIN collaborates very closely with the National Physical Laboratory (UK’s National Metrology Institute) in equipping and running the HFD observatory and specifically in observatory for atmospheric research, which will allow space for deployment of instrumentation under PARIS.

University of East Anglia (UEA) will contribute to WP 6 of the project, delivering high-precision, high-frequency atmospheric APO and CO2 data from UK stations, and using APO to separate fossil fuel and terrestrial biospheric variations in CO2 at each site. UEA’s access to critical infrastructure includes: a) the Carbon Related Atmospheric Measurement (CRAM) Laboratory in the School of Environmental Sciences, which is the UK’s only laboratory with high-precision atmospheric O2 instrumentation and measurement expertise; b) the Cylinder Filling Facility (CFF), a purpose-built facility for the preparation of reference and calibration cylinders required to make high-precision atmospheric O2 and greenhouse gas measurements; c) the Weybourne Atmospheric Observatory, operated by UEA, which is home to Europe’s longest-running continuous atmospheric O2 and CO2 records (12 years), and is also an NCAS (UK National Centre for Atmospheric Science) Atmospheric Measurement and Observation Facility, WMOGAW (World Meteorological Organization, Global Atmosphere Watch) Regional station, and a European ICOS (Integrated Carbon Observing System) station.
