GAUGE - Greenhouse gAs Uk and Global Emissions 

The FAAM research aircraft will provide a broad-scale 3-D perspective on the UK inflow and outflow GHG budgets, complementing information from the existing tall tower (DECC) network, high frequency measurements aboard a North Sea ferry, and also linking with existing (GOSAT) and planned (OCO-2) satellite measurements.

 

Objectives:

  1. A 42-month research programme to:
  2. develop high-resolution estimates of UK greenhouse gas (GHG = CO2, CH4, N2O) budgets, through:
  3. inversion modelling on both a regional (UK and finer) and global scale, to assist in:
  4. the design of a national environmental policy directed at GHG inventory verification and climate change.

The GAUGE measurement strategy is directed at providing data that enables models to link flux estimates from fine scales (<10 km) through regional (10s km e.g., devolved administrations) and sub-continental (100s km, e.g. UK) scales to continental scales (1000 km).

The FAAM research aircraft will provide a broad-scale 3-D perspective on the UK inflow and outflow GHG budgets, complementing information from the existing tall tower (DECC) network, high frequency measurements aboard a North Sea ferry, and also linking with existing (GOSAT) and planned (OCO-2) satellite measurements.

Tailored regional case studies of GHG emissions from over East Anglia and the Welsh borders will improve our understanding of, and quantify emissions from, different source sectors. Building on NERC investment in ClearFlo, we propose a measurement intensive to quantify GHG fluxes from London, which will use the FAAM aircraft to sample profiles of upwind/downwind air, validate dedicated satellite observations, and link urban measurements with downwind in situ and tall tower measurements.

GAUGE will also seek to test/validate and characterise both novel and existing methods for flux estimation either directly or as assimilated in models, e.g. satellites (GOSAT and OCO-2) and remote sensing techniques (LIDAR, FTIR etc).
To synthesize the GAUGE dataset to produce GHG flux estimates across the UK, Europe, and the globe we will employ world-leading regional and global atmospheric transport and inverse models.

GAUGE will engage with stakeholders to provide knowledge exchange. Institutions and agencies such as ECMWF (MACC product), Defra (agricultural emissions) and DECC (GHG inventory) will be consulted to discuss the new findings from this project and the policy impacts they will have.

TOTAL Drag Index     324

Maximum Drag Index Value = 245, unless both the HOx FAGE Inlet and the CIMS (ROx) inlet are removed, in which case the Maximum Drag Index Value =257.

 

The value of 324 is a theoretical maximum since this covers three separate campaigns. The range for the three campaigns is still high however, in the range of 260 - 300.
