Project Abstract

We propose the use new modular Bayesian inversion framework, called FLEXINVERT, for estimating the surface fluxes of atmospheric trace species including methane. These estimates will incorporate in-situ measurements from Ireland�s Green House Gas (GHG) observational network (ICOS �IRELAND) as well as data from UK monitoring networks. The inversion methodology will be piloted for other routinely monitored species at sites across Ireland and the UK including N20. The model will be intercompared with GEOS-Chem for selected periods and the use of satellite data (We will use level-2 column CO2 and CH4 measurements from the Japanese Greenhouse gases Observing SATellite (GOSAT) retrieved by the University of Leicester, which represent column values along the orbital tracks) for the inclusion into FLEXINVERT will be explored. These intercomparisons of inversion methodology using the same sites help further our understanding of uncertainties in these estimates. Testing of a new algorithm for CO2 inversion being developed at NILU (Norweigan Institute for Air Research) will also be undertaken. These top down estimates will help to further our understanding of emissions and reconcile the bottom up and top down approach.
