The overall objectives of PARIS are:

1) Quantify top-down emissions from a selection of European countries of all the major GHGs reported under the UNFCCC (CO2, CH4, N2O and F-gases), and black carbon aerosol (BC) reported under CLRTAP.

2) Quantify the contribution of major source sectors of GHG and BC emissions and organic matter aerosol (OM) abundance through the implementation of innovative measurement and analysis technologies.

3) Derive time- and space-resolved flux estimates for GHGs with complex or uncertain source distributions (N2O, F-gases)

4) Produce draft Annexes to the annual National Inventory Reports (NIRs) for a selection of ‘focus’ countries
