Non-CO2 reductions will be needed (too)!
n 2 ºC limit in 2100 hard to reach n CO2 –eq=2 ºC -> 450 ppm
n a = 2010 (non-)CO2 emissions n b = 80% reduct. non-CO2 n c = 80% reduct. CO2
n d = 80% reduct. CO2+non-CO2
Montzka et al, Nature, 2011 N2O is currently biggest ODS
(Ravishankara et al, 2009) Emission reductions >80%: verification!

Links with air quality/ atm. composition change research
n Almost same anthropogenic sources, same atmosphere! n GHG’s are ~passive tracers: ultimate test
n Can be measured very precise, less uncertainties (deposition, reactions, sampling artefacts)
n Test for minimising transport errors in atmospheric transport models n Very sensitive to vertical mixing processes
n Ideal case for setup of multi tracer constrained inversions n Improvement of GHG emissions by verification-> improvement of
other emissions as well (time and place)! n Baseline monitoring infrastructure should be shared, almost same
demands

InGOS now and in the future
n InGOS now well underway (~24 months) showing good progress
n InGOS integrates different communities (surface measurements, remote sensing and modelling)
n InGOS will provide n Harmonized historic datasets for continuous European obs. of
CH4, N2O, SF6, H2, inclusive error analysis n Near realtime continuous data for CH4, N2O, SF6, H2, 222Rn… n Improved regional emission estimates (bottom up+top down) n Network design for non-CO2 monitoring n Improved measurement techniques and methods

3rd ACCENT+ Symposium, Urbino, Italy: 17-20 September, 2013
InGOS beyond 2015
n Further expand, improve consistency and quality of network n Test and deploy new (optical) techniques n Increase links and synergy:
n ICOS n ACTRIS n AQ networks n Urban networks: mobile platforms n Link to FP7 + Horizon 2020 projects
n Extend use of observations to full temporal resolution n Additional isotopic ratio obs.: better source characterisation n Deploy new remote sensing platforms, expand TCCON ground
truthing (e.g. Tropomi) at co-located sites
