  4. AGACC-II ScientificObjectives Advanced exploitation of Ground-based measurements for Atmospheric Chemistry and Climate applications– II AGACC-II willfurtherexperimental studies of the atmosphere usingground-basedremote-sensing(Brewer, FTIR, MAXDOAS, sunphotometer) and aerosol in in-situ instruments as well as supportinglaboratoryexperimentsandmodeling studies Improvementof the techniquesand retrieval algorithms  Expansion of the observationnetwork

  6. AGACC-II WP 1 objectives • Improved data on GreenhouseGases • FTIR measurements in the NIR of CO2, CH4, N2O at Ile de La Réunion in the frame of TCCON, Total Carbon Column Observing Network (connectedto ICOS) • Comparisonsbetween NIR and MIR data • Consistencywith in-situ surface data • Historical timeseries of CO2, CH4, N2O at the Jungfraujoch (1976 ) • Timeseries of CCl4and CF4 at Jungfraujoch  Timeseries and trends  Support tosatellite data retrievalsand carbon cyclemodeling

  7. Status of WP1 at mid-term • Analysis of historical timeseries of CH4 and N2O at Jungfraujoch • TCCON station at St Denis - Reunion in operationandofficiallyaccepted in the network; onset of timeseries andsubmission of data to database • CCl4 and CF4 retrievals, timeseries and trends analysis (Mahieu et al., JQSRT, 2012))

  8. AGACC-II WP 2 objectives • Developstrategiestodetect / improvequantification of additionalatmosphericconstituents at Ile de La Réunion andJungfraujochusing FTIR measurements : • Methyl chloride (CH3Cl) • Methanol (CH3OH) • Formaldehyde (CH2O) (+ MAXDOAS) • Ethylene (C2H4) • Ethane (C2H6) • Aceton ((CH3)2CO) • PAN (peroxyacetyl nitraat, C2H3NO5) • CClyandCFycomponents !!Needfordedicatedlaboratoryspectroscopic data Variabilityand timeseries • Support tosatellite data retrievalsandmodeling • Support to Montreal and Kyoto Protocol
