  6. Communications in 2013 • At NDACC Working Group meetings and International DOAS Workshop ( Abashiri, June 10 – 14, 2013; Boulder, USA, 12-14 August 2013 • At TCCON annualmeetings (Abashiri, June 10 – 14, 2013) • At European Aerosol Conference (Prague, 1-6 September 2013.) • At EGU (Vienna, 07-12 April 2013). • At AGU (San Francisco, 09-13 December 2013) • At ESA and EUMETSAT meetings ACVE, Frascati, 13-15 March 2013; Living Planet Symposium, Edinburgh, 9-13 September 2013; Meteorological Satellite Conference, Vienna, 16-20 September 2013 • SI2N meeting, 18-19 September, Helsinki, Finland, 2013. • At Symposia on High Resolution Molecular Spectroscopy (Ohio, USA, 17-21 June 2013; Budapest, Hungary, 25-30 August 2013).

  7. Data dissemination & submission to international databases • Reunion Island TCCON data (http://tccon.ipac.caltech.edu/) • Reunion Island NDACC data (ftp://ftp.cpc.ncep.noaa.gov/ndacc/station/reunion/hdf/ftir) • Jungfraujoch NDACC data (ftp://ftp.cpc.ncep.noaa.gov/ndacc/station/jungfrau/hdf/ftir) (ftp://ftp.cpc.ncep.noaa.gov/ndacc/RD/jungfrau/hdf/uvvis/) • ULB spectroscopic data will be proposed for inclusion in HITRAN

  8. Perspectives WP1 • Continuation of TCCON and NDACC observations at both stations at Ile de La Réunion, with focus on NDACC at Maido and TCCON at St Denis • Extension of timeseries at Jungfraujoch • Further work on understanding of discrepancy between CH4 from MIR and NIR spectra and on comparisons of CO between NIR and MIR • Geophysical analyses of first TCCON timeseries • Contributions to WMO 2014 Scientific Assessment of Ozone Depletion

  9. Perspectives WP2 • Furtherwork on PAN, acetoneand CH3Cl retrievals at La Réunion – in particular at Maido • and on PAN, acetone, CH3Cl retrievals at Jungfraujoch • Re-analysis / improvement of C2H4, C2H6 and H2CO data at Jungfraujoch and La Réunion with improved spectroscopic data and common retrieval strategies where feasible • Finalisation of HCFC-142b time series Final time series of CFC-11, CFC-12 and HCFC-22 have been produced from 2000 onwards. They will be combined with the HCFC-142b and either with the CCl4 or CF4 weighted contributions to generate ‘final’ CClyand CFy total column budgets. • Updated H2CO comparisons at Jungfraujoch between MAXDOAS and FTIR observations

  10. Perspectives WP2 – laboratory spec’y • H2CO: • finalize the analysis of the FIR and IR spectra, after correction of intensity offset. • Compare to HITRAN2012 • Assess quality of the modeling of the whole 1and  5band system (2500–3200 cm–1) using the improved linelistusing atmospheric spectra • C2H4: • Publication of results including the new HITRAN 2012 linelist • Assessment with atmospheric spectra • 2nd paper with results from frequency analysis • C2H6: • finalize the linelist for the  7and 8+ 11bands of ethane • assess quality with laboratory and atmospheric spectra

  11. Perspectives WP 3 • Calibration campaign of both Brewers in Ukkel • Expansion of ceilometer network, and submission of data to European network users. (E-profile, EUMETNET) • Data from the LIDAR-ceilometer at Uccle will be used to test calibration algorithms for a working group of TOPROF (COST). • Implement changes to OPAC in order to get more accurate results for the modeled AOD and SSA values. • Further investigation of correlations between the source regions of the aerosols and the observed AOD and SSA and their relation with meteorological conditions. • Installation of nephelometer

  12. Perspectives WP3 – cont’d • Publication with the results of the linear trend analysis, change point analysis and multiple linear trend analysis of erythemal UV dose, global solar radiation, total ozone and AOD at 320nm from Brewer data. • Analysis of all aerosol data in Uccle. Further study the observed aerosol characteristics, and their influence on and by meteorological conditions such as clouds and/or the boundary layer height. Study of diurnal cycle, looking for links with meteorological and/or traffic conditions. • study of radiative forcing by aerosols, based on data base of measurements available in Uccle and radiative transport modelling

  13. Perspectives WP 4 • Analysis of CIMEL and MAXDOAS data in Bujumbura • Exploitation of MAXDOAS measurements in Bujumbura, including interpretation using ancillary data (from 3D chemistry transport models and satellite measurements) • Investigation of transport of emissions and their impact on measurements in Bujumbura and Reunion Island (using FLEXPART dispersion modeling)

  14. Conclusions AGACC-II (Jan. 2011- end 2014) progresses as planned: The most important problem has been the delay of the installation of the MAXDOAS and CIMEL instruments in Burundi due to manpower problems. We foresee to achieve the objectives almost completely.
