  1. BARCA CH4dataanalysis Flight 3 (17/06/2009) during BARCA Phase B in the wet season covering wetland area of Rio Negro and Rio Solimões BARCA Telecon 04-12-2009 MPI forBiogeochemistry Jena

  2. BARCA CH4dataanalysis Phase A: only CH4flaskmeasurementsareavailable; selectedflaskshavebeensentto Utrecht (Thomas Röckmann) for an isotope analysis Phase B : insituandflaskmeasurements – flasksarecurrentlybeinganalyzedandselectedflasksmight also besentto Utrecht thenfor an isotope analysis Comparisonof CH4datato global model output (TM5, TM3, etc.) Comparisonto regional model output (WRF-chem+VPRM-CH4, STILT) BARCA Telecon 04-12-2009 MPI forBiogeochemistry Jena

  3. Modeling plansfor BARCA Phase A and B Weather Research andForecast Model Transport of CO2, CH4and CO Stochastic Time InvertedLagrangian Transport Model Determination of CH4sourcesandsinks WRF-chem STILT ECMWF Data WRF met fields Running WRF with a newmodulegreenhousegases (chem_opt=98, includes VPRM, wetland-model,plumerise,etc.) for BARCA Phase A and Phase B for CH4, CO2and CO STILT runsfor CH4drivenbyeither WRF meteorologicalfieldsor ECMWF data BARCA Telecon 04-12-2009 MPI forBiogeochemistry Jena

  12. O2/N2 from BARCA flasks BARCA A: 145 flasks sucessfully anaylzed for O2/N2 ArN2 values used for correction of fractionation: O2/N2(corr) = O2/N2 – a(ArN2-mean(ArN2)) BARCA Telecon 04-12-2009 MPI forBiogeochemistry Jena

  13. O2/N2 from BARCA flasks - plans • Use STILT to separate contributions to O2/CO2 ratio from different processes • Respiration /Photosynthesis  VPRM fields von VY • Biomass burning (similar signature)  C. Wiedenmyer • Fossil fuel Julia’s COFFEE dataset for different fossil fuel types, 1x1 degree BARCA Telecon 04-12-2009 MPI forBiogeochemistry Jena
