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)

WRF Validation

  • Participation in evaluationandtestingofthe WRF set-upforthe Amazon region (mostlydoneat INPE)

  • Precipitation/Convection

  • Evaluation of WRF precipitationoutputagainst TRMM and GPCP data

  • Radiation

  • Aeronetdataavailablefor 2002 (sixstations) and 2008/2009 (only Alta Florestaand Rio Branco)

  • Validation of WRF Amazon setup (lw 1 & sw 2 options) againstAeronetdatafor BARCA Phase A and Phase B

  •  also interestingforuseof VPRM

WRF runs

Taggedtracer WRF runsfor BARCA Phase A and Phase B for CH4, CO2and CO toscale different sources in comparisonwiththeobservatios

Subroutinesfor VPRM, wetland model (Kaplan wetlandinventory) andtermitesarecombinedunderthenewmodule_greenhouse_gases (chem_opt=98) which also usestheplumrisemechanism VPRM parameters & preprocessing

Until global fieldsof CH4, CO2and CO areavailablefor 2008 and 2009, 5°x5° fieldsinterpolatedfrom NOAA surfacestationsareusedforinitialandboundaryconditions

Couldsomebodyalreadyprovidethe NOAA surfacestationdatafor May 2009?

The WRF biomassburningpreprocessorwrf_chem_prep_source was installed in Jena andbiomassburningemissionsestimates (includingtheModissatellitedata) cannowbeprovided on WRF andLat/Lon grid also in netcdfoutput

Wewould still needthesatellitedatafor May 2009 (WF_ABBA & DSA)

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))

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
