BARCA CH4 data analysis
Phase A: only CH4 flask measurements are available; selected flasks have been
sent to Utrecht (Thomas Rckmann) for an isotope analysis
Phase B : insitu and flask measurements flasks are currently being analyzed and
selected flasks might also be sent to Utrecht then for an isotope analysis
Comparison of CH4
data to global model output (TM5, TM3, etc.)
Comparison to regional model output (WRF-chem+VPRM-CH4, STILT)

Running WRF with a new module greenhouse gases (chem_opt=98,
includes VPRM, wetland-model,plumerise,etc.)
for BARCA Phase A and Phase B for CH4, CO2 and CO
STILT runs for CH4 driven by either WRF meteorological fields or

WRF Validation
Participation in evaluation and testing of the WRF set-up for the Amazon region
(mostly done at INPE)
1. Precipitation/Convection
Evaluation of WRF precipitation output against TRMM and GPCP data
2. Radiation
Aeronet data available for 2002 (six stations) and 2008/2009 (only Alta
Floresta and Rio Branco)
Validation of WRF Amazon setup (lw 1 & sw 2 options) against Aeronet data
for BARCA Phase A and Phase B
also interesting for use of VPRM

WRF runs
Tagged tracer WRF runs for BARCA Phase A and Phase B for CH4, CO2 and CO
to scale different sources in comparison with the observatios
Subroutines for VPRM, wetland model (Kaplan wetland inventory) and termites
are combined under the new module_greenhouse_gases (chem_opt=98) which
also uses the plumrise mechanism VPRM parameters & preprocessing
Until global fields of CH4, CO2 and CO are available for 2008 and 2009, 5x5fields interpolated from NOAA surface stations are used for initial and boundary
conditions
Could somebody already provide the NOAA surface station data for May 2009?
The WRF biomass burning preprocessor wrf_chem_prep_source was installed in
Jena and biomass burning emissions estimates (including the Modis satellitedata) can now be provided on WRF and Lat/Lon grid also in netcdf output
We would still need the satellite data for May 2009 (WF_ABBA & DSA)
EDGAR 4 data are used for anthropogenic sources CO data?
Importance of vegetation CH4 source and soil uptake CH4 still has to be discussed

STILT runs for BARCA
STILT to provide consistent footprint information-> Source region identification
Fast forward tagged tracer runs for receptors along flight path
-> hypothesis testing for different fluxes
Inverse analysis (nested inversion)
-> optimal source configuration

STILT runs for BARCA Status
Domain set up (-35 -85 Lat Lon south-west, 15 -30 Lat Lon north-east)should be identical to VY domain!
STILT-ECMWF: ECMWF preprocessing for Phase A and B running
STILT-WRF: waiting for WRF fields
Coupling to fluxes:
Biomass burning fields (C. Wiedenmyer (UCAR)) available as ncdf
EDGAR V4 and others used in WRF-chem need preprocessing to
cartesian grid
VPRM parameters and fields -> VY domain?

O2/N2 from BARCA flasks
BARCA A: 145 flasks sucessfully anaylzed for O2/N2ArN2 values used for correction of fractionation: O2/N2(corr) = O2/N2a(ArN2-mean(ArN2))
