  1. Retrieval of atmospheric CO2 from satellite near-infrarednadir spectra in the frame of ESA’s climate change initiativeM.Reuter , O.Schneising , M.Buchwitz , J.Heymann, H.Bovensmann, J.P.BurrowsInstitute of Environmental Physics, University of Bremen, Germany EGU, Vienna, Austria, 08.04.2011

  2. ESA’s GHG-CCI: Aims and Motivation

  3. ESA’s GHG-CCI: Road Map

  4. Two in-house algorithms

  5. BESD XCO2

  6. Park Falls, USA Bremen, Germany Darwin, Australia 350km 350km 350km Lauder, New Zealand 350km Validation with TCCON FTS measurements

  7. Comparison with FTS, CarbonTracker, GOSAT

  8. Statistics No statistical significant regional biases Single measurement precision ~2.5ppm Good agreement of year-to-year increase and seasonal amplitude

  9. WFMD XCO2

  10. Global increase

  11. CO2 uptake by growing vegetation Mean wind direction Fnet XCO2 gradiant approximately proportional to net surface flux Fnet XCO2 West East Longitude

  12. CO2 uptake by growing vegetation Overall very good agreement Canada: Stronger CO2 uptake ? Russia: Weaker CO2 uptake ?
