Park Falls, USA Bremen, Germany Darwin, Australia 350km 350km 350km Lauder, New Zealand 350km Validation with TCCON FTS measurements
Statistics No statistical significant regional biases Single measurement precision ~2.5ppm Good agreement of year-to-year increase and seasonal amplitude
CO2 uptake by growing vegetation Mean wind direction Fnet XCO2 gradiant approximately proportional to net surface flux Fnet XCO2 West East Longitude
CO2 uptake by growing vegetation Overall very good agreement Canada: Stronger CO2 uptake ? Russia: Weaker CO2 uptake ?
