Partitioning of ocean and land uptake of COz as inferred by measurements from the NOAA Climate Monitoring and Diagnostics Laboratory Global Air Sampling Network
Abstract. Using •13C measurements in atmospheric CO 2 from a cooperative global air sampling network, we determined the partitioning of the net uptake of CO2 between ocean and land as a function of latitude and time. The majority of •13C measurements were made at the Institute of Arctic and Alpine R...
