Abstract:
This project has the dual goals of refining the constraints on northern hemispheric gross primary production based on time series of the oxygen isotopes of CO2 and of conducting a synthesis of seasonal cycles in atmospheric CO2 and satellite-based productivity, to look for trends in norther extra-tropical carbon cycling over the past few decades.
