Increasing levels of atmospheric carbon dioxide gas (CO2) from anthropogenic sources are of growing concern due to their impact on the global climate system. Research has shown that there is a strong link between increasing atmospheric CO2 concentrations and the warming climate. The global oceans are considered the only true net sink of atmospheric CO2. Understanding the exchange of CO2 between the ocean and the atmosphere is clearly of importance for monitoring the global carbon cycle and for climate modelling. However, there remain large uncertainties in the current parameterisations of air-sea gas interactions, which can have profound effects on the resulting global estimates of CO2 uptake. The OC-flux project was funded to exploit coincident Envisat data to investigate a number of these uncertainties.

Some of this work was undertaken during a visit (funded by a UK NCEO grant) to the ESA European Space Technology and Research Centre (ESTEC). All RA2 BRAT processing used the ESA Grid Processing On Demand (G-POD). Data post processing was achieved using resources provided by the UK NERC Earth observation Data Acquisition and Analysis Service (NEODAAS). This work was partly funded by the UK NERC marine research programme Oceans 2025.
