The validation of observations from remote sensors is an important objective of airborne field campaigns conducted under NASA’s Tropospheric Chemistry Program. Through the quantitative comparison of retrievals and in-situ measurements from aircraft, the validation of remotely-sensed observations is feasible. This approach was first successfully demonstrated by the under-flight of EOS Terra by the NASA DC-8 during the 2001 TRACE-P mission for validation of MOPPITT CO measurements. As remote CO2 sensors are evolving, a similar need has arisen. In this presentation we discuss in-situ CO2 measurements that have contributed to the validation of FTS measurements comprising part of the Total Carbon Column Observing Network, retrievals from AIRS, and presently the ACCLAIM and JPL LAS instruments. These remote observations will afford progress in our understanding of the carbon cycle, reducing the uncertainty in retrieved surface fluxes on regional scales.
