The Orbiting Carbon Observatory is scheduled for launch in September 2008. The space-based observatory will
sample the dry air, column averaged mole fraction of CO2 (Xco2) based on analysis of reflected solar radiation
acquired by three grating spectrometers. We will describe plans and progress to date of the OCO validation
program, which consists primarily of a series of ground-based, Fourier Transform Spectrometers, that measure
Xco2 in the same spectral regions as the space-based spectrometers. Site selection and procedures for
ensuring self-consistency among measurements of the ground-based network will be described. The goal of the
OCO validation program is to detect and mitigate any geographically coherent biases, on regional to continental
scales, in the space-based retrievals of Xco2 that may affect the accuracy of carbon fluxes inferred from the
space-based measurements.
