*Why OCO-2 and GOSAT/ACOS?
Immediately after the loss of the first Orbiting Carbon Observatory (OCO) mission, the GOSAT Project Team in Japan invited the NASA OCO team to contribute to the GOSAT TANSO-FTS data analysis. To exploit this opportunity, NASA reconstituted the OCO team as the Atmospheric CO2 Observations from Space (ACOS) Task. The ACOS Task was formed by a number of institutions including the NASA Jet Propulsion Laboratory (JPL), the California Institute of Technology (Caltech), and Colorado State University. The ACOS task was terminated in September of 2012, while resetting the OCO-2 Team in preparation for the OCO-2 mission launch in 2014. The ACOS Version 3.3 data is released by the OCO-2 Team in June 2013.
