Status: Current, Extended Mission
Mission Category: Earth System Science Pathfinder Program, A-Train
Launch Date: July 2, 2014
Launch Location: Vandenberg Air Force Base, CA
Designed Life: July 2, 2019

The second Orbiting Carbon Observatory (OCO-2) mission is designed to provide space-based global measurements of atmospheric carbon dioxide with the precision and resolution needed to identify and characterize the processes that regulate this important greenhouse gas. With its three high-resolution grating spectrometers, data collected by OCO-2 could be combined with meteorological observations and ground-based carbon dioxide measurement to help characterize carbon dioxide sources and sinks on regional scales at monthly intervals for 2 years.
