The Megacities project combines direct surface measurements of urban greenhouse gases from instruments located in air sampling stations atop radio towers and buildings, with broader, denser remote-sensing observations from aircraft, mountaintops and satellites. Other instruments track winds and vertical motion of the atmosphere -- both of which are key to interpreting the greenhouse gas measurements. NASA's recently launched Orbiting Carbon Observatory-2 (OCO-2) satellite is capable of detecting the enhanced levels of carbon dioxide over the world's largest cities and is beginning to study LA in coordination with the Megacities team.
