Abstract:
The NASA Orbiting Carbon Observatory-2 (OCO-2) successfully launched from Vandenberg Air Force Base in California on July 2, 2014. The OCO-2 mission is designed to provide remotely sensed measurements of the column averaged dry air mole fraction of carbon dioxide from space. OCO-2 is capable of making measurements in three observation modes: Nadir, glint and target. The standard operational mode for OCO-2 alternates between nadir and glint mode every 16 days, but target mode observations are possible by commanding the spacecraft to point to specific surface location. In this presentation we provide information on the preliminary observations and plans for OCO-2 2015. In particular, we will also provide an update on the pointing capabilities and accuracy for OCO-2. We provide updates on OCO-2 target mode including possible target mode locations. We will show calendars for the different viewing geometries and target mode possibilities.
