OCO-2: WHAT'S NEW? . NASA Satellites Observe the Relentless Rise of Carbon Dioxide

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.

2023年8月12日 · What's New with OCO-2? A satellite gathering daily, detailed global measurements of the Earth's carbon, answering important questions about precisely where carbon is coming from and where it's being stored, to provide scientists with a better idea of how it is contributing to climate change.

The OCO-2 mission provides the highest quality space-based XCO2 retrievals to date. However, the instrument data are characterized by large gaps in coverage due to OCO-2’s narrow 10-km ground track and an inability to see through clouds and thick aerosols.

Orbiting Carbon Observatory-2 (OCO-2) is an American environmental science satellite which launched on 2 July 2014. A NASA mission, it is a replacement for the Orbiting Carbon Observatory which was lost in a launch failure in 2009.

2014年7月2日 · NASA's Orbiting Carbon Observatory-2 (OCO-2) was a replacement mission for the original OCO platform, which failed during launch. Launched on July 2, 2014, OCO-2 acquires space-based global measurements of atmospheric carbon dioxide (CO 2 ) with the precision, resolution, and coverage needed to characterize its sources and sinks (fluxes) on ...

2014年7月2日 · The Orbiting Carbon Observatory 2, or OCO-2, is an Earth satellite mission designed to study the sources and sinks of carbon dioxide globally and provide scientists with a better idea of how carbon is contributing to climate change.

2023年2月24日 · NASA’s Orbiting Carbon Observatory, 2 (OCO-2) provides the most complete dataset tracking the concentration of atmospheric carbon dioxide (CO₂), the main driver of climate change. Since its launch (July 2014), OCO-2 measures sunlight reflected from Earth’s surface to infer the dry-air column-averaged CO2 mixing ratio and provides around ...

Orbiting Carbon Observatory-2 (OCO-2) is NASA’s first dedicated Earth remote sensing satellite to study atmospheric carbon dioxide from space. OCO-2 is an exploratory science mission designed to collect space-based global measurements of atmospheric CO 2 with the precision, resolution, and coverage needed to characterize sources and sinks ...

2014年9月22日 · In July 2014, NASA launched the Orbiting Carbon Observatory-2 (OCO-2) mission. OCO-2 (described in this brochure) is the first NASA satellite dedicated to monitoring carbon dioxide, and it will do so with greater precision and detail than current instruments.
