The OCO-3 program, developed by NASA, conducted a mission to monitor the Earth’s atmospheric carbon dioxide levels from the International Space Station. The data collected by the program will be used for better understanding of climate changes and identifying possible ways to mitigate its impact.

The OCO-3 program was launched on May 4, 2019 and attached to the exterior of the International Space Station. Its primary objective was to measure the absorption and scattering of sunlight by the Earth’s atmosphere and track the carbon dioxide around the world. The program will provide a detailed view of carbon dioxide concentration and identify the source of carbon dioxide emissions.

In addition to monitoring carbon dioxide levels, the program will also help scientists gain a better understanding of photosynthesis, which is the process by which plants use carbon dioxide to produce energy. The program will enable scientists to track the movement of carbon dioxide between different regions of the planet, providing insight into the global carbon cycle.

The data provided by the OCO-3 program will help countries around the world to develop better strategies for mitigating and adapting to climate change. The program is expected to collect data for approximately three years, with the possibility of an extension.
