With other devices such as SAGE-III tracking ozone, ISS-LIS and ASIM monitoring lightning, and TSIS tracking the total energy flowing into Earth from the Sun, station experiments advance numerous climate records and models.

Algae play a major role in the global carbon cycle, and blooms are responsible for much of the ocean’s carbon absorption. Images taken by former space station payload HICO even helped develop an algorithm to detect Harmful Algal Blooms. coli bacteria that were modified to consume carbon dioxide as a food source. coli C5 studied the effect of microgravity on E. Photobioreactor examined whether microalgae could help close the carbon loop in life support systems, and Kuwait’s Experiment: E. “Our data are meant to help answer those kind of questions.”Ĭarbon storage and removal also has been investigated both inside and outside station. But there are still mysteries around how they do that, why the amount is different each year, and how absorption is going to happen in the future,” Eldering said. “Fortunately for us, the plants and ocean absorb about half of human-generated carbon dioxide emissions every year. Measuring those small changes could be key to answering long-standing questions about atmospheric carbon dioxide. But for carbon dioxide, it is uniquely difficult to see the changes,” Eldering said. “Most gases like ozone, carbon monoxide, or water vapor double or triple in atmospheric concentration when they are polluted, so it is pretty easy to detect. The OCO-3 sensor uses sunlight reflections through the atmosphere to measure variations in atmospheric carbon dioxide, observing changes of less than a single part per million. We have heard lots of discussion about how we can use all the data together to better understand plants.” Scientists who are thinking about plants and their role in the carbon cycle are super excited. And then there is GEDI, which is looking at how much plant material is on the ground.

“It turns out our space station neighbor ECOSTRESS is looking at how plants respond to stress. “The OCO-3 team wants to understand plants and their role in the carbon cycle,” said OCO-3 Project Scientist Annmarie Eldering of NASA’s Jet Propulsion Lab in Southern California. OCO-2, predecessor to OCO-3, data integrated into an atmospheric model shows atmospheric carbon dioxide levels over Earth. It is a fundamentally different data set than most other remote sensing instruments collect on free-flying satellites,” Stefanov said. “That orbit allows the space station to pass over different spots of Earth at different times of day or night and collect data. Its approximately 52 degrees of orbital inclination allows astronauts and Earth-observing payloads to see the sun rise and set 16 times each day across the world. The space station affords a unique planetary perspective with an orbital path passing over 90 percent of Earth’s population.

Its more than 20 years in orbit makes the space station a great place to collect this long-term data.

That means the factors influencing our climate must be tracked over long periods. Weather reflects the conditions of the atmosphere over a short period of time, and climate is how the atmosphere 'behaves' over decades, hundreds of years, or even geological time spans, Stefanov said.

“If you don’t have a good understanding of how things might change, you are in a very poor position to be able to handle it when they do,” said William Stefanov, manager of the Exploration Science Office at NASA’s Johnson Space Center in Houston. All of this work provides insight into the climate of our home and how we might prepare for coming changes. This outpost even conducts Earth science experiments. Astronauts take photos of the planet from the orbiting lab’s windows. Earth-observing CubeSats regularly deploy from the station’s airlock.
