To everyone critical of my statement, have a look yourself:

https://svs.gsfc.nasa.gov/5022

The same seasonal patterns play over and over with very little precision or interesting insights from 2015-2022.

"However, the OCO-2 data as observed by the on-board instrument have large data gaps in coverage due to the narrow 10-km ground track and an inability to see through clouds and aerosols. To provide a gap-filled view of Earth’s carbon cycle and atmosphere NASA’s Global and Modeling Assimilation Office (GMAO) ingests OCO-2 retrievals every 6 hours with a modeling and assimilation technique and derives the Gridded Monthly OCO-2 Carbon Dioxide/OCO-2 GEO"

It can't measure through clouds which is 2/3 of the earth's atmosphere at any given time. Ground based or flight based instrumentation is absolutely superior for this, and CO2 is already well mixed in the atmosphere so it provides very little insight to keep it going for whatever millions it is costing to run.

As I mentioned before the brigade, Moana Loa Observatory and others like it provide far more accurate data and have much more consistent data.

Here is the quote above with additional context :-

"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 100,000 cloud-free observations.

However, the OCO-2 data as observed by the on-board instrument have large data gaps in coverage due to the narrow 10-km ground track and an inability to see through clouds and aerosols. To provide a gap-filled view of Earth’s carbon cycle and atmosphere NASA’s Global and Modeling Assimilation Office (GMAO) ingests OCO-2 retrievals every 6 hours with a modeling and assimilation technique and derives the Gridded Monthly OCO-2 Carbon Dioxide/OCO-2 GEOS Level 3 product."

According to your source, the satellite provides the most complete dataset.

This observatory is also being shut down.

But the change in reflected vs captured radiation is exactly what causes global warming, no?

>The satellite actually performed a lot better than anyone was expecting, becoming the "gold standard" in space-based carbon dioxide measurements.

>"The mission has also uncovered insights into CO2 emissions from cities, and contributes data supporting the Paris Agreement," NASA's Jet Propulsion Laboratory adds. "As an unexpected bonus, OCO-2 has even been able to track growing seasons and crops by measuring the 'glow' plants emit when they photosynthesize."

>Data produced by the satellite has been used to create maps of photosynthesis on Earth, providing useful data to farmers as well as scientists, as they monitor farmland, crop yield, and drought.
