To accurately track CO₂ in the Earth's atmosphere, we need a global picture that is difficult to get from traditional air samples taken in just a few spots on the ground. It's like measuring the world's weather with only a handful of thermometers. Our new method uses the vast amount of data from NASA's OCO-2 satellite to see the whole atmosphere at once. This lets us measure how fast CO₂ is building up across the globe, providing results much faster and more frequently than ever before.
