Satellites have gotten much better at measuring greenhouse gases like carbon dioxide and methane. They can now map broad regional patterns and even spot individual leak sites. But we still have big blind spots, especially in the humid tropics, because frequent clouds make reliable measurements scarce. That limits our ability to track natural methane sources and regional carbon dioxide changes where they matter most.


Carbon-I is a proposed NASA mission designed to close these gaps. It would carry a highly sensitive near-infrared sensor to measure methane (CH4), carbon dioxide (CO2), and carbon monoxide (CO) over all land areas. The instrument can zoom in to tens of meters to pinpoint sources and also scan globally at a few hundred meters to map regions, helping us estimate how much gas is released or absorbed at the surface.


Beyond carbon science, Carbon-I’s wavelength range supports other benefits: identifying rock and soil minerals important for critical mineral assessments; sensing vegetation dryness linked to wildfire risk; and observing atmospheric water (including isotopes) to improve our understanding of regional to global water cycles. In short, Carbon-I aims to give a clearer, more complete picture of the carbon cycle while delivering practical co-benefits and numerous application areas.
