The Most Important Satellite You’ve (Probably) Never Heard Of

Quick Overview

The Orbiting Carbon Observatory (OCO) satellites, specifically OCO-2 and OCO-3, are NASA's crucial tools for monitoring Earth's carbon dioxide levels, providing highly detailed global data that is vital for understanding climate change and improving carbon cycle models. Despite an initial setback with OCO-1, subsequent missions have successfully provided continuous, high-resolution measurements, enabling scientists to track CO2 sources and sinks with unprecedented accuracy, which is essential for informed climate policy and research.

Key Points: NASA's Orbiting Carbon Observatory (OCO) satellites, OCO-2 and OCO-3, are designed to measure atmospheric carbon dioxide (CO2) concentrations globally. The OCO program provides high-resolution data crucial for understanding the carbon cycle and climate change. OCO-1 failed during launch in 2009, but OCO-2 was successfully launched in 2014 and OCO-3 was deployed in 2019. OCO-2 and OCO-3 measure CO2 by observing how sunlight reflects off Earth's surface and is absorbed by atmospheric gases. The data collected by OCO satellites helps scientists pinpoint CO2 sources and sinks, monitor seasonal variations, and improve climate models. The information is vital for assessing the impact of human activities on the atmosphere and for developing strategies to mitigate climate change.

Context: The Orbiting Carbon Observatory (OCO) program is a series of NASA missions dedicated to monitoring the Earth's atmosphere, specifically focusing on carbon dioxide (CO2) levels. The goal is to provide precise, global measurements of CO2 to help scientists better understand its distribution, sources, and sinks, and how it influences climate change. The first satellite, OCO-1, tragically failed during launch in 2009. However, the program continued, leading to the successful launch of OCO-2 in 2014 and OCO-3 in 2019. These satellites use advanced spectroscopy to measure CO2 concentrations, providing data that is essential for climate modeling and policy-making.
