Data Overview

Our Data

A critical component of Carbon Mapper’s mission is to persistently pinpoint, quantify and track strong methane and carbon dioxide (CO2) emissions at facility scale and to make this data free and open to the public, providing accessibility and transparency to maximize impact. With its satellite plus airborne monitoring technology, Carbon Mapper shines a spotlight on where, when, and how methane and CO2 emissions are released. Its independent, facility-scale data insights increase global accessibility, transparency, and understanding of methane and CO2 data, unlocking a host of new solutions to operators, regulators, and civil society to reduce the amount of methane emissions escaping into the atmosphere.


Currently, the Carbon Mapper data portal is under development. Once available, it will allow users to explore, analyze, and download point source methane data as collected by the Carbon Mapper research team in select US regions since 2016. Over the next two years, the portal will be periodically updated with new data sets from future airborne methane surveys. By early 2023, the portal will be upgraded in preparation for ongoing data delivery from our satellite constellation within 90 days of observation.

In the meantime, please visit the prototype data portal at, a respository of multi-scale methane data for California and the Permian Basin, originally developed by our colleagues at NASA’s Jet Propulsion Laboratory and members of the Carbon Mapper team.

The Carbon Mapper data systems and the underlying algorithms have benefited from five years of development under several NASA-funded programs including the Carbon Monitoring System (CMS), ACCESS, and Advanced Information Systems Technology (AIST) programs. Those projects have improved the accuracy, efficiency, and utility of methane and CO2 data products and analytics. Several of these research programs are ongoing and will be infused into future versions of the Carbon Mapper data portal. Some of this technology has been made available to the California Air Resources Board to support its California-specific methane data portal.
