We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition. Read about the Web Unification Project

Carbon Monoxide Data Access and Tools

NASA has carbon monoxide datasets that help researchers characterize trace and major gases comprising Earth's atmosphere. Access a range of data and data tools such as AppEEARS, FIRMS, and Giovanni to make the most of carbon monoxide data.

Many NASA observation methods—platforms, instruments, and space geodesy techniques—provide data that improve our understanding of carbon monoxide in the atmosphere including the Tropospheric Emission Spectrometer (TES), Tropospheric Monitoring Instrument (TROPOMI), Measurement of Pollution in the Troposphere (MOPITT) instrument, and Microwave Limb Sounder (MLS) featured below.

Commonly Used Carbon Monoxide Data at a Glance

Descriptions of these measurements will be reviewed in more detail later in this Data Pathfinder. The following sections will help guide you to topic-specific data and resources for accessing, visualizing, preparing/manipulating (e.g. subsetting), and analyzing data. Each observation, model, and reanalysis data has unique characteristics that should be considered when evaluating its use.

An asterisk (*) next to an entry indicates that near real-time (NRT) data products are available through NASA's Land, Atmosphere Near real-time Capability for EOS (LANCE). While not intended for scientific research, NRT data are good resources for monitoring ongoing or time-critical events. To learn more about the difference between NRT and Standard Science Products, see Near Real Time versus Standard Products.

Featured Carbon Monoxide Observation Method: MLS

The Microwave Limb Sounder (MLS) flies aboard the Aura platform and is a passive microwave radiometer/spectrometer that measures vertical profiles of atmospheric gases, temperature, pressure, and cloud ice. MLS can detect carbon monoxide and its measurements are acquired globally day and night and can be obtained in the presence of ice clouds and aerosols. MLS data is often used in Stratospheric ozone layer stability, climate change, and air quality research. An MLS also was also aboard NASA’s Upper Atmosphere Research Satellite (UARS).
