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.

Nitrogen Oxides Data Access and Tools
Access 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 Earth observation (LANCE). While not intended for scientific research, NRT data are good resources for monitoring ongoing or time-critical events. Learn more about the difference between near real-time versus standard products.

Featured Nitrogen Oxides Observation Method: TROPOMI
The Tropospheric Monitoring Instrument (TROPOMI) is the single payload aboard ESA's Sentinel-5P spacecraft, providing daily measurements of cloud height and cover, aerosols, and trace gases such as nitrogen oxides.
Data from the next-generation Instruments will help atmospheric scientists advance air quality measurements and standards.
