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 Dioxide 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 Dioxide Observation Method: TEMPO
The Tropospheric Emissions: Monitoring Pollution (TEMPO) instrument is a grating spectrometer sensitive to visible and ultraviolet wavelengths of light. It monitors major air pollutants such as ozone and nitrogen dioxide across the North American continent every daylight hour at high spatial resolution.
This Satellite Needs Working Group solution aims to provide hourly near real-time (NRT) air quality products using Tropospheric Emissions: Monitoring Pollution (TEMPO) and Geostationary Operational Environmental Satellite (GOES) data.
The 14 layers from the Tropospheric Emissions: Monitoring of Pollution mission offer data on clouds, nitrogen dioxide, ozone, and more.
More than a dozen Level 1, 2, and 3 data products from NASA's Tropospheric Emissions: Monitoring of Pollution (TEMPO) Version 03 collection are now available at provisional maturity.
