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.
