Earth Data: Air Quality

The NASA Earthdata Air Quality portal provides access to satellite observations, airborne measurements, ground-based data, models, and analytical tools that support air quality monitoring, research, and decision-making. The portal brings together a wide range of Earth observation datasets on aerosols, trace gases (including nitrogen dioxide, sulfur dioxide, carbon monoxide, and ozone), meteorological variables, land surface conditions, and human dimensions. It also includes data access tools, tutorials, webinars, GIS resources, and application guides to help users discover and use NASA Earth science data for air quality assessments.

The resource is designed for researchers, air quality practitioners, policymakers, and environmental agencies seeking to monitor pollution, assess population exposure, and support air quality management. It highlights NASA missions and products such as TEMPO, MODIS, VIIRS, OMI, AIRS, GEOS, and MERRA-2, and provides practical learning materials for applying Earth observation data to health assessments, emissions analysis, wildfire smoke monitoring, and policy evaluation. The portal is globally applicable and supports both operational and research applications in air quality management.
