TEMPO Air Quality Data 

This visualization shows NASA’s Tropospheric Emissions: Monitoring of Pollution (TEMPO) instrument’s measurements of elevated levels of nitrogen dioxide (NO2) from different areas and emission sources throughout the daytime on March 28, 2024. Yellow, red, purple, and black clusters represent increased levels of pollutants from TEMPO’s data and show drift over time. 

TEMPO gathers hourly daytime scans of the atmosphere over North America from the Atlantic Ocean to the Pacific Coast and from roughly Mexico City to central Canada. The instrument is an advanced spectrometer that detects pollution by observing how sunlight is absorbed and scattered by gases and particles in the troposphere, the lowest layer of Earth’s atmosphere.
