The recent release of NASA’s TEMPO (Tropospheric Emissions: Monitoring of Pollution) satellite images has shed light on the alarming levels of air pollution plaguing major urban areas across North America. Launched in April, the satellite has been orbiting the Earth at an altitude of 22,000 miles, capturing high-resolution images of air pollution with unprecedented accuracy. TEMPO’s innovative technology allows it to measure air pollution down to a few square miles, tracking changes in pollution levels in short time frames.
The TEMPO satellite is revolutionizing our understanding of environmental health by providing valuable data on air pollution to decision-makers, policymakers, and the general public. Its real-time tracking capabilities aim to enhance our comprehension of environmental health and aid in the development of strategies to improve air quality. The satellite’s data will also empower everyday Americans to access and utilize information to monitor and improve the quality of the air they breathe.
The initial images released by TEMPO showcase the levels of nitrogen dioxide in the air around major urban centers, including Los Angeles, New York, Washington, Houston, and New Orleans. Darker colors represent higher levels of pollution, providing a stark visual representation of the severity of air pollution in these regions. These visualizations offer valuable insights into air quality, highlighting the significance of TEMPO’s data in enhancing our understanding of environmental health.

TEMPO’s groundbreaking technology utilizes a spectrometer to measure pollution by analyzing the wavelengths of light absorbed by gases in the atmosphere. In its full operations, the satellite will take hourly scans during daylight hours, covering an area from central Canada down to Mexico City. This technology enables TEMPO to gather data on a range of pollution levels, including ozone, nitrogen dioxide, formaldehyde, aerosols, water vapor, and trace gases.
The importance of TEMPO’s mission cannot be overstated. Poor air quality has significant impacts on human health, with many Americans having personally experienced its effects, particularly during forest fire seasons. TEMPO’s data will help policymakers and community leaders develop more effective strategies for improving air quality and mitigating the impacts of pollution on human health. With TEMPO’s game-changing technology, NASA and the Biden-Harris Administration are committed to making it easier for everyone to access and use data to monitor and improve the quality of the air they breathe.
As TEMPO continues to collect and share its data, its findings will undoubtedly have far-reaching implications for our understanding of air pollution and its effects on the environment and human health. With its unparalleled resolution and precision, TEMPO is poised to revolutionize the field of environmental monitoring, providing valuable insights that will benefit generations to come. The TEMPO satellite’s groundbreaking technology has the potential to transform our understanding of environmental health, empowering policymakers and the general public to take action against the increasing threat of air pollution in North America.
