Air pollution is a major concern for the health of our planet and its inhabitants. In recent years, there has been a growing need for accurate and real-time monitoring of air pollutants to address this issue effectively. NASA’s TEMPO (Tropospheric Emissions: Monitoring of Pollution) mission has emerged as a game-changer in this field. With its groundbreaking capabilities, TEMPO is set to revolutionize air pollution monitoring from space.
A New Era in Air Quality Monitoring
TEMPO, launched earlier this year on a SpaceX Falcon 9 rocket, is a space-based instrument designed to continually gauge air quality across North America. Situated at an orbit of 22,000 miles above the equator, TEMPO is the first of its kind to provide high-resolution data on major air pollutants at a resolution of a few square miles. This unprecedented level of detail allows scientists to study air quality patterns and identify pollution sources with remarkable accuracy.
The First Data Maps
NASA recently released the first data maps generated by TEMPO, marking a significant milestone in the mission’s progress. These maps provide valuable insights into the distribution of major air pollutants over North America. By monitoring pollutants such as nitrogen dioxide, TEMPO enables scientists to track pollution sources, measure their impact, and devise effective strategies to address air quality issues.
Monitoring Air Quality for a Sustainable Future
TEMPO’s mission aligns with the ambitious climate agenda set by President Biden and Vice President Harris. Their advocacy for improved air quality as a fundamental right resonates with TEMPO’s goal of supporting a cleaner and healthier environment for all citizens. By providing accurate and real-time data, TEMPO equips policymakers, researchers, and the public with the information needed to make informed decisions and take action towards achieving clean air.
Unraveling the Complexities of Air Pollution
Air pollution is a multifaceted problem influenced by various sources and factors. TEMPO’s capabilities extend beyond monitoring a single pollutant, nitrogen dioxide. This space-based instrument can measure several other pollutants that contribute to poor air quality. By examining the concentration and distribution of these pollutants, scientists gain a comprehensive understanding of the complexities of air pollution and its impact on our environment and health.
Tracking Nitrogen Dioxide Levels
Nitrogen dioxide (NO2) is a significant air pollutant produced by burning fossil fuels. It also plays a crucial role in the formation of other harmful pollutants. TEMPO’s data maps clearly depict hotspots of nitrogen dioxide around major cities. The levels of nitrogen dioxide fluctuate throughout the day, with higher concentrations during morning and evening rush hours when traffic emissions are at their peak. These observations provide valuable insights into the impact of transportation on air quality.

The Role of Consumer Products and Materials
While transportation has historically been a major contributor to air pollution, advancements in emissions standards for motor vehicles have led to notable improvements. However, the relative importance of consumer products and materials emitting volatile organic compounds (VOCs) has increased. VOCs combine with nitrogen dioxide in the air to form ground-level ozone, which remains a persistent problem in certain regions, particularly in California and major metropolitan areas.
Fine Particulate Pollution: A Lingering Challenge
Fine particulate pollution, known as PM2.5, poses significant health risks as these microscopic particles can enter our bloodstream and cause a range of respiratory and cardiovascular diseases. After years of decline, PM2.5 levels started increasing again around 2016. Wildfires, exacerbated by climate change, have been identified as a primary contributor to this reversal. The frequency and intensity of wildfires have risen, leading to a surge in fine particulate pollution.
TEMPO’s Impact on Air Pollution Research
TEMPO’s continuous monitoring and real-time data updates are expected to be a game-changer in the field of air pollution research. The ability to track air pollutants from their source with hourly updates will revolutionize our understanding of the dynamics and sources of pollution. Scientists will now have a more accurate and comprehensive understanding of how pollutants disperse and impact different regions, enabling them to develop targeted strategies for pollution mitigation and prevention.
The Promise of TEMPO’s Data
The data generated by TEMPO will not only benefit researchers and policymakers but also the general public. In spring 2024, the data will be made available to everyone, providing individuals with valuable insights into the air quality of their surroundings. This information empowers individuals to make informed decisions about their health, outdoor activities, and daily routines.
“We’re hoping to have better models and better prediction on the street level.”

Conclusion
NASA’s TEMPO mission is revolutionizing air pollution monitoring from space. By providing high-resolution, real-time data on major air pollutants, TEMPO equips scientists, policymakers, and the general public with the information needed to address air quality challenges effectively. With its game-changing insights and continuous monitoring capabilities, TEMPO is a significant step towards achieving clean air for all citizens. As we move forward, TEMPO’s data will play a vital role in shaping policies, driving innovation, and fostering a sustainable future for our planet.
