3D Satellite Technology Reveals Danger of Wildfire Smoke Plumes, Enhancing Local Air Quality Warnings
In the face of escalating wildfire threats, a new era in air quality forecasting is upon us. Advances in smoke monitoring, as detailed in an article contributed to a website's Expert Voices: Op-Ed & Insights section, are offering more accurate and timely information to better protect public health.
These improvements are made possible by the use of satellite technology, particularly NASA's TEMPO satellite, launched in 2023. This innovative method provides a 3D mapping of smoke plumes with near real-time updates, a significant advancement over traditional reliance on ground-based air quality monitors.
For years, satellites have been used to track wildfire smoke plumes, but these satellites only provided two-dimensional views. The new satellite-based method, however, uniquely measures how much oxygen molecules absorb sunlight at a specific wavelength (688 nanometers), allowing scientists to determine the altitude of smoke plumes. This vertical information, combined with particle concentration data from NOAA's GOES-R satellites, enables more accurate assessment of health risks from smoke down to the neighborhood level, both in urban and rural areas.
This approach marks a significant advancement over traditional reliance on ground-based air quality monitors, which are sparse and often clustered in cities, leaving large areas without direct measurement. With TEMPO's data, forecasters gain a clearer, dynamic 3D picture of smoke movement, helping to identify which areas are most affected by hazardous smoke and improve air quality alerts and health advisories with much finer spatial resolution.
Systems that incorporate TEMPO data into machine learning models can map particulate matter (PM2.5) hourly, enhancing timely public health responses during wildfire episodes. While there remain limitations such as cloud interference and lack of nighttime data, this new satellite-enabled method represents a major leap forward in wildfire smoke surveillance and air quality forecasting across North America.
NOAA plans to incorporate TEMPO's height data into its AerosolWatch tool, which currently provides a near-real-time stream of wildfire smoke images from its GOES-R satellites. This integration will further enhance the tool's capabilities, providing even more detailed and accurate information to forecasters and public health officials.
As wildfire seasons continue to pose a significant threat to public health, these advancements in smoke monitoring and air quality forecasting are crucial in protecting millions of people across North America. The future of wildfire management lies in the integration of satellite technology and machine learning, ensuring a safer and healthier environment for all.
