SAN DIEGO — No matter the build on Earth you dwell, there’s liable to be an look for in the sky hovering over you. That’s a appropriate element, a minimal of in phrases of satellite tv for computer monitoring of air quality, acknowledged scientists from the Nationwide Aeronautics and Condominium Administration, acknowledged as NASA.
In a varied symposium held at the American Thoracic Society (ATS) 2024 World Conference, NASA health and air quality specialists described the employ of field-basically basically based methods and earth science applications to toughen working out of respiratory health risks worldwide and to support enrich pulmonary research with galaxies of data.
“On daily basis we win over 25 terabytes of data,” acknowledged John Haynes, MS, program supervisor for Health and Air Quality Functions in the Earth Action Program, Earth Sciences Division, NASA, in Washington, DC.
“Many of the observation datasets are essential for healthy air quality applications: Commentary of land floor temperature, sea floor temperature, precipitation, fires and thermal anomalies, aerosols, faithful to name about a. And the basically awesome data is this offering from our constellation of satellites is free and inaugurate assemble admission to, on hand to all people across the globe,” he acknowledged.
The mission of NASA’s Earth Action Program is “to enable folk and organizations to put collectively insights from Earth science to support the financial system, health, quality of existence, and atmosphere.”
Program workers work with both industry and nonprofit environmental advocacy and health teams to support dispute their decisions and actions with Earth science data.
NASA supports the employ of Earth observations to support video show and space up infectious diseases and environmental health, toxins and pathogens which possess an affect on health, and air quality requirements and to evaluate the outcomes of climate commerce on air quality and public health.
Haynes eminent that worldwide, six predominant cities possess included NASA data on elegant particulate matter smaller than 2.5 µm (PM2.5) into their climate scamper plans. These cities encompass Accra, Ghana; Addis Ababa, Ethiopia; Buenos Aires, Argentina; Guadalajara, Mexico; Lima, Peru; and Johannesburg, South Africa.
Monitoring Air pollution With Tropospheric Emissions: Monitoring of Air pollution (TEMPO)
There are more than 30 Earth-monitoring methods at demonstrate in orbit or soon to be launched, including NASA’s TEMPO, launched in April 2023. Its first operations, or “break of day” in field keep in touch, began in August 2023. The instrument is in a geostationary orbit about 22,236 miles above the equator at longitudes that enable it to search practically about all of North The united states — from hover to hover and from southern Mexico, Cuba, Puerto Rico, and the Bahamas to Northern Canada.
TEMPO is fragment of a geostationary air quality satellite tv for computer “constellation” or neighborhood that affords sunlight hours observation over your total Northern Hemisphere, explained Aaron Naeger, PhD, MS, mission applications lead for TEMPO at the NASA Marshall Condominium Flight Center in Huntsville, Alabama. Until TEMPO, field-basically basically based instruments had rather low spatial decision and can simplest capture one image day after day.
In incompatibility, TEMPO can scan East-West continuously every sunlight hours hour across a total protection condominium (acknowledged as the Self-discipline of Regard) and even more assuredly throughout early morning and leisurely afternoon. This lets in researchers to measure volumes of pollution, sources, and variation of pollution phases over time. The gadget measures ozone phases, nitrogen dioxide (NO2), formaldehyde, and aerosols.
Larger than 100 federal, impart, local, and tribal air quality companies employ the info captured by TEMPO to explain public health efforts.
Naeger gave examples of how the gadget can support establish public health hazards. For instance, scans over Texas on November 1, 2023, showed excessive NO2 phases from cities, web page visitors corridors, vitality vegetation, oil and gasoline fields, and fires. Similarly, the gadget detected unhealthy ozone and PM2.5 phases throughout prescribed burns in April 2024. The gadget furthermore chanced on famous variations between weekdays and weekends in NO2 concentrations across California and the Entrance Range in Colorado, including greater phases alongside web page visitors corridors throughout weekdays due to greater web page visitors volume and tailpipe emissions.
Fire and Heat
Diversified NASA health and air quality initiatives encompass the FireAQ challenge, basically basically based at the University of Iowa in Iowa City, Iowa, which affords free on-line weekly briefings on fire-linked air quality concerns the employ of recordsdata from TEMPO and varied NASA satellite tv for computer methods. The challenge used to be described by Jun Wang, PhD, from the University of Iowa.
NASA furthermore fosters collaborations to decrease health disparities in air quality and respiratory health in metropolis heat islands and varied areas tormented by coarse temperatures due to climate commerce, as discussed by Christopher Ok. Uejio, PhD, from Florida Declare University in Tallahassee, Florida.
Air pollution professional George D. Thurston, ScD, professor of medication and inhabitants health at the NYU Grossman College of Medicines, NYU Langone Health, Recent York City, who attended the session, commented that the PM2.5 commonplace comprises unhazardous particulate matter, such as soil, and misses submicron-sized particles and requested Haynes whether measurements of smaller particles had been being measured in the reviews he described.
Haynes spoke back that the methods assemble now not straight away measure PM2.5 but as a alternative rely on aerosol optical depth, a measure of the extent to which atmospheric particles soak up or scatter sunlight hours.
Thurston, who in 1987 used to be coauthor of groundbreaking behold displaying the hyperlink between PM2.5 phases and mortality, is now an advocate for a more difficult commonplace of measuring ambient ultrafine particles with an aerodynamic diameter lower than 1 µm in dimension.

Haynes and Naeger are both NASA workers. Thurston had no linked disclosures.
