NASA has made new information obtainable that may present air air pollution observations at unprecedented resolutions – right down to the dimensions of particular person neighborhoods. The close to real-time information comes from the company’s TEMPO (Tropospheric Emissions: Monitoring of Air pollution) instrument, which launched final 12 months to enhance life on Earth by revolutionizing the way in which scientists observe air high quality from area. This new information is out there from the Atmospheric Science Information Middle at NASA’s Langley Analysis Middle in Hampton, Virginia.
“TEMPO is one in every of NASA’s Earth observing devices making big leaps to enhance life on our house planet,” mentioned NASA Administrator Invoice Nelson. “NASA and the Biden-Harris Administration are dedicated to addressing the local weather disaster and making local weather information extra open and obtainable to all. The air we breathe impacts everybody, and this new information is revolutionizing the way in which we observe air high quality for the good thing about humanity.”
The TEMPO mission gathers hourly daytime scans of the environment over North America from the Atlantic Ocean to the Pacific Coast, and from Mexico Metropolis to central Canada. The instrument detects air pollution by observing how daylight is absorbed and scattered by gases and particles within the troposphere, the bottom layer of Earth’s environment.
“All of the pollution that TEMPO is measuring trigger well being points,” mentioned Hazem Mahmoud, science lead at NASA Langley’s Atmospheric Science Information Middle. “We’ve greater than 500 early adopters utilizing these datasets immediately. We anticipate to see epidemiologists and well being specialists utilizing this information within the close to future. Researchers finding out the respiratory system and the impression of those pollution on individuals’s well being will discover TEMPO’s measurements invaluable.”
An early adopter program has allowed policymakers and different air high quality stakeholders to grasp the capabilities and advantages of TEMPO’s measurements. Since October 2023, the TEMPO calibration and validation staff has been working to guage and enhance TEMPO information merchandise.

“Information gathered by TEMPO will play an necessary function within the scientific evaluation of air pollution,” mentioned Xiong Liu, senior physicist on the Smithsonian Astrophysical Observatory and principal investigator for the mission. “For instance, we can conduct research of rush hour air pollution, linkages of illnesses and well being points to acute publicity of air air pollution, how air air pollution disproportionately impacts underserved communities, the potential for improved air high quality alerts, the consequences of lightning on ozone, and the motion of air pollution from forest fires and volcanoes.”
Measurements by TEMPO embrace air pollution resembling nitrogen dioxide, formaldehyde, and ground-level ozone.
“Poor air high quality exacerbates pre-existing well being points, which results in extra hospitalizations,” mentioned Jesse Bell, government director on the College of Nebraska Medical Middle’s Water, Local weather, and Well being Program. Bell is an early adopter of TEMPO’s information.
Bell famous that there’s a lack of air high quality information in rural areas since monitoring stations are sometimes tons of of miles aside. There may be additionally an observable disparity in air high quality from neighborhood to neighborhood.
“Low-income communities, on common, have poorer air high quality than extra prosperous communities,” mentioned Bell. “For instance, we’ve performed research and located that in Douglas County, which surrounds Omaha, the jap facet of the county has greater charges of pediatric bronchial asthma hospitalizations. Once we establish what populations are going to the hospital at the next charge than others, it’s communities of shade and folks with indicators of poverty. Information gathered by TEMPO goes to be extremely necessary as a result of you may get higher spatial and temporal decision of air high quality throughout locations like Douglas County.”
Figuring out sources of air air pollution will be tough as smoke from wildfires or pollution from trade and visitors congestion drift on winds. The TEMPO instrument will make it simpler to hint the origin of some pollution.
“The Nationwide Park Service is utilizing TEMPO information to achieve new perception into rising air high quality points at parks in southeast New Mexico,” defined Nationwide Park Service chemist, Barkley Sive. “Oil and gasoline emissions from the Permian Basin have affected air high quality at Carlsbad Caverns and different parks and their surrounding communities. Whereas air pollution management methods have efficiently decreased ozone ranges throughout many of the United States, the info helps us perceive degrading air high quality within the area.”
The TEMPO instrument was constructed by BAE Techniques, Inc., House & Mission Techniques (previously Ball Aerospace) and flies aboard the Intelsat 40e satellite tv for pc constructed by Maxar Applied sciences. The TEMPO Floor System, together with the Instrument Operations Middle and the Science Information Processing Middle, are operated by the Smithsonian Astrophysical Group, a part of the Middle for Astrophysics | Harvard & Smithsonian.
