Nasa world wind review9/25/2023 Collecting data from the sidewalks to satellites The campaigns may also have an opportunity to investigate another emerging air pollution source: wildfire smoke that has blanketed the Midwest and East Coast states this summer. These may not be properly accounted for in emission inventories or considered in air quality management strategies. As VOCs from the transportation sector have declined, recent NOAA research shows that consumer products derived from fossil fuels (so-called “volatile chemical products”) may now contribute as much as 50% of total petrochemical VOC emissions in densely populated urban cities. “In order to make progress on reducing air pollution that negatively affects millions of Americans, we need to have a better understanding of the current sources of pollutants and what happens to these pollutants once they are in the atmosphere,” said CSL scientist Carsten Warneke, one of the AEROMMA project’s mission scientists.įor decades, fossil fuel emissions were the primary source of urban volatile organic compounds or VOCs, which along with nitrogen oxides, or NOx, act as precursors to both ground-level ozone and particulate pollution. The largest, AEROMMA, has NOAA scientists and collaborators operating 30 specialized instruments aboard NASA’s DC-8 flying laboratory, collecting a myriad of chemical measurements over highly populated cities, including New York City, Chicago, Toronto and Los Angeles. Scientists from four NOAA research labs, led by the Chemical Sciences Laboratory (CSL), along with NOAA satellite scientists and research pilots, are leading three of the research projects. After decades of decline in ground-level ozone and fine particulate matter in the U.S., downward trends have slowed in recent years. Sixty-nine counties are failing to meet the standard for fine particulates, or PM2.5, set in 2006. counties as failing to meet the 8-hour ozone standard established in 2015. Probing the causes of persistent pollutionĮPA, which sets national air quality regulations, currently lists about 200 U.S. Lessons learned will aid the development of the new GeoXO satellites being jointly developed by NOAA and NASA. The data will also be used to evaluate the first observations made by NASA’s groundbreaking TEMPO offsite link instrument - the first geostationary space-borne sensor to continuously measure air pollution across North America. Findings will be shared with state and local environmental officials to inform decisions about the most effective ways to reduce air pollution. Environmental Protection Agency (EPA) in an effort to improve air pollution forecasts. The data will be scrutinized, analyzed and run through sophisticated chemical and weather models by scientists and the U.S. Using multiple satellites, seven research aircraft, vehicles, dozens of stationary installations - even instrumented backpacks - scientists will measure air pollution from sources that include transportation, industrial facilities, agriculture, wildfires and consumer products such as paint, pesticides and perfumes.
