  "account": "NASA-led air quality research in Addis Ababa, Ethiopia's capital, has yielded detailed long-term data on the impact of black carbon, or soot, produced by various combustion sources. The research, conducted from 2022 to 2025 using 10 ground-based sensors deployed by NASA's Multi-Angle Imager for Aerosols (MAIA) project, reveals how pollution levels fluctuate based on time of day and season. The findings, published in the journal ES&T: Air, are relevant to cities worldwide, including those in the United States. Ethiopia recently banned the import of internal combustion engine vehicles and is expanding bike lanes and electric vehicle infrastructure. The study focuses on PM2.5, which is linked to about 4.9 million global deaths annually. Black carbon, a type of PM2.5, was found to be four to nine times higher in Addis Ababa than in three U.S. cities monitored by the mission. This is the first long-term, multisite study of continuous PM2.5 and black carbon measurements in Ethiopia, providing a valuable baseline for understanding pollution changes in the rapidly growing city.",
  "summary": "A NASA-funded air pollution monitoring network has provided one of the most detailed long-term views yet of the role of black carbon, or soot produced by fires, diesel vehicles, and other combustion sources, in Ethiopia’s capital, Addis Ababa. The detailed measurements show how pollution changes by time of day and season, including increases associated with […] The post NASA Mission Studies Air…",
