This agreement involves scientists from National Oceanic and Atmospheric Administration (NOAA) who will perform a study outdoors to measure certain chemicals present in the air around Los Angeles. These chemicals, known as volatile organic compounds (VOCs), originate from various sources and can influence air quality. The researchers will employ a specialized tool capable of accurately analyzing these chemicals. They will then analyze the information gathered by this tool to determine the origins of these chemicals and how they transform over time due to sunlight and other factors. This knowledge will support government organizations in creating more effective regulations to decrease air pollution and enhance air quality in the coming years.
