NOAA: “The coronavirus pandemic response has reduced pollution from a large number of sources across many geographic regions. NOAA has launched a wide-ranging research effort to investigate the impact of reduced vehicle traffic, air travel, shipping, manufacturing and other activities on Earth’s atmosphere and oceans. NOAA scientists are using the most advanced atmosphere-ocean models to look for changes in atmospheric composition, weather, climate, and precipitation over weeks to months. This research will provide important evaluations to improve weather forecasting and climate projections going forward…”
