These traces provided an unexpected window into what low-emissions world could look like, thus providing a means for identifying effective environmental policies. While many countries in the last few decades have implemented environmental policies to reduce human health risk from air pollution by controlling emissions, the impacts of those policies have not always been clear. The global lockdowns in response to COVID-19 represent a well-observed “scenario-of-opportunity” that allows us to assess how atmospheric emission and composition responds to reduced human activity. COVID-19 lockdowns effectively showed how reducing NOx emissions affects the global atmosphere. Its identifying signature shows up as in the atmosphere’s altered ability to produce harmful ozone pollution and ozone’s reduced influence on Earth’s heat balance that affects climate. These effects are not uniform across the world and depend on the location and season of the emission reductions.The results of this research indicate that in order to design effective environmental policies which benefit both air quality and climate, decision-makers need to carefully consider the complex relationships between emissions and atmospheric composition. || ", "release_date": "2021-12-13T00:00:00-05:00", "update_date": "2025-02-18T00:11:37.164420-05:00", "main_image": { "id": 374810, "url": "https://svs.gsfc.nasa.gov/vis/a000000/a004900/a004959/o3_2d.01350_print.jpg", "filename": "o3_2d.01350_print.jpg", "media_type": "Image", "alt_text": "Ozone reductions corresponding to emission decreases from lockdowns in each region of the world show distinct patterns, both locally where the lockdowns occurred and remotely due to the global circulation of the atmosphere. The results demonstrate that where and when the lockdowns occurred is very important in determining the impact on atmospheric composition.\r\rTo identify regional and seasonal changes in the ozone response, the team conducted model simulations for each region separately. For each model simulation shown here, only the NOx reductions for that region were used, leaving the rest of the globe at the status quo. This allowed the investigators to avoid seeing overlapping effects from more than one region at once.\r\rEach region shows distinct patterns: \r\rOzone production from NOx is most efficient in the tropics because of warmer and sunnier climate. \r\rThe South American emission reductions result in a long tail of decreased ozone along the mid-latitude westerlies in the Southern Hemisphere.\r\rThe European and Australian emission influences on ozone are mostly limited to the region poleward of 30°, linked to the movements of large air masses, like cold or warm fronts, that scale thousands of miles. \r\rOverall, the lockdowns in the northern midlatitudes had the largest impact on ozone concentrations because reductions in NOx emissions were largest there. \r", "width": 1024, "height": 576, "pixels": 589824 } } ], "products": [], "newer_versions": [], "older_versions": [], "alternate_versions": [] }
