Earth Day Countdown Blog: T-17–Chemistry in the Atmosphere

04.05.2020
Air pollution can appear as a gray or orange haze enveloping a city. What the naked eye can’t see are the hundreds of chemical reactions taking place to produce that pollution. NASA science can reveal a more complete picture of atmospheric chemistry.

Earth Day Countdown Blog: T-22–Watching Levels of Sulfur Dioxide Pollution Drop

03.31.2020
Here’s a breath of fresh air: In the United States, levels of the toxic air pollutant sulfur dioxide have fallen by 90% since 1980, according to Environmental Protection Agency data from ground-based sensors.

Overview

The Atmospheric Chemistry and Dynamics Laboratory studies the ozone layer, a responsibility the Clean Air Act assigns to NASA. In addition, there is increasing concern about the global aspects of tropospheric pollution, and the coupling between chemical composition and climate.

One of the Laboratory's principal missions is to understand the behavior of stratospheric ozone and trace gases that influence ozone. Ozone and trace gases such as methane, nitrous oxide, and the chlorofluorocarbons profoundly influence Earth's habitability.

The Laboratory also studies the processes that control the composition of Earth's troposphere, the impact of human activity on global atmospheric pollution, and the impact of climate change on future concentrations of stratospheric ozone and tropospheric gases.
