Bookmark or Share- Hydrochlorofluorocarbons | NASA EarthdataHCFCs, with one or more hydrogen-carbon bonds are slated to replace CFCs in most of the current applications. HCFCs are more unstable and subject to hydroxyl radical and ozone attack early in their gas phase career in the atmosphere. Therefore, their atmospheric lifetime is projected to be shorter a

- Industrial Emissions | NASA EarthdataGHGs include carbon dioxide, methane, nitrous oxide, chlorofluorocarbons (CFCs), ozone (O 3), and water vapor (H 2 O). Remotely sensed greenhouse gas data, such as the data collected by NASA’s Earth-observing satellites, are used in atmospheric models to estimate the sources and sinks of these gases.
- Atmospheric Ozone | NASA EarthdataAtmospheric Ozone is one of the most important trace gases in our atmosphere that both benefits and harms life on Earth. High ground-level ozone amounts contribute to poor air quality, adversely affecting human health, agricultural productivity, and forested ecosystems. Ozone absorbs infrared radiat
- Volcanoes and Climate Change | NASA EarthdataFor instance, chlorofluorocarbons (CFCs) in the atmosphere start a chain of chemical reactions on aerosol surfaces that destroy ozone molecules in the mid-latitude stratosphere, intensifying observed stratospheric ozone depletion.
