2025年1月23日 · CFCs are very stable chemical compounds, used in refrigerants, solvent, and (in the past in the U.S.) aerosols, which release chlorine (important) and fluorine (less important) into the upper atmosphere. In the stratosphere, CFCs are photolyzed (by incoming solar UV) to form carbon dioxide, CO2,

2025年1月23日 · NASA’s Earth science data reveal the effects of emissions such as carbon dioxide, methane, and other greenhouse gases on the planet and communities.

2025年1月23日 · HCFCs, 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

2025年1月23日 · Halons are a group of brominated organic compounds used as fire retardants. The transport of these compounds to the stratosphere, followed by their photolysis to release Br (Bromine) atoms, gives this group a very high ozone depletion potential. The production of these compounds is now banned accord

2025年1月17日 · The farming of aquatic organisms including fish, molluscs, crustaceans and aquatic plants with some sort of intervention in the rearing process to enhance production, such as regular stocking, feeding, protection from predators, etc. Also referred to as Mariculture - Marine fish farming (aquaculture

2 天之前 · Solar radiation is the total visible and invisible electromagnetic radiation emitted by the Sun. In a sense, NASA Earth science data comprises literally everything under the Sun.

Remote sensing plays a central role in the management of foreign policy.

chlorofluorocarbon (CFC) concentrations, permits higher amounts of ultraviolet radiation to enter the Earth's atmosphere, thereby posing risks to humans and ecosystems. Media attention to satellite images of the "ozone hole" heightened public concern about ozone depletion, leading to the Montreal Protocol on
