A New Pole Hole - NASA Earthdata Indeed, governments signed an international treaty in 1989 that banned production of chlorofluorocarbons (CFCs) and other ozone-destroying chemicals And data show that chlorine in the stratosphere has started to decline
Industrial Emissions | NASA Earthdata GHGs 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
Dr. Qing Liang - NASA Earthdata Dr Qing Liang, Research Physical Scientist, Atmospheric Chemistry and Dynamics Laboratory, NASA's Goddard Space Flight Center, Greenbelt, Maryland Research Interests: Investigating the atmospheric budget and the transport of trace gases (e g , human-made chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and the naturally emitted, short-lived halogen compounds) that impact
Operation IceBridge - NASA Earthdata Operation IceBridge was an airborne campaign that surveyed the Arctic, Antarctica, and Alaska over a period of 10 years IceBridge provided essential data on the height, depth, thickness, and flow of sea ice, glaciers, and ice sheets Learn More About Operation IceBridge
Salt of the sea - Earthdata Salt afects buoyancy Saltier, denser water sinks and fresher, less dense water floats, causing verti-cal and horizontal currents within the oceans Winds move upper-ocean currents, but the real engine behind deep-water currents is density, and that is driven by temperature and salinity difer-ences of water masses Density shifts might speed up or slow down currents and cause water masses to
Weathering - NASA Earthdata NASA's weathering data reveal how the interaction of rocks, minerals, and soil with the atmosphere changes Earth's surface over time
LAADS DAAC - Earthdata Learn about accessing and downloading atmospheric data from NASA's LAADS DAAC through a comprehensive webinar presentation
Atmospheric Science Data Center | NASA Earthdata NASA's Atmospheric Science Data Center projects focus on Earth science disciplines including radiation budget, clouds, aerosols, and tropospheric composition
