Atmosphere - Earthdata
2024年10月10日 · Earth’s atmosphere is a thin veil of gas surrounding the planet. Although it only extends a few hundred kilometers above the surface, it contains a mixture of gases, such as oxygen and nitrogen, that are critical for life to exist. It distributes incoming solar radiation, protecting life from harmful ultraviolet radiation but also driving ...
Air Mass/Density | NASA Earthdata
Air mass/density is a fundamental property of atmosphere. Mixture of gases forming Earth's atmosphere, consisting of nitrogen (∼78%), oxygen (∼21%), water vapor, and other trace gases such as carbon dioxide, helium, argon, ozone, or various pollutants. The concentration of water vapor is very variable, being a strong function of temperature ...

Atmospheric Ozone | NASA Earthdata
Atmospheric 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 radiation, and is most potent as a greenhouse gas in ...
Earth Radiation Budget | NASA Earthdata
Earthdata Forum. The Earth Radiation Budget is the balance between incoming energy from the sun and the outgoing longwave (thermal) and reflected shortwave energy from the Earth. Definition source: National Aeronautics and Space Administration.
Lightning | NASA Earthdata
Lightning is the electrical discharge between positively and negatively charged regions within clouds. Visually, lightning is comprised of bright flashes of light called strokes. The loud sound of thunder that accompanies lightning is a sonic shock wave produced by the rapid expansion of the air surrounding the lightning channel during the ...
Atmospheric Water Vapor | NASA Earthdata
Atmospheric Water Vapor. (Also called aqueous vapor, moisture.) Water substance in vapor form; one of the most important of all constituents of the atmosphere.Air in motion relative to the surface of the earth. Definition source: National Snow and Ice Data Center.
Atmospheric Rivers | NASA Earthdata
Atmospheric Rivers. NASA’s Earth-observing satellites help scientists identify atmospheric rivers, which enables studies of climate change, water management, and weather. Atmospheric rivers are narrow, elongated corridors of concentrated moisture transport that occur in the lower atmosphere, ahead of the cold front in an extratropical cyclone.
Where Oceans Meet Atmosphere | NASA Earthdata
2020年12月28日 · Where Oceans Meet Atmosphere. Satellite data help sea-going oceanographers pursue an elusive ocean layer. On February 24, 2007, a storm hit the Research Vessel Knorr 1,200 kilometers (650 nautical miles) off the coast of Bermuda. Below decks, the crew listened as the fifty-foot waves and hurricane-force winds slammed into the ship.
Worldview | NASA Earthdata
Worldview is an easy-to-use visualization tool that allows users to interactively browse, compare, animate, and download over 1,200 visualized satellite data products. Many of those products are available within hours of being acquired—essentially showing the entire Earth as it looks "right now". This supports time-critical applications, such ...
