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 ...
The pressure exerted by the atmosphere as a consequence of gravitational attraction exerted upon the 'column' of air lying directly above the point in question. Atmospheric Pressure | Earthdata The Earth Observing System Data and Information System is a key core capability in NASA’s Earth Science Data Systems Program.
Oct 21, 2019 · 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 and, hence, altitude in the atmosphere. Dry air ...

The Earth Observing System Data and Information System is a key core capability in NASA’s Earth Science Data Systems Program. It provides end-to-end capabilities for managing NASA’s Earth science data from various sources—satellites, aircraft, field measurements, and various other programs.
The biosphere encompasses all life on Earth and extends from root systems to mountaintops and all depths of the ocean. It is critical for maintaining species diversity, regulating climate, and providing numerous ecosystem functions. The biosphere is made up of the parts of Earth where life exists. It extends from the deep ocean floor, to lush ...
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 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 the cold upper troposphere located 8–15 km ...
May 12, 2023 · Incoming Solar Radiation. In general, solar radiation received at the earth's surface. The amount of direct solar radiation incident upon a unit horizontal surface at a specific level on or above the surface of the earth. Incoming solar radiation is solar radition that has not been scattered or absorbed.
