Atmospheric Pressure. 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.
Find Data. 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 ...
Global mean cloud top pressure data (observations of the atmospheric pressure at the top of a cloud) in millibars (mb) for July 2021 from the VIIRS Suomi NPP (SNPP) CLDPROPCOSP Level 3 monthly (M3), 1x1 degree grid data product. Orange and red colors indicate areas of higher pressure; blue and purple colors indicate areas of lower pressure.
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.
NASA's Land, Atmosphere Near real-time Capability for Earth observation (LANCE) supports users interested in monitoring a wide variety of natural and human-created phenomena using near real-time (NRT) data and imagery that are made available much quicker than routine processing allows. Most LANCE data products are available within 3 hours from ...
Feature Article. The radio occultation technique involves sending a radio signal from one navigation satellite to another through Earth’s atmosphere. Changes in atmospheric temperature, water vapor, pressure, and other characteristics slow or bend the path of the signal, which can be detected and interpreted to provide measurements. Credit: NASA.
Climate Indicators hold key information for the most relevant domains of climate change: temperature and energy, atmospheric composition, ocean and water as well as the cryosphere. Cryosphere The cryosphere encompasses the frozen parts of Earth, including glaciers and ice sheets, sea ice, and any other frozen body of water.
Explore Learning Resources. NASA’s massive archive of Earth science data are free and open to any user for any purpose—but accessing, analyzing, visualizing, and applying these data requires a certain degree of knowledge about Earth observation data and how it is collected and optimized. Check out our catalog of learning resources to better ...
Gases and solids injected into the stratosphere circled the globe for three weeks. Volcanic eruptions of this magnitude can impact global climate, reducing the amount of solar radiation reaching the Earth's surface, lowering temperatures in the troposphere, and changing atmospheric circulation patterns.
The product includes atmospheric temperature and water vapor profiles, surface temperature, cloud-top temperature/pressure, effective cloud optical depth, and effective cloud particle radius, and associated metadata. Further, the product is divided into a series of 6-minute time segments, or granules, with each granule making up one file.
