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 ...
Drill down to the data and tools you need by exploring platforms on Earth and in the sky. From the ground and into space, instruments aboard NASA platforms collect a vast array of Earth science data. These data are used to support scientific and societal applications Earth observations, positioning, navigation, and timing.
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 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 ...
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.
Download PDF. In a bustling room in Fairbanks, Alaska, a group of researchers watched two blips move eastward on a map of the Arctic. After an eight-hour flight collecting atmospheric data over northern Canada, the blips—two airplanes riddled with sensors—had almost reached Thule, Greenland. Jennifer Olson, an atmospheric chemist, worked on ...
Atmospheric Radiation. Radiation budget refers to the difference between the absorbed solar. radiation and the net infrared radiation. The radiation budget takes into. account the sum of all radiation, transferred in all directions, through. the Earth's atmosphere and to and from space. The radiation budget (or.
Prithvi-weather-climate (Prithvi-WxC) is a weather and climate foundation model (FM) pre-trained on Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2) data from NASA's Global Modeling and Assimilation Office to replicate atmospheric dynamics while being capable of dealing with missing information.
One of the major greenhouse gases. Atmospheric carbon dioxide is caused mainly by the burning of fossil fuels and deforestation. The chemical formula for carbon dioxide is CO2. Long-term measurements of CO2 in the atmosphere are conducted at Manua Loa, Hawaii and several international monitoring stations around the world.

Sun-Earth Interactions. NASA collects data on the Sun and its energy to understand how our closest star impacts Earth's energy fields, atmosphere, weather, and human activity. Every moment of the day, Earth receives 10,000 times more energy from the Sun than the entire planet uses across our various power systems.
