Earth's atmosphere is a layer of mixed gases approximately 60 miles high that provides the air we breathe, shields us from dangerous levels of ultraviolet light from the sun, and traps enough heat to maintain a livable environment. NASA's satellites make atmospheric measurements that scientists use to study its chemistry and air quality, weather, and climate change. We have thousands of data ...
Condensation heat transfer is a critical process in many industrial applications, from power generation to chemical processing, where efficiency and performance are paramount. In the presence of ...

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 variab
Clouds are made of water and or ice, come in more than a dozen types, and range in altitude from ground level to 280,000 feet high in Earth’s atmosphere. They water our lands, are part of the fury of hurricanes, both warm and cool the planet, and at times, interfere with completing important observations or tasks.
Temperature can vary greatly at different levels of Earth's atmosphere. Measuring atmospheric temperatures is essential for many forms of scientific work including weather forecasting and studying climate processes, and for conducting human activities such as flying aircraft, agriculture, and controlling pollution. NASA collects atmospheric temperature data using ground, airborne, and space ...
