- Atmosphere - NASA Earthdata
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
- Humidity | NASA Earthdata
Humidity is a measure of water vapor in the atmosphere There are measures of absolute humidity, which is the grams of water vapor present per cubic meter of air Specific humidity is the grams of water per kilogram of air Then there’s the one people are most familiar with, relative humidity, which is the percentage of water vapor present in the air relative to the maximum it could hold at
- Level-1 and Atmosphere Archive and Distribution System Distributed . . .
NASA's Level-1 and Atmosphere Archive and Distribution System Distributed Active Archive Center primarily provides access to global science data products from MODIS and VIIRS
- Sun-Earth Interactions - NASA Earthdata
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
- Atmospheric Rivers - NASA Earthdata
NASA’s Earth-observing satellites help scientists identify atmospheric rivers, which enables studies of climate change, water management, and weather
- Atmospheric Temperature - NASA Earthdata
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
- Aerosol Optical Depth Thickness - NASA Earthdata
Aerosol optical depth (AOD) is an assessment of the amount of visible and infrared light aerosols scatter or absorb in a column of the atmosphere, and is sometimes referred to as aerosol optical thickness (AOT) AOD is a unitless measure From an observer on the ground, an AOD of less than 0 1 is characteristic of a clear sky, bright Sun, and maximum visibility As AOD increases to 0 5, 1 0
- Air Quality - NASA Earthdata
NASA's air quality data allow users to measure pollutants in the atmosphere and track their health and socioeconomic impact on people
