Air Mass/Density | NASA Earthdata
17 Dec 2025 at 8:06am
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.

Hurricanes - NASA Earthdata
12 Dec 2025 at 10:45pm
Hurricanes are one of the largest hazards to life and property on Earth. Hurricanes are a rotating, tropical cyclone with a low pressure center (the eye) and 1-min average surface (10 m) winds in excess of 32 m s?1 (64 knots) in the Western Hemisphere. This area encompasses the North Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and the eastern and central North Pacific east of the ...

Atmosphere - NASA Earthdata
17 Dec 2025 at 6:04am
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.

For example, temperature and pressure are variables of the atmosphere. Parameters and variables can be used interchangeably. Variable level attributes provide individual information for each variable. The Name in this table is the variable name. Fill value indicates missing or undefined data points in a variable.

Convert Water Vapor Mixing Ratio to Precipitable Water Vapor
15 Dec 2025 at 10:20pm
Learn how to use AIRS soundings to determine the amount of precipitable water vapor in the atmosphere and predict whether a storm will increase in intensity.

This dataset provides daily-averaged atmosphere surface temperature, humidity, winds, and pressure on the native Lat-Lon-Cap 90 (LLC90) model grid from the ECCO Version 4 Release 4 (V4r4) ocean and sea-ice state estimate.

Airborne Vertical Atmospheric Profiling System | NASA Earthdata
17 Dec 2025 at 7:47pm
The Airborne Vertical Atmospheric Profiling System (AVAPS), also known as the AVAPS Dropsonde System, is a key atmospheric instrument that measures high resolution vertical profiles of ambient temperature, pressure, humidity, wind speed and wind direction. Measurements are taken by a parachuted GPS dropsonde that is launched from the aircraft and descends to the surface.
