Humidity Data Access and Tools

NASA’s humidity data range from hourly primary forcing data to modeled data based on measurements from high-altitude aircraft. Our datasets and tools help users find and integrate the data they need to see how humidity influences weather, ecosystems, and how we live our lives.

Featured Humidity Observation Method: MLS

The Microwave Limb Sounder (MLS) instrument is carried aboard the Aqua satellite and acquires measurements globally day and night. The MLS makes measurements of atmospheric composition, temperature, humidity and cloud ice that are needed to learn more about weather, climate, and air quality.

MLS Near Real-Time Data

Near real-time atmosphere, temperature, humidity, and cloud ice data from the Microwave Limb Sounder (MLS) are available through NASA's Land, Atmosphere Near real-time Capability for Earth observation (LANCE).
