We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition.

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.
The Microwave Limb Sounder Near-Real Time (MLS NRT) products are provided by the Land, Atmosphere Near-real time Capability for EOS (LANCE).
In coordination with the Microwave Limb Sounder (MLS) team, we now have several MLS products available through the GIBS image access APIs.
Learn how to visualize Microwave Limb Sounder data through OPeNDAP.
