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.

Microwave Limb Sounder (MLS) Near Real-Time Product remains at version 3 and the MLS Standard Product moves to version 4

The Microwave Limb Sounder Near-Real Time (MLS NRT) products are provided by the Land, Atmosphere Near-real time Capability for EOS (LANCE).

MLS Products Available in GIBS

In coordination with the Microwave Limb Sounder (MLS) team, we now have several MLS products available through the GIBS image access APIs.
