Featured Atmospheric Temperature Observation Method: MLS

The Microwave Limb Sounder (MLS) is radiometer and spectrometer that measures microwave thermal emission from the edge, or "limb," of Earth’s atmosphere. The MLS can measure vertical profiles of the atmosphere including temperature. The instrument acquires data globally day and night and can do so in the presence ice clouds and aerosols that would interfere with measurements from other devices.

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.

Access MLS data from GES DISC via OPeNDAP
