Microwave Limb Sounder
Welcome
The Microwave Limb Sounder (MLS) experiments measure naturally-occurring microwave thermal emission from the limb (edge) of Earth's atmosphere to remotely sense vertical profiles of atmospheric gases, temperature, pressure, and cloud ice. The overall objective of these experiments is to provide information that will help improve our understanding of Earth's atmosphere and global change.

MLS v5 Data Release
The Aura Microwave Limb Sounder (MLS) team is pleased to announce the release of a new "version 5" MLS dataset.
Reprocessing of the entire 15+ year MLS record with the v5 algorithms is expected to complete in mid-to-late 2021. Until that reprocessing is complete, incoming MLS data will continue to be processed using older v4 algorithms as well as v5, in order to facilitate scientific analyses using a continuous dataset.
A preliminary assessment of the MLS v5 data quality, along with guidelines for appropriate use of the data, is given in the data quality document. Updates to this document are planned in the coming months, when more v5 data will be available for characterization and re-validation and updated estimates of systematic uncertainty are completed.
Data, available from the GES-DISC, can be found through NASA's Earth Data Search tool.
