The science team for the Microwave Limb Sounder (MLS) on NASA's Aura satellite is finalizing new “Version 6” (V6) data processing algorithms and software.
We anticipate releasing V6 MLS data in summer 2024, once its quality has been assessed and documented. Reprocessing of the entire (19-year-to-date) MLS record with the V6 software will take approximately two years,
completing in mid-2026. During that time, we will continue to process incoming MLS data with the current V5 algorithms and software, thus ensuring uninterrupted
availability of a uniform MLS dataset encompassing the full mission lifetime. However, to maximize the computing resources available for V6 reprocessing, we will cease
processing the incoming data with the older V4 algorithms and software. The last V4 data generated will be for April 30, 2024.
