The Ozone Mapping and Profiler Suite (OMPS) aboard the joint NASA/NOAA Suomi National Polar-orbiting Partnership (Suomi NPP) satellite tracks the health of Earth's ozone layer and measures the concentration of atmospheric ozone. OMPS consists of three spectrometers: a downward-looking Nadir Mapper, a Nadir Profiler, and a Limb Profiler. OMPS collects total column and vertical profile ozone data and continues the daily global data produced by current ozone monitoring systems—the Solar Backscatter Ultraviolet Radiometer (SBUV/2) and Total Ozone Mapping Spectrometer (TOMS)—but with higher fidelity and larger swaths. 

The first OMPS launched aboard Suomi NPP on October 28th, 2011. A second OMPS was launched on November 18, 2017 aboard the NOAA-20/JPSS-1 satellite, and began providing data in January 2018, but did not include a Limb Profiler. A third OMPS was launched on November 10, 2022 aboard the NOAA-21/JPSS-2 satellite, and began providing data in February 2023.
