OMPS (Ozone Mapper Product Suite) is a three-part instrument: a nadir mapper that maps global ozone with about 50-km ground-resolution, a nadir profiler that measures the vertical distribution of ozone in the stratosphere, and a limb profiler that measures ozone in the lower stratosphere and troposphere with high vertical resolution.
OMPS, an advanced suite of two hyper spectral instruments, extends the 25-plus year total-ozone and ozone-profile records. These records are used by ozone-assessment researchers and policy makers to track the health of the ozone layer. The improved vertical resolution of OMPS data products allows for better testing and monitoring of the complex chemistry involved in ozone destruction near the troposphere. OMPS products, when combined with cloud predictions, also help produce better ultraviolet index forecasts.
OMPS measures the global distribution of the total atmospheric ozone column on a daily basis. It also measures the vertical distribution of ozone from about 15 km to 60 km, though somewhat less frequently. Ozone is an important molecule in the atmosphere because it partially blocks harmful ultra-violet light from the sun. The Nadir instrument looks directly below the satellite while the Limb instrument looks at an angle to the Earth's surface. Combining the two views will enhance the ability of scientists to measure the vertical structure of ozone, which is important in understanding the chemistry of how ozone interacts with other gases in the atmosphere. The third portion of the suite is the Main Electronics Box (MEB), which controls the operation of the instruments and then captures and routes the data to the spacecraft. The NPP OMPS instrument contains both the Nadir and Limb sensor while JPSS-1 is flying only the Nadir sensor. OMPS carries on a long tradition of space borne measurements of ozone beginning in 1970 with the Nimbus 4 satellite and continuing with the Solar Backscatter Ultraviolet (SBUV and SBUV/2) and Total Ozone Mapping Spectrometer (TOMS) instruments on various NASA, NOAA, and international satellites. The instruments measure ozone by collecting light from the sun that has been reflected off of the atmosphere. Ozone molecules absorb some of this light and these absorption features are used to calculate the amount of ozone present over the entire globe.

All OMPS products are available in orbital form (from the Ozone Mapper Product Suite - OMPS) for near-realtime users. To receive near-realtime products contact the Ozone Product Area Lead or the ESPC Operations Help Desk.
The products in netcdf format are archived at CLASS, accumulated in monthly datasets available within 3 days after each new
month.
