Launched on October 28, 2011, the Suomi National Polar-orbiting Partnership
(SNPP) is a polar orbiting operational environmental satellite system which
provides measurements of land, oceans, and the atmosphere. SNPP extends and
improves upon the Earth system data records established by previous Earth
Observation Systems (EOS). There are five instruments/sensors on board SNPP
which collect climate data to help predict long term climate change and
operational weather data to predict short term weather conditions. SNPP
provides full global coverage, twice each day with a 4 day revisit cycle.
The Ozone Mapping and Profiler Suite (OMPS) is carried on SNPP.
The Ozone Mapping and Profiler Suite (OMPS) is a hyperspectral instrument
which consists of three spectrometers designed to measure the concentration
of ozone in the Earth's atmosphere. The three spectrometers which comprise
the OMPS suite are a downward-looking nadir mapper (OMPS-NM), a nadir
profiler (OMPS-NP), and a limb profiler (OMPS-LP). OMPS builds upon the more
than 3 decades of ozone and ozone profile records established by the Solar
Backscatter Ultraviolet Radiometer (SBUV and SBUV/2) and the Total Ozone
Mapping Spectrometer (TOMS). The complete OMPS suite currently flies on
board the Suomi National Polar-orbiting Partnership (SNPP) spacecraft.
Sulfur dioxide (SO2) produced from volcanoes and anthropogenic sources is
also monitored by OMPS. OMPS provides near real-time data to detect,
monitor, and characterize SO2 and ash injected into the atmosphere from
volcanic eruptions. Sulfur dioxide and aerosol data from OMPS is used to
assess the impacts of volcanic eruptions on air traffic control operations
globally.

Launched on November 18, 2017, NOAA-20 (designated Joint Polar Satellite System (JPSS-1) before launch) joined
the SNPP satellite in the same orbit. NOAA-20 extends and improves upon the Earth system data records
established by previous Earth Observation Systems (EOS). NOAA-20 is approximately 50 minutes ahead of SNPP which
helps provide observational overlap between the satellites. NOAA-20 is a polar orbiting satellite providing full
global coverage, twice each day with a 4 day revisit cycle. The same sensors are on board SNPP are located on
NOAA-20, including OMPS.
The Ozone Mapping and Profiler Suite (OMPS) is a hyperspectral instrument which consists of three spectrometers
designed to measure the concentration of ozone in the Earth's atmosphere. OMPS builds upon the more than 3
decades of ozone and ozone profile records established by the Solar Backscatter Ultraviolet Radiometer (SBUV and
SBUV/2) and the Total Ozone Mapping Spectrometer (TOMS). Similar to OMPS on SNPP, OMPS on board NOAA-20 carries
nadir mapper OMPS-NM and nadir profiler OMPS-NP, but not limb profiler OMPS-LP. OMPS NOAA-20 provides higher
resolution than OMPS SNPP.
Sulfur dioxide (SO2) produced from volcanoes and anthropogenic sources is also monitored by OMPS. OMPS provides
near real-time data to detect, monitor, and characterize SO2 and ash injected into the atmosphere from volcanic
eruptions. Data from OMPS is used to assess the impacts of volcanic eruptions on air traffic control operations
globally.
