Description:
Ozone Mapping and Profiler Suite (OMPS) measures the concentration of ozone in the atmosphere, providing information on how ozone concentration varies with altitude. Data from OMPS continues three decades of climate measurements of this important parameter used in global climate models. The OMPS measurements also fulfill the U.S. treaty obligation to monitor global ozone concentrations with no gaps in coverage.
OMPS consists of three spectrometers:
- Nadir Total Column Spectrometer Provides Total Column ozone data with 50x50 km resolution at nadir
- Nadir Profile Spectrometer provides ozone profiles in a single ground pixel of 250x250 km at nadir from SNPP; 5 ground pixel of 50x50 km at nadir from JPSS-1
- Limb Sensor provides 1 km vertical sampling along three slits enabling ozone profile retrieval (Not on J1)
Heritage:
- TOMS (Nadir Total Column) and SBUV/2 (Nadir Profiler)
