The Ozone Mapping and Profiler Suite (OMPS) is designed to monitor ozone from space. OMPS will make measurements used to generate estimates of total column and vertical profile ozone data. These will continue the daily global data produced by the current ozone monitoring systems, the Solar Backscatter Ultraviolet radiometer (SBUV)/2 and Total Ozone Mapping Spectrometer (TOMS), but with higher fidelity. The collection of this data contributes to fulfilling the U.S. treaty obligation to monitor the ozone depletion for the Montreal Protocol to ensure no gaps on ozone coverage. The nadir sensor uses a wide field-of-view push-broom telescope to feed two separate spectrometers. The nadir total column spectrometer (mapper) measures the scene radiance between 300 and 380 nanometers (nm) with a resolution of 1 nm sampled at 0.42 nm and a 24-hour ground revisit time. Measurements from this spectrometer are used to generate total column ozone estimates with full coverage of the sunlit Earth. The nadir profiler views a 250 km cross track swath from 250 to 310 nm with similar resolution. These measurements are used in a maximum likelihood algorithm to generate ozone vertical profile retrievals. The limb sensor measures the Earth’s limb with three vertical slits. The scattered solar radiance from ground to 80 km is measured with 1 km vertical sampling in the spectral range of 290 to 1000 nm. The three slits sample the limb at 250 km cross-track intervals to provide for better than 7-day ground revisit times. The three slits are imaged onto a single charge-coupled device (CCD) (simalr to both nadir CCD detectors). The OMPS will be part of NPOESS Prep Program (2011) and the OMPS nadir sensors will be on NPOESS C1 in 2014.
