OMPS (Ozone Mapping and Profiler Suite)

OMPS is the Ozone Mapping and Profiler Suite flown on Suomi NPP and JPSS spacecraft for ozone mapping and profiling ^[1][2]. The suite combines a nadir mapper, a nadir profiler, and a limb profiler, although NOAA-20 carries the OMPS nadir sensor without the limb profiler ^[1][3][4]. This makes OMPS a suite-level product rather than a single uniform optical channel.

The nadir mapper covers 300 to 420 nm with about 50 km native ground sampling and a 2800 km cross-track swath ^[5]. The nadir profiler covers 250 to 310 nm with about 250 km native ground sampling ^[1]. The limb profiler covers 290 to 1000 nm and provides about 1 km vertical sampling for limb ozone profiles ^[4]. The combined suite row therefore records 250 to 1000 nm, while the nadir specification records 250 to 420 nm and the limb profile channel records 290 to 1000 nm ^[1][4].

For buyers, OMPS is relevant where operational ozone continuity, broad nadir mapping, and vertical profile information are required alongside moderate spatial sampling. Its nadir mapper supports wide-swath total-column products, the nadir profiler supports ozone profile retrievals, and the limb profiler adds vertical context where carried by the spacecraft ^[1][3]. Ball Aerospace, now part of BAE Systems, designed and built the currently on-orbit OMPS instruments ^[2]. Buyers should check the host spacecraft and product stream before assuming limb coverage, because the suite configuration varies by mission instance ^[3][4].
