Extending the Long-Term PMC Record with OMPS Data

The SBUV series of instruments, although designed to measure stratospheric profile and total column ozone, have also been able to detect and characterize the global distribution of polar mesospheric clouds (PMCs) since 1978. While the last SBUV/2 instrument was launched in 2009, NASA and NOAA are continuing the long-term monitoring of stratospheric ozone with the Ozone Mapping and Profiling Suite (OMPS) series of instruments. OMPS carries two instruments that can detect PMCs. The Nadir Profiler (NP) is similar to SBUV/2 in design, with a hyperspectral CCD detector. Current operations use a 250 km x 250 km footprint, but future measurements will report 50 km x 50 km pixels within this field of view. OMPS NP measurements can be processed with the current SBUV PMC detection algorithm. Results based on 4 years of OMPS NP data from the Suomi NPP satellite will be shown. The OMPS Limb Profiler (LP) makes limb scattering measurements looking backwards along the orbit using three parallel slits. The hyperspectral data cover 290-1000 nm spectrally, and from 0 km to 85-100 km in altitude. Individual bright clouds can be detected over 15-20 degrees in latitude due to the LP viewing geometry, which offers exciting possibilities for tomographic analysis. The LP center slit measurements observe the same location as the NP measurements 7 minutes later, so that OMPS has the capability to perform “common volume” PMC analysis along every orbit. Future OMPS measurements during the next 20 years will also be discussed.
