AB: Measurements from the original TOMS and SBUV instruments onboard the Nimbus-7 spacecraft form one of the cornerstones of satellite-based studies of long-term ozone trends. These sensors established the use of the backscattered ultraviolet (BUV) technique, along with calibration techniques based on the measurement of solar flux, to determine and monitor total column and profile ozone amounts on a global, daily basis. They also provided the foundation for the design and development of the Meteor-3, ADEOS, and Earth Probe TOMS sensors and NOAA's successful SBUV/2 series of ozone sensors, whose total column and profile ozone measurements continue through today to extend the set of ozone measurements begun by Nimbus-7. The Ozone Mapping and Profiler Suite (OMPS) is a new generation of hyperspectral BUV sensors that are currently in development for the National Polar-orbiting Operational Environmental Satellite System (NPOESS). These sensors, whose first launch will be onboard the NPOESS Preparatory Project (NPP) satellite in 2006, are designed to continue this long-term data set with better accuracy, precision, and other requirements than any of the total column and profile ozone retrieval systems currently in orbit. In developing the OMPS suite to meet the NPOESS requirements, we systematically analyzed the performance of current BUV systems. We determined that the TOMS sensor and algorithm provided a strong starting point for the development of the OMPS total column ozone retrieval system and we identified areas where design improvements in both would lead to the performance necessary to meet the NPOESS requirements. Since we also determined that an SBUV-type nadir-looking sensor would not meet the NPOESS profile ozone requirements, the OMPS system includes both a nadir profiling sensor to provide measurements that directly link to the SBUV and SBUV/2 heritage dataset and a sensor-algorithm system that uses the limb-scattered BUV/Visible technique pioneered by SOLSE/LORE, OSIRIS, and SCIAMACHY to provide ozone profile measurements within the NPOESS-required accuracy and precision. In this presentation we will provide an overview of the OMPS sensors and algorithms, both in terms of their links to the past and improvements designed to meet the performance requirements of the future.
