Scheduled for launch in October 2011, the NPOESS Preparatory Project (NPP) mission includes the Ozone Mapping and Profiler Suite (OMPS) which is composed of two Nadir looking sensors and an Earth-limb viewing sensor. This paper is concerned with the OMPS limb sensor, the primary product of which is an ozone vertical profile with a 1.5 km vertical resolution, a vertical range of cloud top to 60 km and an along-track spacing of 125 km. Secondary products include stratospheric aerosol vertical distribution, cloud top height and NO2vertical profiles. The paper describes the OMPS mission (sensor specifications, orbital characteristics, timeline), reviews the heritage in space-based ozone measurements, illustrates the limb sensor expected performance (accuracy and precision), describes the planned product validation effort (comparison with ground and space instruments) and defines the data release procedure (content, format and release schedule). |
