The OMPS Limb Profiler Environmental Data Record Algorithm Theoretical Basis Document and Expected Performance

The retrieval algorithm for the Suomi National Polar-Orbiting Partnership (NPP) Ozone Mapping and Profiler Suite (OMPS) Limb Profiler is described. The goal of the OMPS Limb Profiler is to produce high quality vertical profiles of ozone in the stratosphere and upper troposphere. Additional products include aerosol extinction vertical profiles together with an estimate of the Angstrom coefficient, cloud top height and $\hbox {NO}_{2}$ column density. The ozone retrieval algorithm relies on the optimal estimation approach, and uses the Pair/Triplet methodology. Estimates of bias and random errors are presented, together with a brief description of the operational code output products and the planned validation.
