This document outlines validation plans for the Ozone Mapping and Profiler Suite (OMPS) instrument on the NPOESS Preparatory Project satellite. It discusses: 1) The calibration and validation team members and their roles in characterizing instrument performance through comparisons with other satellite and ground-based instruments from launch through long-term monitoring. 2) The schedule of major validation tasks from pre-launch testing through intensive in-orbit validation in the first two years and transition to long-term monitoring. 3) Examples of early tests and comparisons that will be done with internal instrument measurements, early solar views, and single days of Earth view data to evaluate performance.
