Calibration/Validation
3Joint Polar Satellite System
• Four Phases of Cal/Val:1. Pre-Launch; all time prior to launch – Algorithm verification, sensor testing, and
validation preparation2. Early Orbit Check-out (first 30-90 days) – System Calibration & Characterization3. Intensive Cal/Val (ICV); extending to approximately 24 months post-launch – xDR
Validation4. Long-Term Monitoring (LTM); through life of sensors
• For each phase:– Exit Criteria established– Activities summarized– Products mature through phases independently

EDR Status(Calibration/Validation)
• Multiple levels of maturity- Beta – products are minimally validated; available to users to verify
formats and parameters- Provisional – product quality may not be optimal; ready for
operational evaluation- Validated – product performance is well for three different stages;
ready for operational use• Stage 1 - Product performance has been demonstrated to comply with the specification using a small
number of independent measurements obtained from selected locations, periods, and associated ground-truth/field program efforts.
• Stage 2 - Product performance has been demonstrated to comply with the specification over a widely distributed set of locations and periods via several ground-truth and validation efforts.
• Stage 3 –Product performance has been demonstrated to comply with the specification and the uncertainties in the product well established via independent measurements in a systematic and statistically robust way representing global conditions.
