The ICON Calibration and Measurement Algorithm Document (CMAD) serves three purposes:

1. It provides an ongoing record of the mission science operations plan and instrumentation status.
2. It describes the concept for calibrating the many instruments onboard ICON, including pre- and in-flight calibrations, and details the algorithms for converting instrument signals to physical quantities, including signal estimates, error analyses, and error budgets. And,
3. It serves as a user guide for each instrument’s data products, documenting best practices for analysis and the advantages/limitations in application.
