Abstract
The current on-orbit calibration of multispectral sensors, such as MODIS and VIIRS, is a multi-step process involving numerous sophisticated components. In this report, we calls attention to various issues that have presented challenges or caused misunderstandings that are worthy to be addressed in order to make better forward progress. Primary among the issues presented is the prevalent misunderstanding of calibration strategy, its complexity and even its fundamental premise. More specific issues include systematic radiometric drift versus error residual, impact to overall radiometric accuracy by different calibration components, the use and the interpretation of uncertainty specification and the use of different evaluation and monitoring tools. Special emphasis is made for NOAA-20 and future VIIRS and the importance of having a good handle on this collection of issues.
