Provisional maturity, by definition, means that:

• Validation activities are ongoing and the general research community is now encouraged to participate;

• Severe algorithm anomalies are identified and under analysis. Solutions to anomalies are in development and testing.

• Incremental product improvements may still be occurring;

• Product performance has been demonstrated through analysis of a small number of independent measurements obtained from select locations, periods, and associated ground truth or field campaign efforts;

• Product analysis is sufficient to communicate product performance to users relative to expectations (Performance Baseline);

• Documentation of product performance exists that includes recommended remediation strategies for all anomalies and weaknesses. Any algorithm changes associated with severe anomalies have been documented, implemented, tested, and shared with the user community;

• Testing has been fully documented; and

• Product is ready for operational use and for use in comprehensive cal/val activities and product optimization.

Please note: Provisional users bear all responsibility for inspecting the data prior to use and for the manner in which the data are utilized.
