Aquarius Ancillary Data

• Ancillary data types and sources were extracted from the Level 3 Science Algorithm Requirements.

• Today’s objectives are to:– Agree that the list is complete and that the precedence of the

sources is correct.– Consider any preprocessing required (e.g., reformatting).– Plan to acquire static data sets and begin routine acquisition of

dynamic data sets.
