  1. March 9-11, 2010 Santa Rosa, CA Aquarius Algorithm Workshop Aquarius Level-2 Data Products Fred Patt

  2. Level-2 Product Overview • Level-2 data consists of retrieved geophysical parameters at the sensor resolution, with geolocation fields appended.. • Each Aquarius Level-2 file contains 1 orbit (starting at the South Pole crossing). • Aquarius products are formatted using HDF5: • Machine-independent, hierarchical, self describing format • Attributes contain descriptive information about the entire file or individual objects within the file • Groups provide logical association and hierarchy • Data objects are multidimensional arrays of standards types

  3. Aquarius Level-2 Product Content • This will actually be a combined Level 1B / Level 2, radiometer/scatterometer product. • The current product specification incorporates updated parameter lists based on the recent code deliveries from the radiometer and scatterometer teams. • Specific parameters to be output are configurable at runtime. • Parameters are output per beam and block (1.44 sec) • All output products include standard metadata, flags and geolocation fields.

  4. Today’s Objectives • Review and agree on the list of output parameters to be used for the initial year (2007) of simulated data products, and the mission simulation. It is understood that this will continue to evolve between now and launch. • Set target dates and agree on responsibilities for incorporating all outputs into the Level 1A-to-2 processing software.

  13. Data Quality Flags • Processing flags to be stored in byte arrays with dimensions of (blocks x beams) with bits set for each condition (e.g., land). • RFI flags to be stored in byte arrays with 1 bit for each of the signals in the subcycle.
