Combined Level 1B/ Level 2 Product Specification and Parameter Agreement

In the latest workshop, it was decided to unify Level 1B and Level 2 product specifications. This draft outlines the consolidated parameter lists from the radiometer and scatterometer teams, detailing runtime-configurable parameters output per beam and block every 1.44 seconds. All products will contain standard metadata, flags, masks, and geolocation fields. Current objectives include finalizing output parameter lists, setting target dates for Level 1A to 2 processing software integration, and gathering additional information for format specifications.

Presentation Transcript

  1. Aquarius Level-2 Product Content • As decided at the last workshop, this will actually be a combined Level 1B / Level 2 product. • The draft product specification consolidates parameter lists 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 masks and geolocation fields.

  2. Today’s Objectives • Agree (for now at least) on the list of output parameters and the list and format of the flags and masks. • Set target dates for incorporating all outputs into Level 1A-to-2 processing software • Start the process of collecting additional information (units, valid ranges) needed for the format specification.

  3. Radiometer Parameters (1 of 2)

  4. Radiometer Parameters (2 of 2)

  5. Scatterometer Parameters (1 of 2)

  6. Scatterometer Parameters (2 of 2)

  7. Ancillary Data Parameters

  8. Proposed Flags and Masks • Radiometer RFI flags to be stored in a byte array with dimensions of (blocks x beams x polarizations x subcycles) with 1 bit for each of the 5 signals in the subcycle. • Scatterometer RFI flags to be stored in a byte array with dimensions of (blocks x beams x subcycles) with 1 bit for each of the 6 signals in the subcycle. • Processing flags and masks to be stored in a byte array with dimensions of (blocks x beams) with 1 bit for each condition (e.g., land).
