Raw ocean-color sensor data (PACE)

PACE OCI Level-0 Raw Data, version 1
ocean NASA OB_CLOUD Level 0 active binary
In plain English

What it measures. The most basic, raw form of data from PACE's ocean-color instrument: full-resolution sensor readings with the communication clutter (sync frames, headers, duplicates) stripped out.

How it's made. Reconstructed straight from the OCI instrument aboard NASA's PACE satellite, before any science processing has been applied.

How & where you'd use it. A raw building-block input used to generate higher-level products. People studying the ocean and atmosphere use those finished products, not this raw data directly.

Official description

Level-0 data are reconstructed, unprocessed instrument and payload data at full resolution, with any and all communications artifacts (e.g., synchronization frames, communications headers, duplicate data) removed.
