Raw color-of-the-ocean camera data (PACE)

PACE OCI Level-1B Science Data, version 3
ocean NASA OB_CLOUD Level 1 active netCDF-4
In plain English

What it measures. Early-stage measurements from PACE's ocean-color camera, expressed in the instrument's own calibrated units before they are turned into finished ocean or atmosphere products.

How it's made. Produced by taking the rawest PACE OCI data and processing it just one step further to put it into proper instrument units.

How & where you'd use it. A low-level building-block input that scientists feed into higher-level products; most people encounter PACE data through those finished products rather than this stage.

Official description

Level 1B (L1B) data are Level 1A (L1A) data that have been processed to instrument units (not all instruments have L1B source data).
