Raw ocean-color imagery from a small satellite (SeaHawk-1)

SeaHawk-1 HawkEye Level-1A Data, version 1
ocean NASA OB_CLOUD Level 1 netCDF-4
In plain English

What it measures. Raw, full-resolution ocean-color imagery straight from the instrument, time-stamped and tagged with calibration and location information but not yet processed into finished measurements.

How it's made. Captured by the HawkEye camera aboard the small SeaHawk-1 satellite, packaged at the earliest (Level-1A) stage.

How & where you'd use it. A building-block input rather than a ready-to-read map; scientists process it into higher-level ocean-color products that show things like water quality and ocean plant life.

Official description

Level 1A (L1A) data are reconstructed, unprocessed instrument data at full resolution, time-referenced, and annotated with ancillary information. This ancillary information can include radiometric and geometric calibration coefficients and georeferencing parameters (e.g., platform ephemeris).
