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).
