Minimize Earth Observation Mode - FR or RR TOA Radiances

This product consists of the physical measurements from the instrument. These are Top Of Atmosphere (TOA) radiances, calibrated to geophysical units (W.m-2. sr-1 ┬Ám-1), georeferenced onto the Earth's surface, spatially resampled onto an evenly spaced grid and annotated with illumination and observation geometry, environment data (meteorological data) and quality and classification flags.
The product is available at two spatial resolutions: full resolution and reduced resolution.

The OL_1_EFR product (OL_1_ERR for reduced resolution) is described in the following table.
