ICID 2 => EARTH_GLOBAL_ARCTIC

Illumination:

  • Earth radiance.

Purpose:

  • Global Earth radiance measurements.

Location:

  • Dayside of the orbit (2 blocks per orbit).

Usage:

  • From launch onwards, almost every orbit, except during spatial zoom-in measurement days and during Monthly 3 observational scenario (1 orbit per month).

Description:

Earth global measurement with instrument settings optimised for low Earth radiances at southern and northern (ant)arctic latitudes. The dark (background) measurements of ICID 5 are eventually used to correct these light measurements in the 0-1 data processing.
