ICID 1 => EARTH_GLOBAL_MIDLAT

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 moderate Earth radiances at southern and northern mid-latitudes. The dark (background) measurements of ICID 4 are eventually used to correct these light measurements in the 0-1 data processing.
