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.
