ICID 7 => EARTH_GLOBAL_OZONEHOLE

Illumination:

  • Earth radiance.

Purpose:

  • Global Earth radiance measurements.

Location:

  • Dayside of the orbit (1 block per orbit) near south pole.

Usage:

  • From launch onwards during ozone hole conditions (September - November). When used, then 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 Earth radiances under ozone hole conditions, i.e. higher radiance levels below 310 nm. The dark (background) measurements of ICID 6 are eventually used to correct these light measurements in the 0-1 data processing. ICID 7 has sofar only been used during the ozone hole of 2004, after 18 November 2004 (orbit number 1845) ICID 7 has not been used.
