Description

The Level 2A aerosol/cloud optical products of the Aeolus mission include:

  • Geo-located consolidated backscatter and extinction profiles,
  • Backscatter-to-extinction coefficient,
  • LIDAR ratio, scene classification,
  • Heterogeneity index
  • Attenuated backscatter signals.

Resolution -

  • Horizontal resolution of L2A optical properties at observation scale (~87 km);
  • Exceptions are group properties (horizontal accumulation of measurements from ~3 km to ~87 km) and attenuated backscatters (~3 km);

Note: the resolution of "groups" in the L2A can only go down to 5 measurements at the moment, i.e. ~15 km horizontal resolution.

This could be configured to go to 1 measurement - Vertical resolution 250-2000 m (Defined by Range Bin Settings ).
