GLA09 should not contain elevated aerosol layers, only cloud heights. If the GLA09 algorithm detects a layer in the data, a cloud/aerosol discrimination routine is called. If the layer is considered cloud, then it is output to GLA09. If it is aerosol, then it is output to GLA08. The only separate algorithm used in GLA08 is for PBL height retrieval.
