It was agreed at WGCV-44 that the Atmospheric Composition Subgroup (ACSG) will take the lead on this activity.  Plans for completing this work plan item during 2019 and work related to GHGs beyond 2019 are available in the ACSG presentation at WGCV-44 from 31 August 2018. December 2018: The ACSG Expert Meeting preparations have been ongoing since the September SIT, including preparing the list of key participants, the possible dates & venue, the tentative agenda, etc. This took longer than expected overall because of the availability of key persons, extensive discussions on co-locating the meeting with other meetings, coordination with the WGClim and AC-VC. The formal invitations will go out by the end of the week.

In conclusion;it was noted that Current cloud masking and validation is lacking objectivity and a rigorous definitions of the target. Cloud class should be uniquely defined;and consistent between algorithms? flag and validation data; Cloud/no cloud is too simplistic and more refined (at least slightly) should be used.
