  1. ICWG and Link to Other CGMS Working Groups ICWG Rapporteur: Dong Wu 17 May 2016

  2. CREW -> ICWG • 2006 Cloud Retrieval Evaluation Workshop-1 (CREW-1), Norrköping, Sweden, (23 participants) • 2009 CREW-2 in Locarno, Switzerland, (44 participants) • 2011 CREW-3 in Madison, Wisconsin, USA, (71 participants) • 2014 CREW-4 in Grainau, Germany, (69 participants) • 2014 CREW endorsed as International Clouds Working Group (ICWG) within the Coordination Group for Meteorological Satellites (CGMS) • 2016 ICWG-1, Lille, France http://www.icare.univ-lille1.fr/crew

  3. CGMS Members The CGMS main goals are to support operational weather monitoring and forecasting as well as climate monitoring, in response to requirements formulated by WMO, its programmes and other programmes jointly supported by WMO and other international agencies. Objectives and High Level Priority Plan (HLPP): • Coordination of observing systems and protection of assets • Coordination of data access, contributions to the WMO Information System (WIS) • Enhance the quality of satellite-derived data and products • Outreach and training activities • Cross-cutting issues and new challenges 16 Members and 6 Observers http://www.cgms-info.org

  4. CGMS Working Groups Working Groups WG I: Global issues on satellite systems and telecommunication coordination WG II: Satellite data and products WG III: Operational continuity and contingency planning WG IV: Global data dissemination Space weather task team International science working groups International TOVS Working Group: ITWG International Precipitation Working Group: IPWG International Radio Occultation Working Group: IROWG International Winds Working Group: IWWG International Clouds Working Group: ICWG

  5. Cloud Connections to Other Physical Processes Cloud H2O • Cloud-precipitation (IPWG) • Cloud microphysics (thermodynamic phase, particle size, etc) • Why do clouds precip? • Coupled thermodynamics (IWWG, ITWG) • Cloud-track wind • Cloud height • Cloud top temperature • Effects on atmospheric sounding • Aerosol-cloud processes • What is a cloud? • Cloud formation • Microphysical and radiative properties • Climate change Precip Aerosol cloud lifecycle

  6. Radiance Backscatter Reflectivity Extinction Motion Clouds Water Content Optical depth Height … • Radiation • Heating • Precipitation • Water cycle • Coupling • Dynamics Climate Models & CRMs Remote Sensing Particle Size
