  1. Introduction to the Gap Analysis discussionCGMS-41, WG III July 2013 Jérôme LAFEUILLE (WMO) WMO; OBS/SAT

  2. CGMS baseline for operational/sustained missions • Advanced VIS/IR imagery ) 6 GEO locations • IR Sounding (some hyperspectral) ) 6 GEO locations • Lightning detection ) 6 GEO locations  • Space Environment Monitoring ) 6 GEO locations • ERB, UV sounding, Solar activitysome GEO locations • Multispectral VIS/IR imagery ) • IR hyper-spectral sounders ) a.m., p.m., e.m • MW sounders ) • MW imagers – some polarimetric ) • Scatterometers 2 orbital planes • Altimeter constellation am,pm +reference mission • Radio occultation (>10,000 occ./day) am, pm + constellation • Broadband Vis/IR radiometer a.m. , p.m • Narrow-band (oc colour, veg, aerolol) a.m. • High Res Vis/IR a.m. constellation • IT dual angle view imagery a.m. • Particle detection, Magnetic field a.m., p.m • Solar monitoring at least two

  3. LEO / early morning : anticipated gap after DMSP expected deployment of a FY-3 satellite LEO / p.m. orbit : risk of gap between SNPP and JPSS GEO: South America coverage after GOES-12 LEO/ERB: to be confirmed (FY3/ERM, JPSS/CERES) Atmospheric composition: limb sounding ? Radio-occultation: threats on COSMIC-2 funding (late 2015 & 2018) Other «gaps» raised by WMO Exec.Council (See WP14) GPM follow-on GEO hyperspectral sounding Space Weather Gaps with respect to the CGMS baseline

  4. Contribution of current COSMIC RO constellationbetween 1000-1800 occultations/day

  5. ~ 1,300 profiles/day 2018 6 satellites polar orbits 2016 6 satellites equatorial orbits ~ 12,000 profiles/day 5 Courtesy of UCAR

  6. To be discussed by WG III • Updating and assessing the list of main risks • Discuss actions/recommendations to mitigate the risk: • Advocacy for no-gap planning • Alternative mission planning • Improved access to or use of, existing/planned alternative sources • Communication to users • ….
