## Need for GOES R Advanced Instruments

**Current Imager cannot monitor developing severe local storms and still provide simultaneous global surveillance and products**
**Current Sounder cannot see CONUS and ocean area in time required**
**Imager resolution insufficient to see details of storm formation; wind accuracy too low for new model requirements**
**Vertical moisture structure inadequately measured – improvements needed for flash flood forecasts and severe weather information modeling**
**Current Imager has limited ability to monitor volcanic ash, aviation icing hazards, snow/cloud discrimination, mid-level moisture tracking**
**Current instruments technology and parts obsolescence**
