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
