1 GOES R Introduction and Overview: The Requirements Process
Satellite Direct Readout Conference for the Americas Miami, FL December 12, 2002

2 Integrated Approach to Observations
User Needs Other Data Polar POES (Today) w/METOP (2005) NPOESS (2009) Geostationary GOES I-Series (Today) GOES N-Series (2004) GOES R-Series (2012) Other Satellites NASA DoD International Commercial

3 GOES Launch Planning Availability Planning Launch Satellite Date Date
GOES N Jan 2004 Apr 2004 GOES O Apr 2005 Apr 2007 GOES P Apr 2007 Oct 2008 GOES R Apr 2012 Apr 2012 GOES S Apr 2013 Apr 2015

4 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

15 Cost and Benefit Analysis Strategy/Methodology
Focus analysis on determining Linkages from improved GOES-R sensors to economic benefits Avoidable economic losses due to improved advanced warnings of events and improved forecast accuracy Characterize information flow from sensors to "end-users” Determine impacts of the instrument improvements on our products - current emphasis on ABI/HES Identify key benefit domains Hold user forums to elicit insight into improved product benefits

16 Benefit Areas Investigated
Agriculture Reduction of temperature error Reduce unnecessary and expensive frost/freeze mitigation activities Improved soil moisture measurement accuracy Reduce over-irrigation Aviation Improve convective weather forecasts Improve route planning Reduce delays/deviations/cancellations; reduce fuel consumption Volcanic Ash Avoidance Reduce $M in damage and potential loss of lives

17 Dust Over Southwest U.S.

19 Benefit Areas Investigated
Recreational Boating Improve hurricane lead time: Reduce boat loss and damage Trucking Improve severe weather lead time / location: Reduce # of accidents/deaths Utilities (Electric, Natural Gas) Improve temperature accuracy: Improve load forecasting and reduce expensive spot purchases

20 Ongoing Benefit Areas Analysis - Not Yet Included in Report
Commercial Shipping Improve tropical cyclone track and intensity forecasts; Improve ship routing Emergency Management Increase lead time on severe weather forecasts and hazardous environmental matter; Improve planning and deployment *

21 Economic Benefits* Summary for GOES-R Series (2013-2027)
*These benefits are over and above those achieved by the current GOES baseline
