2. Apr-12 NOAA GOES DCS 2 What is GOES DCS? A GOES data service used for the collection of environmental data in real-time from > 30,000 remote data collection platforms located throughout the Western Hemisphere Started as an experimental system for collecting real-time data that has evolved into a critical operational system used by many Federal, State, Local and International agencies It has become the backbone of many agencies' real-time data collection programs Many Emergency warning systems in the U.S. and other countries rely on GOES DCS

3. Apr-12 NOAA GOES DCS 3 How Does it Work? Frequency Share/Time Share System 400 khz of Bandwidth Assigned to GOES DCS Divided into Approximately 200 channels of 1.5 khz Each Transmitter Assigned a Channel/Time Slot Standard Assignment is Hourly, for 10 seconds Some report more frequently (Tsunami Warning Stations) Some older stations still report every 3 or 4 hours Random Reporting Mode Available Event Driven Emergency Channel has more frequent observations Flooding event, fire breakout, earthquake, volcano eruption

7. Apr-12 NOAA GOES DCS 7 Hazard Monitoring Uses U.S. Fire Weather Remote Automated Weather Station (RAWS) Operated by USFS, BLM, state and local fire agencies Estimated 4000 stations National Standard for Fire Weather Data Available through AWIPS Available on the Internet http://fire.boi.noaa.gov http://raws.wrh.noaa.gov/rawsobs.html http://www.fs.fed.us/raws

8. Apr-12 NOAA GOES DCS 8 Hazard Monitoring Uses U.S. Flood Data USGS Stream Gauge Program Approximately 10,000 stations US Army Corps of Engineers Flood Monitoring Approximately 3,000 stations International Meteorological Services Approximately 5,000 stations Throughout North, Central and South America and the Caribbean and Pacific Islands Distributed Through the NWS HADS http://www.nws.noaa.gov/oh/hads/

9. Apr-12 NOAA GOES DCS 9 Water Applications Approximately 70% of system usage is for water applications. Flood Monitoring Dam Monitoring Reservoir Management Tide gauges Tsunami Warnings Water Quality Levee Management

10. System Improvements New Transmitters use less time and frequency High data rates already in use (300 and 1200 bps) 100 bps transmitters must be replaced by June 2013 Narrow band transmitters under development Available in 2010 Maybe software update New data processing system to replace DAPS DCS Administration and Data Delivery System (DADDS) Self register at http://dcs1.noaa.gov Internet access, browser based, 30 day archive Beginning development for two way communication Query and reprogram station remotely using GOES (in 3 to 4 years) Apr-12 NOAA GOES DCS 10
