GOES Data Collection System Kay Metcalf NOAA GOES

GOES Data Collection System Kay Metcalf NOAA GOES DCS Program Manager 10 March, 2011

What is GOES DCS? • Near real time relay for the collection of environmental data from > 30, 000 remote sites located throughout the Western Hemisphere • Started as an experimental system in the 1970’s • Evolved into a critical operational system used by many Federal, State , Local and international agencies • Many Emergency warning systems in the U. S. and other countries rely on GOES DCS Mar-18 NOAA GOES DCS 2

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 (NOS Tide Stations, Tsunami Warning Networks) – Some older stations still report every 3 or 4 hours • Random Reporting Mode Available – Event Driven – Emergency Use more frequent observations • Flooding event, fire breakout, earthquake, volcano eruption Mar-18 NOAA GOES DCS 3
