## GOES Program Overview

*GOES - DCS LATIN AMERICAN USER’S CONFERENCE  DECEMBER 2001*

**GOES Program Overview**

- GOES satisfies requirements for 24-hour observation of weather and Earth’s environment to support storm-scale weather forecasting by forecasters and numerical models.  To meet requirements, GOES continuously maintains operational satellites at two locations (75 degrees West and 135 degrees West), with an on-orbit spare in case of failure

- On-Orbit Storage

- Operational Spacecraft

## WEFAX

*GOES - DCS LATIN AMERICAN USER’S CONFERENCE  DECEMBER 2001*

- Manage & operate system
- Worldwide imagery and weather charts
- Low-cost easy access
- Diverse customer base
- GOES schedules
- Operational reliability critical

## Satellite-derived winds

*GOES - DCS LATIN AMERICAN USER’S CONFERENCE  DECEMBER 2001*

- Satellite-derived winds will be improved with the ABI due to:
- 	- higher spatial resolution (better edge detection)
- 	- more frequent images (offers different time intervals)
- 	- better cloud height detection (with multiple bands)
- 	- new bands may allow new wind products (1.38 m?)
- 	- better NEdT’s
- 	- better navigation/registration

## WEFAX to LRIT Transition

*GOES - DCS LATIN AMERICAN USER’S CONFERENCE  DECEMBER 2001*

- _Late 2002-Early 2003_	alternating WEFAX / LRIT transmissions	begin GOES-East
- _Early 2004_	All WEFAX ends. Only LRIT available	GOES-East & GOES-West
- _Users will require new hardware and software_

## GOES Analog WEFAX - Digital LRIT Transition

- 2001     2002       2003      2004        2005                                                                 2010

- GOES-East begins LRIT. _Alternate_: GOES-Central for LRIT only

- LRIT testing on GOES-11, -12

- GOES-N operational. WEFAX services ends, LRIT on GOES-East, -West

## Emergency Manager’s Weather Information Network (EMWIN)

*GOES - DCS LATIN AMERICAN USER’S CONFERENCE  DECEMBER 2001*

- Near real-time NWS forecasts, warnings
- Primarily for emergency managers/officials
- Transmitted at 1690.725 MHz and translated to a radio signal at 137.225MHz
- Information also available on Internet

## EMWIN DIGITAL

*GOES - DCS LATIN AMERICAN USER’S CONFERENCE  DECEMBER 2001*

- High speed digital broadcast (64-128Kbps)
- Starts in 2003
- Provides more live data and in very near real-time, plus better imagery/graphics
- Third GOES satellite may be used for transition
