## EMWIN – TodayDescription

**EMWIN** -- is a **service** that allows users to obtain critical weather and certain other information directly from NOAA’s National Weather Service (NWS) in near *real time*.
- Intended to be used *primarily* by emergency managers and public safety officials who need timely weather information to make critical decisions
- However, it can be accessed by anyone with proper equipment.

## EMWIN – TodayDescription cont’d

- On EMWIN - NWS makes available a 24x7 data feed of current weather warnings, watches, satellite imagery, advisories, forecasts and other products.
- NWS data feed disseminated simultaneously over the internet and via the GOES satellite broadcast
- Typical information latency:
- Alerts & warnings less than 1 minute
- Forecasts ~ 2 - 5 minutes
- Graphics & imagery ~ 10 – 15 minutes

## EMWIN – TodayFunctionality

-  Data collected from a variety of sources:
- NWS Telecommunication Gateway (RTH Washington)
- NWS Weather Wire Service (NWWS)
- FTP sites
- Internet
-   Data is collected at the EMWIN servers and :
- Prioritized into high, mid, and low priority products
-  Split into 1k packets
- Assembled into a 9.6kbs serial data stream

## EMWIN – TodayFunctionality cont’d

- The Satellite data stream is sent to NOAA Command and Data Acquisition Station (WCDAS) at Wallops, Virginia
- Up linked to NOAA satellites (GOES East and West)
- Modulation – Dual Frequency Shift Keying (DFSK)
- Speed - 9.6 kbps
- Frequency  - 1690.725 MHz
-  Approximately 80 megabytes per day
- Internet dissemination is also available using Internet unicast (“Byte Blaster”) or File Transfer Protocol techniques.

## EMWINTransition to GOES-N,O,P generation

- Changes
- Responsibilities
- Prototype receiver design
- Transition planning

## Transition to GOES-N,O,P generationChanges

- Power level of broadcast must be reduced:
- from 51 dBmi down to 44.8 dBmi
- Frequency will change to 1692.700 MHz
- Modulation will change to Offset Quadrature Phase Shift Keyed (OQPSK)
- Forward Error Correction (FEC) will be utilized to compensate for reduced power
- Data rate will increase to 19.2 kilobits per second (Kbps)

## Transition to GOES-N,O,P generationResponsibilities

- NWS & NESDIS co-operative effort for development of Transition Concept
- NESDIS had technical lead for developing hardware & software
- Proof-of-concept prototype receiver has been built and successfully bench tested
- NWS responsible for public interface and transition planning
- User-vendor conferences
- EMWIN web-site updates

## Transition to GOES-N,O,P generationPrototype Receiver Design

- Hardware
- Intermediate frequency (IF) adapter to convert radio frequency to audio frequency for sound card input.
- Software
- Demodulation and decoding accomplished by government provided software run on Windows based PC

## Transition to GOES-N,O,P generation Prototype schematic 

## Transition to GOES-N,O,P generationTransitioning Planning

- GOES – N launch
- Has been delayed;  currently scheduled for May, 2006
- Space platform checkout will take about 1 month
- Field testing of prototype receiver to be done after platform checks complete
- GOES – O launch:  Tentatively scheduled for July 2007
- User-Vendor Conference
- To be scheduled after successful receiver tests
- Looking for vendors interested in designing their own version of receiver

## Transition to GOES-N,O,P generationTransitioning Planning – cont’d

- GOES – operational
- Fuel of existing GOES constellation exhausted by 2011
- Current GOES-E may run out of fuel in 2009
- No earlier phase-out of existing GOES satellites scheduled
- Detailed transition plan will be posted on EMWIN web site as soon as available
- Check for EMWIN updates at this location:

## The Third Border Initiative (TBI)

- Disaster preparedness is a high priority for the United States.
- Main activities are sponsored by USAID’s Office of U.S. Foreign Disaster Assistance (OFDA), U.S. Southern Command and the Third Border Initiative (TBI) through the U.S. State Department.
- United States is also exploring options to use TBI funds to expand regional weather forecasting and response capabilities.
- NOAA’s TBI proposal for upgrading its "hydrometeorological" network (radar, aircraft surveillance, ocean data buoys) is multi-purpose and not just for tsunamis.

## The Third Border Initiative cont’d

- The NOAA TBI Proposal:
- Would also upgrade the telecom network dedicated to sharing information on impending events, including developing a satellite-based natural hazard information network linked to the United States.
- In connection with this aspect of the Proposal, NWS in consort with the NOAA International Affairs Office, is preparing a proposed pilot plan to demonstrate the installation of an EMWIN receiving station on a selected Caribbean island and train local meteorological specialists in its use.

## The GOES-10 Move

- NOAA plans to shift the orbit of a geostationary satellite  to improve coverage over South America
- Continent will benefit from emerging Global Earth Observation Network
- Repositioning planned for October 2006 pending the successful launch of GOES-N, NOAA's new geostationary satellite, and the continued operation of GOES-12.
- Shift will help protect lives and property in North, Central and South America by significantly improving satellite detection of natural hazards.
- Will further strengthen the WMO's World Weather Watch Global Observing System.
