Who are we?

“Just tell me where it has rained, and I will know what to do.”

- A nomad from Niger

slide4
Who are we?

The RANET program began in Africa in 1998/9, following the experience of Seasonal Outlook Forums. It was recognized that benefits from advances in science and applications could only be realized if populations outside central cities could be reached.

  • Africa: 1998/99/00 -> present
  • Pacific: 2003 -> present
  • Asia, Indian Ocean: 2005
slide5
Who are we?

RANET is a cooperative effort of various national, regional, and international partners, who seek to:

slide6
Who are we?
  • RANET is a cooperative effort of various national, regional, and international partners, who seek to:
  • Make weather and related environmental information more accessible and useful to rural and resource poor populations in order to aid day-to-day resource decisions and prepare against natural hazards.
slide7
Who are we?
  • RANET is a cooperative effort of various national, regional, and international partners, who seek to:
  • Make weather and related environmental information more accessible and useful to rural and resource poor populations in order to aid day-to-day resource decisions and prepare against natural hazards.
  • Improve the dissemination capacities of national hydro-meteorological and related national services, NGOs, and other information producers, thereby increasing the profile of and active value of these organizations to local populations.
slide8
What we do?
  • RANET INCLUDES:
    • Web and Internet
    • Community FM Radio
    • HF Radio
    • SMS (Cellular Text) Messaging
    • Other Equipment Use and Maintenance
    • RANET Community Building: Newsletters, etc
    • Web Hosting
  • Network Development and Management
    • Maintain Satellite and Associated Server Systems
    • Pilot and Training Activities
    • Test and Identify Communication Solutions

Core principles? RANET IS A CONCEPT

All activities are done in collaboration with, and with the approval of, the communities and national meteorological and associated services.

slide10
Core principles?

Core principles? RANET IS A CONCEPT

Ensuring sustainability and maintenance of systems is a priority of all RANET activities, therefore we encourage local ownership and use of communication systems for multiple purposes such as education, health campaigns, community discussions, etc.

emwin emergency manager s weather info network
The Emergency Managers Information Network is a wireless, priority-driven computer weather data broadcast system.

EMWIN provides rapid dissemination of:

Warnings < 2 minutes

Forecasts ~ 5 minutes

Graphics ~ 10 – 15 minutes

Imagery ~ 10 – 15 minutes

Other (as time permits)

EMWIN Emergency Manager’s Weather Info Network

Typical EMWIN setup - Bonriki Airport Met Office Tarawa

emwin
Data are collected from a variety of sources

NOAA NWS Gateway, Weather Wire

FTP, Internet

They are assembled at the EMWIN servers and:

Prioritized

Split into packets

Assembled into a data stream

The data stream is then sent to Wallops CDA (NESDIS) where it is:

Up-linked to satellite (GOES 10 & 12 => Worldspace ASIA-STAR)

The data stream is then available to be received by user stations
