Who are we? “Just tell me where it has rained, and I will know what to do.” - A nomad from Niger
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
Who are we? RANET is a cooperative effort of various national, regional, and international partners, who seek to:
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.
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.
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.
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.
Core principles? Core principles? RANET IS A CONCEPT RANET also works to build upon and augment existing networks and means of communication.
A Professional Quality FM Radio Station A complete broadcast station in a suitcase Ideal for a Community FM Radio Station Readily accepts any audio source Can be solar/wind powered for remote communities Wantok Community FM Radio Station The Wantok Suitcase FM Radio Broadcast System. Hakupu Village, Niue FM station on the air… Funded by NOAA, and NZAID
Applications for the Wantok SBS-1 Low cost, low power community radio station Education and training A tool for Socio-Economic Development Ideal for Disaster Alerting and Response Gets important information to the end user Owned by the Community - for the Community Wantok Community FM Radio Station The Wantok Suitcase FM Radio Broadcast System
What is HF Email? (two way communications) Email received and sent via a HF Radio Transceiver Requires a special radio modem Modem interfaces to PC or laptop Software can interface with many applications, e.g. Outlook Express, our mSTAR automatic weather station HF Radio Email Niue HF email system, quickly installed after TC Heta Funded by Met Office, UK
Why HF Radio Email? Cost effective two-way remote communications system Easy to install and operate Some Pacific NMS already have suitable HF Radios Many staff already have HF radio experience HF Radio Email Typical HF radio Email system set-up
A Reliable Portable Internet Backup Solution (two way communications) Constellation of 66 LEO satellites Small Cellular phone type handset - SMS capable Can access Iridium Direct Internet Gateway Built in Modem Rugged external marine antenna All weather capability Can use any Internet Email or Browser Client Commercial satellite - Iridium Niue Iridium Backup Coms System – installed April 2005
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
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 From here EMWIN products FM Radio, HF Email Commercial satellite EMWIN EMWIN C-Band Dish Antenna at Met Office, Port Vila, Vanuatu
