Realizing the need to improve the quality and quantity of surface observations relating to weather forecasts and climate predictions in South Africa, the Currently un-sponsored the overall objective of the SAWDIS is to create a cooperative weather and disaster observer network to help the provinces and regions in South Africa to better prepare for drastic climate changes and natural disasters. Areas have been identified throughout proposed a pilot project in October 2008 that seeks to utilize the existing network of amateur radio operators and private weather stations operators to improve the reporting of meteorological observations.
While most people in industrialized countries take access to weather and disaster information for granted, in the developing world such access can make the difference between famine and feast. Moreover, for many less developed countries, most of which rely on agriculture for subsistence, meteorological and climatological information is essential for economic and social development. In the information age, it is essential that all societies the world over have equitable and timely access to information about climate change. However, one of the key challenges facing the SAWDIS is the ability to harness the power of information and communication technologies – specifically electronic media systems such as broadcasting – to disseminate relevant information to the public in remote and rural areas. The lack of a early warning system is one of the factors that is of great concern to the SAWDIS. The SAWDIS envisage to assist underdeveloped societies by means of amateur radio, commercial radio, the Internet and satellite systems in growing a vast network of grassroots weather and disaster observers. By using the Internet, Commercial Radio and Amateur Radio information can effectively be exchanged. Not only does roll players help bridge the knowledge gap between less developed regions and their more affluent counterparts, but it is also an important source for promoting improved science methodologies and interpretability of weather and disaster observations at grassroots level.
How does it work?
At the core of SAWDIS efforts to improve information and knowledge sharing between all the role players is the APRS RF and Internet Protocol-based global system. APRS consists of a combination of point-to-point, point-to-multipoint and multipoint-to-point networks that transfer weather-related information throughout the world. Connected via a comprehensive network of terrestrial and satellite links, APRS serves as the backbone of a meteorological network. At the core of the SAWDIS is the main telecommunications network, which is the global interconnection link between Internet APRS Servers, Internet IGATES, HF RF IGATES. At the local level, SAWDIS rely on amateur radio operators (HAMS) and their aperture terminals connection links to feed information into and receive critical data from the APRS/Internet Servers and HF/VHF/UHF networks
By connecting APRS Weather Services throughout the world via the Internet, APRS helps to ensure that real-time information sharing. However, many areas in
The proposal for
The urgent need exist for weather and disaster observers (amateur radio, members of the public, HAMNET) to assist the SAWDIS to render a public service. The SAWDIS is looking for weather and disaster observers in any area of the country. The SAWDIS envisage to have weather and disaster observers strategically positioned throughout the country in future to ensure the most effective distribution of meteorological and disaster information. Similar to the other projects, the SAWDIS would closely monitor the quantity and quality of the data submitted by weather and disaster observers, thus ensuring the accuracy of information.
