Automatic Weather Stations

Automatic Weather Stations
ENTRY DATE: 03 May 2015| LAST UPDATE: 03 May 2015
Categories: Disaster Prevention | Observation systems, information dissemination
Technological Maturity: Applicable immediately, ongoing research and development 
Technology Owners:
  • Governments
  • Private companies
Needs Addressed
  • Availability of climate information at the community level
  • Better linkages for facilitating response process
  • Better linkages of supplier of climate information
Adaptation Effects
  • Increase the number and reliability of surface observations of weather
  • Indicate the onset of climate related disaster events
  • Information can be directly transferred onto an accessible system that communicates weather changes to communities, enabling their response 
Overview and Features

Outdoor weather sensors measure weather elements such as air temperature, humidity, wind direction, wind speed, air pressure, and rainfall.  These sensors can transmit recordings automatically to a central indoor computer, which stores and shares the data. Data measurements are made at predetermined intervals as necessitated by the user requirements. Data can be recorded on site or be transmitted in real-time.

  • Capital costs for automated weather stations, new modems, computer platforms and software to access and display precipitation data from radar, a dedicated forecaster workstation system, and training staff at forecast centres are estimated at USD 18,477 per automated station (World Bank, 2013)
  • Annual costs for annual support for the dedicated forecaster workstation are estimated at USD 1,339 per automated station (World Bank, 2013)
  • In Cambodia, the estimated costs for installing 24 Automatic Weather Stations (AWS) and providing the necessary training were estimated at USD 6,309,590 (UNISDR,
  • Communication costs can be reduced by basing data collected from the Automatic Weather Stations on a GPRS system 
Energy Source

Electricity for operation of the equipment

Ease of Maintenance
  • Ongoing, routine maintenance required, which can be costly.
  • It should include maintenance of equipment and training for technicians, specialists and operators as well as   information users 
Technology Performance
  • The area representation is limited to around 3-5 km per station
  • These systems have been proven to provide more accurate, beneficial and round-the-clock data than previous forecasting systems which can enable better disaster preparedness
  • Enables data collection in harsh climates
  • Well suited for use in remote places without electricity
Considerations (technology transfer criteria, challenges, etc.)
  • Knowledge and funds needed for installation
  • Sensors must be installed at the appropriate location to gather the data required
  • Consideration should be made as to the type of data required 
Co-benefits, Suitability for Developing Countries
  • Collates and archives a history of valuable meteorological information
  • Could be operated at the community level provided proper training is given
  • Sufficient and ongoing funding is required
