WeatherOnline Limited was established in 2001 and provides comprehensive weather information on its website www.weatheronline.co.uk as well as a wide range of weather related services such as XML weather data feeds and historical weather data. Personalized forecast as well as an iPhone application are available. With the new expert charts section WeatherOnline provides even specific weather information to pilots, sailors, balloonists and all other outdoor enthusiasts. Starting in 2007 WeatherOnline extended its services to the international internet user by publishing websites in several other languages such as Italian, Spanish, French, Polish, Greek and Turkish.
The WeatherOnline forecasts are created by using a MOS-System developed in-house with the most current US weather services model data (GFS). The statistical methods of the Model-Output-Statistic (MOS)- System were developed in cooperation with the Meteorological Department of the University of Bonn.
A Model-Output-Statistic (MOS)-System combines the data of the weather forecast model and the locally recorded data for any given point by transforming the model data from a coarse grid to detailed small-scale areas. In order to do so, one needs a large volume of past model forecast data as well as the corresponding recorded data for any given location. The MOS-System relates these two sets of data in an optimized fashion allowing development of the local weather forecast by using the most current model forecast.
Constant evaluation of the forecast ensures our forecasting is a dynamic process taking advantage of the newest weather data and forecast technology available.
The forecast spectrum ranges from standard meteorological parameters to special agricultural features, from sailing forecasts to skiing forecasts and from weather alerts and road conditions forecast to seasonal outlooks.
Providing uninterrupted services to its clients and the end user is paramount to WeatherOnline Ltd. along with the provision of excellent forecast services. WeatherOnline servers operate in two different locations in order to provide the most reliable services.
