The Best data as basis for best forecasts

weather stations across the globe

UBIMET supplies reliable and highly accurate weather forecasts and severe weather warnings in real time using its own algorithms and models. Raw weather data provides the basis for UBIMET’s models and for each forecast. UBIMET combines  data from lightning detectors, satellites, radars, weather buoys and radiosondes.

UBIMET has access to very advanced satellite, weather radar, weather buoy, radiosonde and lightning data for real-time reporting and precise analysis. As such, UBIMET has access to one of the largest and most advanced weather station networks in the world. The data is continuously updated on high-security servers and processed for regional and local forecasts.

weather station data and network

  • UBIMET’s dense weather station network provides an accurate overview of the current weather situation including all the relevant parameters including temperature, wind, humidity and hours of sunshine. This data, and measurements with high temporal resolution, are particularly essential for complex terrain (for example the Alps, low mountain ranges and coastal regions).
  • Accurate forecasts in real time: The data from the stations feed into UBIMET’s high-resolution weather models. This means that the model’s starting point is continually updated to reflect reality.
  • Through the use of stations in critical locations (e.g. mountain passes, railway lines, airfields and many more), small-scale but significant weather events can be better observed. As such, even when there are signals missing from weather models, weather can still be accurately forecasted and warnings sent out.
  • UBIMET’s dense network enables the production of reports in the event of an insurance case, or the provision of weather information over a defined period of time.

Satellite data

  • UBIMET receives real time satellite images from a worldwide satellite network providing extremely high-resolution data for all locations.
  • Data from the satellites contains images of current cloud cover for a given region. The data areas from the images evaluated by UBIMET contain additional details on cloud types, the moisture content and temperature of the atmosphere, cloud cover, potential for heavy rain and storms.
  • UBIMET has access to the most up-to-date information derived from satellite images, such as wind direction and speeds in low-pressure systems or even localisation of forest fires, resulting in improved and more accurate forecasts and severe weather warnings.
  • As satellite images enable total data coverage, they are integrated into UBIMET’s forecast models.
  • Satellite data is observed closely by UBIMET’s meteorology team.  These meteorologists can update the forecasts at any time using the satellite data, proving especially useful for short-range weather developments.

Radar data

  • UBIMET has an extensive network of radar stations which can be used to continually monitor the intensity and location of rain and snow in high resolution.
  • Our broad range of radar products enables us to provide accurate warnings about potential flooding due to heavy rain or storms. Road services are also able to receive precise information about potential problems due to snow during winter.
  • The information from the radar network is used to detect hail and severe storms. This means that UBIMET can provide storm warnings that are accurate with regard to both location and time. These warnings are sent out via text message, email and our app.
  • Radar data enables us to make better short-term estimates about the snow line. In certain cases the combination of precipitation intensities and temperatures near the ground determines if and when rain may quickly turn into heavy snowfall.

Radiosondes

  • Radiosondes (also known as weather balloons) provide the meteorologists at UBIMET with valuable information regarding temperature, humidity and wind across all layers of the atmosphere up to a height of 15 kilometres. This is key because the weather in higher levels of air significantly influences the weather on the ground. Special radiosondes supply data directly from commercial air traffic, (weather data from aeroplanes that are taking off and landing) for even more accurate forecasts and severe weather warnings.
  • The data supplied by radiosondes is generally only available at two points in the day. However, it often provides a more detailed overview of the different layers of the atmosphere than other measuring methods.
  • The data from these profiles is important for UBIMET, in instances such as forecasting thunderstorms, snow or freezing rain, leading to advance warnings being sent out.

Weather buoys

  • Weather buoys in larger sea areas provide UBIMET with important data from regions otherwise not able to provide much data. This is important for forecasting and severe weather warnings, particularly in Europe where extreme weather systems more frequently originate in the Atlantic where little data is available.
  • Weather buoys supply UBIMET around the clock with information on waves and water temperatures. In some cases they also provide information on prevailing ocean currents.
  • Wind data supplied by buoys is more accurate than that gained from ships as the buoys measure at a closer proximity to the ocean surface.

Lightning data

  • UBIMET has a dense network of antennas that measure electromagnetic pulses from lightning. The use of  this temporally and spatially high-resolution information, allows for clear lightning maps to be displayed.
  • UBIMET’s weather network registers lightning strikes on the ground as well as discharges in clouds or within a thundercloud. This enables UBIMET´s meteorological team to evaluate storm cells more accurately and put out more detailed severe weather warnings.
  • UBIMET’s lightning data enables the highly accurate statistical evaluation of the path and intensity of the thunder. This ensures that our analyses and reports on, for example, the risk of a thunderstorm in particular areas, are of a high quality.
