Vaisala instruments, systems and solutions are used in diverse weather related applications.
Weather forecasting
Meteorological and hydrological institutes and their meteorologists need a continuous stream of high-quality weather data in order to make daily weather forecasts. Meteorological institutes also issue weather warnings and produce other weather data for the general public and special user groups. Moreover, meteorological institutes need weather observation data to measure and explain the state of the atmosphere and climate changes. Vaisala products play a key role in the collection of data for the weather services of meteorological institutes around the world.
Aviation weather observation
Aviation organizations are governed by international regulations and recommendations, and the stringent safety standards of civil aviation also cover weather observation instrumentation. Vaisala provides aviation authorities with reliable weather observation solutions that are used to improve passenger safety and airport efficiency.
Road and rail weather observation
The flow of traffic on roads and railways affects our everyday lives, which is especially noticeable when bad weather strikes. Traffic organizations need to be prepared for changes in the weather, and this requires access to accurate weather data in order to keep roads and railways safe. Vaisala’s weather observation systems and winter maintenance consulting services allow these organizations to provide appropriate and timely maintenance. Thus, safety can be improved, cost savings achieved and the environmental impacts of winter road maintenance reduced.
Tactical weather observation
Many weather related measurements are essential in defense applications. Land, air and naval forces around the world use Vaisala’s weather observation systems for a wide range of tactical operations – in all weathers and in every climate.
Land and water resource management
Even though technology dominates our way of life in many ways, we are still dependent on natural resources. For example, the amount and variability of water resources greatly affects society. Hydrological data is broadly used in e.g. water source and flood control, as well as in related research. Vaisala supplies automatic hydrometeorology stations and networks that are used for flood and tsunami warnings and water management.
Vaisala weather stations are also used to monitor and protect forest and land resources. Anticipating and preventing the spread of forest and land fires demands accurate weather information.
Meteorological and climatological research
Climate change affects us all. Many international research programs that aim to promote environmental protection focus on the Earth’s atmosphere. The principal parameters to be measured include the composition of the atmosphere and the physics and chemistry of clouds, as well as tropical and extreme meteorological processes. Daily weather forecasts meet the needs of these research domains. The performance of the equipment and the coverage of observations have an impact on the comprehensiveness, reliability and accuracy of data obtained on the state of the environment and atmosphere.
Lightning detection
Lightning detection information is important not only to meteorological institutes offering weather services, but also to insurance companies and power utilities. Vaisala’s lightning detection networks, which have been delivered worldwide, provide valuable information on the movements of local thunderstorms and the location of lightning strikes. Insurance companies use the information when handling insurance claims. Power utilities use this information to anticipate the need for grid maintenance following lightning strikes.
Vaisala owns and operates the U.S. National Lightning Detection Network and also operates the Canadian Lightning Detection Network. Vaisala transmits the data produced by these networks to the continent’s meteorological institutes, aviation authorities, defense forces, weather service companies, insurance companies and power utilities.
