Meteonorm generates accurate and representative typical years for any place on earth. You can choose from more than 30 different weather parameters.
The database consists of more than 8 000 weather stations, five geostationary satellites and a globally calibrated aerosol climatology. On this basis, sophisticated interpolation models, based on more than 30 years of experience, provide results with high accuracy worldwide.
Meteonorm includes two of the best minute models on the market for reliable simulations of large PV plants or energy management & battery systems. It can model urban heat effects to support the development of green cities. It contains algorithms to calculate extreme years, for example to test design limits. You can even simulate Climate Change using IPCC scenarios.
Meteonorm is not only a desktop software: Our web service API and our Dynamic Link Library DLL ensure platform independent access to all data and models of Meteonorm, from everywhere.
You can import of any third party data, be it from satellites or from measurement stations and still profit from all tools inside Meteonorm.
The intuitive desktop software lets you to easily manage your sites and retrieve the required results in a convenient and fast way. More than 30 different output formats offer maximum flexibility.
The first version of Meteonorm was published as paperback handbook in 1985. Ten years later, Meteotest transferred the handbook to a desktop software. In 1998, the coverage of the climate data was extended from Switzerland to the whole world. The global breakthrough was reached with version 6 – back in 2007.
Today Meteonorm has more than 2 000 active users and is included in in almost every PV, solar thermal or building simulation software on the market.
All this makes Meteonorm a global standard and a powerful tool for solar energy applications, building design, heating & cooling systems, education, agriculture, forestry and many more.
Data from more than 8 000 weather stations worldwide and five geostationary satellites.
The standard periods are 1991–2010 / 1996–2015 for irradiation data and 2000–2009 for other parameters.
Current data can be downloaded inside the software. Third party data can be imported.

Meteonorm core is also available as Dynamic Link Library or Web Service.
Weather stations or satellites?
Weather stations with well-maintained good quality instruments still provide the most accurate data for solar irradiation. They represent the ground truth, which is the relevant parameter for solar energy applications. But weather stations are not always located in the vicinity of the project site and time series may be incomplete.
In this context, satellites have become a valuable source for solar irradiation data, in particular in areas with sparse distribution of met stations. However, this approach also includes disadvantages such as lack of other meteorological parameters, uncertainties in aerosol values, detection of multiple cloud layers, inaccuracies in areas with snow or no data north of 62°.
There is no standard rule which option is the best one. We always recommend combining multiple data sources of ground and satellite data to achieve the lowest uncertainty for resource assessment. Meteonorm includes weather stations and satellite data
