Overview

Meteonorm is a comprehensive meteorological software platform that provides climatological and meteorological data for solar energy applications, building simulations and environmental research.

Meteonorm Climate synthesizes global and local meteorological data (ground-station records, satellite imagery, and climate projections) into continuous datasets. It offers two main products:

• Typical Meteorological Years (TMY): Based on climate averages from the period 2001–2020, a TMY is generated stochastically, representing a statistically typical year within the reference period. A TMY does not reflect any specific historical year but instead offers a statistically representative synthetic year for a given location. This product, called Meteonorm Climate TMY, is ideal for long-term performance modelling.
• Historic: These are observed time series derived from satellites, measurement stations and reanalysis datasets, interpolated to your location and augmented with all other available parameters in Meteonorm Climate. Historic data are available from January 1, 2010, through one month before today. This product is called Meteonorm Climate Historic and is suited for analyses requiring true past weather - not just statistical averages.

Meteonorm is a software for climatological calculations and comes in several formats: as an API, a software library (DLL), and a web application (to be released in fall 2025).

Meteonorm Climate serves as a key data source for engineering simulation tools used in photovoltaic applications passive solar design, active solar thermal systems, and building design and simulation. With its comprehensive data interfaces, it acts as a standardization tool, enabling developers and users of simulation software to access consistent and reliable meteorological data.
