Meteonorm - Version 6.1 - Global Meteorological Program
Meteonorm contains a database with climate data from 8,300 stations around the world. This includes global radiation, temperature, humidity, precipitation, days with precipitation, wind speed and direction and sunshine duration. It features a horizon database that shows local altitudes of landscape features as plotted from satellites. From simply clicking on a map, it is possible to view not only climate data but also the reduction of solar radiation caused by local topography features. This is a data source for engineering design programs such as PV*SOL and T*SOL in passive, active and photovoltaic application of solar energy. It also provides a meteorological reference for environmental research, agriculture, forestry and anyone else interested in meteorology and solar energy.
Usually, measurement data can only be used in the vicinity of a weather station. Elsewhere the data has to be interpolated between different stations. Meteonorm's sophisticated interpolation models create a reliable calculation of solar radiation, temperature and additional parameters at any site in the world. Meteonorm allows you to easily manage and select your weather stations and sites.
From monthly values (station, interpolated or imported data), Meteonorm calculates the hourly values of all parameters. The resulting time series corresponds to 'typical years' used for system design.
Additionally, the following parameters are derived:
- Solar azimuth and elevation
- Global, diffuse and beam (direct normal) radiation as well as radiation on inclined planes
- Longwave radiation
- Spectral UVA/UVB, erythemal radiation
- Precipitation, driving rain
- Humidity parameters (dewpoint, relative humidity, mixing ratio, psychrometric temperature)
- The radiation parameters are for user-chosen periods 1981-1990 and 1986-2005
The generation of humidity values is optimized to fit building and climate system simulations (including extreme hourly values). Additionally, a stochastic generation model for minute values of radiation parameters is available. The program includes an intuitive interface as well as access to climate change forecasts (3 IPCC scenarios). It is also possible to use Meteonorm to find the topographical horizon around your selected location, which can be used in shading analyses.
The program produces 36 different predefined export formats. They cover most established simulation software for solar energy applications and building design. All export formats are available for hourly as well as monthly values. Data is written to ASCII files. Alternatively, parameters and desired units can be exported in a user-defined format.
