Meteonorm v7.1.3
List of all Meteonorm Features
Meteonorm – what is it?
Meteonorm is a comprehensive meteorological reference. It gives you access to a catalogue of meteorological data for solar applications and system design at any desired location in the world. It is based on more than 25 years of experience in the development of meteorological databases for energy applications.
Meteonorm addresses engineers, architects, teachers, planners and anyone interested in solar energy and climatology.
Why do I need Meteonorm?
Meteonorm is considered to be the meteorological reference for the following applications: solar energy, building design, heating & cooling systems, education, renewable energy system design, agriculture and forestry, environmental research and many more!
8\’325 meteorological stations worldwide
Numerous global and regional databases have been combined and checked for their reliability. In the present version, most of the data is taken from the GEBA (Global Energy Balance Archive), from the World Meteorological Organization (WMO/OMM) Climatological Normals 1961–1990 and from the Swiss database compiled by MeteoSwiss.
The periods 1961–1990 and 2000–2009 are available for temperature, humidity, wind speed and precipitation; the periods 1981–1990 and 1991–2010 for solar radiation.
Monthly climatological (long term) means are available for the following eight parameters:
global radiation
ambient air temperature
humidity
precipitation
days with precipitation
wind speed
wind direction
sunshine duration
The station data is supplemented by surface data from five geostationary satellites. This data is available on a global grid with a horizontal resolution of 8 km (3 km in Europe and Northern Africa).
Interpolation – data for any site worldwide
Usually, measurement data can only be used in the vicinity of a weather station. Elsewhere, the data has to be interpolated between different stations. The sophisticated interpolation models inside Meteonorm allow a reliable calculation of solar radiation, temperature and additional parameters at any site in the world. The intuitive GUI in Meteonorm 7 allows you to easily manage and select your weather stations and sites.
Import current as well as your own data
Meteonorm offers dynamic web downloads of current monthly temperature and radiation data (for Europe available data from 2007 onwards). With one mouse click, current data is imported from the internet and displayed. This allows solar energy calculations and performance checks of energy systems based on current data sets.
You can import your own monthly or hourly radiation and temperature data into Meteonorm with a specific import interface. Subsequently, you can apply the Meteonorm models and procedures to this data to gene rate random time series.
Calculation of hourly and minute values
From the monthly values (station data, interpolated data or imported data), Meteonorm calculates hourly values of all parameters using a stochastic model. The resulting time series correspond 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
luminance
UVA/UVB, erythemal radiation
precipitation, driving rain
humidity parameters (dewpoint, relative humidity, mixing ratio, psychrometric temperature)
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.
Effects of high horizon considered
Meteonorm calculates reduced global radiation caused by a high horizon. The horizon line can easily be entered either graphically (drag line) or numerically. For most regions of the world, the horizon line is calculated automatically, based on a digital terrain mode (accessed over the internet).
Any rectified picture of the horizon can be imported and used as a background for digitizing the horizon. As a new feature in Meteonorm 7, images taken with the Horicatcher can be imported and processed directly inside Meteonorm. The additional Horicatcher software is not needed anymore.
