Meteonorm

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. Includes new aerosol/turbidity data, new minute-model data and urban heat island effect.

New features in Version 8

• More recent data from the following periods:

• 1996 – 2015: new main period for radiation parameters

• 2000 – 2019: new main period for temperature, dew point temperature, wind, precipitation and days with precipitation

These more recent time periods are denoted in the new Version as “contemporary”. It is still possible to choose a “historic” data period (1981 – 1990 for radiation and 1961 – 1990 for temperature).

• Access to ongoing current time series based on satellite (Europe, Africa, Near East) and Re-Analysis data (ERA-5T, rest of the world)

• New satellite data based on an own, globally homogeneous satellite model, including satellite data for Asia and the Americas

• Future data for IPCC Scenarios RCP 2.4, 4.5 and 8.5 from 10 global climate models based on CMIP5 are included (2020 - 2100)

• Detailed model for urban effects based on the H2020 climate-fit.city project. 100 cities in Europe include urban effects for the contemporary climates. Barcelona, Berlin, Bern, Bremen, Prague, Rome and Vienna additionally include urban effects of 2050 for two scenarios.

• Current data (downloaded timeseries) include the new parameters Td, FF, DD and RR (previously only Ta and Gh)

• The software was partly refactored, updated and bugs fixed. Climate data are mostly stored as .png files to achieve maximum compression rates.

• Clearer structure and separation of climate and/or imported / current data

• The global radiation maps have been updated. They are now based to a greater extent on satellite data.

Meteonorm 8 allows access to historical time series of irradiation and temperature after an optional in-program payment. The new archive contains hourly data since 2010 and is constantly updated. Also the new archive contains hourly data since 2010 and is constantly updated. You can download these time series directly from the Meteonorm software. Also there are enhanced urban city effect models based on H2020 project climate-fit.city

What does Meteonorm do?

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.

Meteonorm now offers access to all relevant meteorological information required for planning of solar applications through the same software platform:

  • typical years
  • monthly averages
  • hourly time series
  • Interpolation

    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.

    Data import

    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.

    Horizon

    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. Images taken with the Horicatcher can be imported and processed directly inside Meteonorm. The horizon pictures can be used to determine easily the areas where glare effects exist.

    Calculation of hourly and minute values

    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:

    • Global, direct and diffuse irradiation on horizontal and inclined surface
    • Temperature
    • Relative humidity
    • Wind speed
    • Cloud cover
    • Illuminance
    • UVA/UV radiation
    • Mixing ratio
    • Snow depth
    • Atmospheric pressure
    • Precipitation
    • Days with precipitation
    • Sunshine duration
    • Dew point temperature
    • Wet bulb temperature
    • Surface temperature
    • Linke turbidity factor




    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.

    Data export

    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.

    Meteonorm data can be exported and used in PV*SOL and T*SOL software for the most precise solar energy analysis.
