Meteonorm is a unique combination of reliable data sources and sophisticated calculation tools.
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.
New: Meteonorm 7.3 offers you access to hourly time series of irradiation and temperature anywhere on Earth!
Measured radiation data for the last 24 hours, updated every hour.
The core functionality of SolarSat is the delivery of radiation data independent of measurement instruments for any site from Europe, Middle East to India and Northern Africa (see Figure 2). The radiation is retrieved from satellite images. The temperature data is taken from weather forecasts.
Solar radiation forecast for the next 6 hours, updated every 15 minutes.
The shortest-term forecast CloudMove is based on a novel forecast concept. With the help of wind fields from weather models the currently measured cloudiness is propagated to the future to forecast the radiation.
CloudMove is updated every 15 minutes and delivers 15-minute values for the next 6 hours for any site from Europe, Middle East to India and Northern Africa. The precision (rel. RMSE) averages to about 20% (RMSE of satellite data) for the first forecast steps and goes towards the precision of a standard forecast within the forecast time domain of 6 hours.
Solar radiation forecast for the next 72 hours, updated every hour.
The SolarForecast is based on the global weather forecasting model GFS4 (Global Forecast System). The output of the GFS forecast model is then statistically optimised using measurement data from weather stations. This system allows for the production of an irradiation forecast with high accuracy specifically for your site.
