Meteonorm 7.3 allows access to historical time series of irradiation and temperature. The new archive contains hourly data since 2010 and is constantly updated. You can download these time series directly from the Meteonorm software.
Thanks to this new feature, Meteonorm now offers access to all relevant meteorological information required for planning of solar applications through the same software platform:
To get access to the data archive, you need a registered license of Meteonorm 7.3. The upgrade from Meteonorm 7.2 to 7.3 is free.
Depending on your needs you can chose from three different packages. One single request corresponds to one year of hourly values for one site:
Irradiation data for Europe, Middle East and Africa is derived from Meteosat Second Generation (MSG) satellite data. Irradiation data outside this area is taken from ERA5 reanalysis data. Temperature profiles are modelled with measured Tmin and Tmax daily data. This allows better reproduction of the daily cycles of the temperature than with ERA5 data.
The irradiation dataset was compiled combining the Heliosat method applied to the visible channels 1 and 12 (High Resolution Visible) with a multichannel retrieval for snow cover detection using near infrared and infrared channels. A statistical regression approach integrating ground measurements is adopted for bias correction and uncertainty reduction.
In Meteonorm 7.3, there is a new button "Daily/hourly values" in the menu "modification & data import". Via this button, you get to a new screen in which you can download hourly values for the selected site and year. The data will be saved in a specific folder so that you can access the data anytime.
In this window, the current number of available single requests is displayed. You can buy a new package online dierctly from this window.
One request contains: Hourly values of one year.
This new offer can be combined with all benefits of Meteonorm:
We plan to extend the time series service in the future with more meteorological data from the ERA5 reanalysis. At the same time, we plan to include irradiation data from other satellites to extend the availability to America, India and Asia.
