TMY generator

A typical meteorological year (TMY) is a set of meteorological data with data values for every hour in a year for a given geographical location. The data are selected from hourly data in a longer time period (normally 10 years or more). The TMY is generated in PVGIS following the procedure described in ISO 15927-4.

The TMY tool can be used to interactively visualise all the data or to download it as a text file. 

The solar radiation database (DB) used is the default DB for the given location, either PVGIS-SARAH, PVGIS-NSRDB or PVGIS-ERA5. The other meteorological variables are obtained from the ERA-Interim reanalysis.

The tool can be accessed with:
