If you need Meteonorm datasets at specific sites only every now and then and don't want to buy a Meteonorm licence, you can buy the typical years you need.
A Meteonorm dataset contains values of the required weather parameters for a typical year in the selected time intervall (minute, 10/15-minute, hourly or daily values). The typical year corresponds to the long term mean and is therefore the reference for assessments and planning purposes.
