TMY3 files for Europe based on CERRA data from 1991-2020

This dataset includes TMY files for the 5000 largest cities and towns in the EU, based on CERRA data from 1991-2020, and using a TMY3 methodology. The files represents a statistically typical year meant for energy calculations of buildings, and are therefore not suited for evaluating extreme conditions. The repository contains: EPW-files - zipped collection of .epw-files The most common file format for climate data for energy simulations applicable to most programs Datasheets - a zip files of individual datasheets A collection of datasheets containing a comparison of TMYs with the data source as well as referance data The datasheets contain Norwegian text Error metrics - ZIP file Error metrics mapped to a map of Norway, for visualization purposes As well as the metrics that are mapped Selected years - a comma seperated file the selected typical meteorological months for each location Changelog - a txt file a overview of changes in the dataset since 1.0 The contents of the repository is produced by The Norwegian University og Life Science (NMBU), Department of Building- and Environmental Technology. The data is provided 'as is', without warranty of any kind, express or implied.
