TMY files for Norway based on CERRA data from 2006-2020

This dataset includes TMY files for all municipalities in Norway, based on CERRA data from 1991-2020, and using a TMY3 type methodology, where the FS weighing is skewed towards temperatures during the winter months (October to March).  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
• Overview of Error metrics - ZIP files containing plots of error metrics  
  • Error metrics mapped to a map of Norway, for visualization purposes
• 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. But based on the same code base as the repository TMY files for Norway based on CERRA data from 1991-2020 that was made in collaboration with The Norwegian Meteorological Office (MET).
