Short summary

Climate normals are used as reference for climate monitoring. When calculating precipitation normals for the period 1991–2020 a homogeneous reference dataset is needed. Norway's observation network has changed drastically in the last 30 years and may have introduced non-climatic changes to the time series. Homogeneity analysis of monthly precipitation series for the period 1961–2018 was performed which produced a homogenous dataset that was used to calculate the new climate normals in Norway.
