seNorge/TNb: daily minimum temperature over Norway

seNorge_2018 is a collection of observational gridded datasets for the Norwegian mainland. This dataset contains the daily minimum temperature (TNb) fields for the 64-year time period 1957-2020. TN is the minimum temperature consistent with TM/TX (yesterday at 18 UTC / today at 18 UTC). The grid spacing is 1 km. The data sources are: the Norwegian Meteorological Institute Climate Database, the Swedish Meteorological and Hydrological Institute Open Data API, the Finnish Meteorological Institute open data API and the European Climate Assessment & Dataset (www.ecad.eu).
