The data collection comprises observational, daily, monthly and annual blended data sets with a long record (blended station data series) and also daily station data series (single station data series; not blended). A description of the blending and other metadata can be found in Appendices. All available information on station positions and relocations are included in Appendices. Other metadata as descriptions of the construction of data sets and data series behind, the introduction of the Hell- mann rain gauge, the introduction of Stevenson screens (thermometer screen), information con- cerning atmospheric pressure, additional notes on monthly values, notes on multiple regressions, new corrections etc. can also be found in Appendices. A compiled set of various metadata up to 1996, covering aspects such as station position and relocations, change of instrumentation and observation units etc., that is essential to know when homogenizing time series of climate data can be found in DMI Technical Report 03-24. This publication contains information concerning a major part of the stations included in this report.
