Abstract. The Central Netherlands Temperature (CNT) is a monthly daily mean temperature series constructed from homogenised time series from the centre of the Netherlands. The purpose of this series is to offer a homogeneous time series representative of a larger area to study large-scale temperature changes. It will also facilitate a comparison with climate models, which resolve similar scales.

From 1906 onwards, temperature measurements in the Netherlands have been sufficiently standardised to construct a high-quality series. Long time series have been constructed by merging nearby stations, using the overlap to calibrate the differences. These long time series and a few time series of only a few decades in length, have been subjected to a homogeneity analysis in which significant breaks and artificial trends have been corrected. Many of the detected breaks correspond to changes in the observations that are documented in the station metadata.

This version of the CNT, to which we attach the version number 1.1, is constructed as the unweighted average of four stations (De Bilt, Winterswijk/Hupsel, Oudenbosch/Gilze-Rijen and Gemert/Volkel) with the stations Eindhoven and Deelen added from 1951 and 1958 respectively onwards.
