(2013) for data from 2009-2014 and Jansen et al. (2019) for data from 2015-2019. Water temperature measurements are made with intercalibrated datalogger strings at different depths in three post-glacial lakes. Data are recorded at intervals between 5 and 60 minutes. Usually 5 minute recording intervals were used in summer and 15 minute intervals in winter. Data coverage (depth, time, sampling intervals) vary over time and between the lakes. Intercalibrated HOBO V2 dataloggers are used. The upper sensors (at 0.1 to 1.0 m water depth) were typically frozen in the ice in winter. The data are provided in comma-separated values (csv) files, each covering a summer or a winter season. Column headers denote the lake and the data type (e.g. 'IH_1.0 m'): ###### Lake identifiers * Inre Harrsjön ('IH') * Mellersta Harrsjön ('MH') * Villasjön ('VS') ###### Data type identifiers * Time, UTC+2 ('_Time'), * Temperature in °C at depth below the water or ice surface ('_0.1 m') A README file and supporting site information are provided as pdf files. #### Version history ##### Version 4 Negative temperatures for the winters of 2017 and 2018 were restored (minus signs had been inadvertently stripped from the data in version 3). Date stamp formats regularized to yyyy‐mm‐dd hh:mm. File names were checked and regularized. Data are comma delimited. ##### Version 3 Data record is extended and is now available for the period from 2009-06-11 to 2019-10-09. ##### Version 2 Data record is extended and is now available for the period from 2009-06-11 to 2019-06-06. ##### Version 1 Initial release. Data for the period from 2009-06-11 to 2015-06-20.
