Soil temperature data from the Arctic LTER Toolik Tussock Experimental plots. In 1990 a Campbell CR21x datalogger was installed in block 2 of the Toolik LTER experimental tussock plots. The plots are located on a hillside near Toolik Lake (68 38' N, 149 36'W). Sensors were placed in a control, fertilized, greenhouse, greenhouse fertilized, shadehouse and shadehouse fertilized sites.

Campbell CR21x datalogger is used to monitor weather and soil temperatures in the LTER experimental plots. Soil thermocouples were multiplexed with a Campbell AM416 multiplexer. In the control plot sensors include: global solar radiation, photosynthetically active radiation, net radiation (Fritschen type), unfrozen precipitation and 3 meter air temperature, relative humidity, wind speed, and wind direction. In the greenhouses and shade houses plots, air temperature, relative humidity and photosynthetically active radiation were also measured during the growing season. These sensors were read every minute and averaged or totaled every hour. In each plot two strings (one in a tussock and one in a moss-dominated area) of copper/constantin thermocouple wires (TC) were installed at depths of 10, 20, and 40 cm. The following label codes were used: CT=control, GH = greenhouses, SH = shadehouses, F=fertilized, GF= greenhouse fertilized, SF = Shadehouse fertilized, with a suffix of 1 for tussock or 2 for moss bed. All measurements are in degree Celsius. All soil sensors were read every 15 minutes and averaged every 3 hours. Hourly data are in the files yyDLTUH.DAT, the three hourly data are in yyDLTUO.DAT, and daily summaries are in yyDLTUD.DAT, where yy is the year in which the data are collected. The original data is in file yyDLTDAT.ZIP which is archived at The Marine Biological Lab, Woods Hole, MA. Note: The cover on greenhouses and shadehouses are removed every fall and reinstalled every spring. . Notes: Missing days: Day 167 hour 1600 to day 172 hour 1400 (Bad connection); Day 228 hour 1100 to day 231 hour 1900; Day 313 hour 0500 to end of year (Battery volts dropped below 9.7). South and north in the variable titles refers to the north or south end placement of the green/shadehouse sensors. Sampling Description.
