Toolik Moist Non-acidic Tussock Site


A Campbell CR10x data logger, in the LTER Toolik Moist Non-acidic Tussock Experimental plots (block 2), is used to monitor weather and soil temperatures.

Sensors in the control and greenhouses plots include: air temperature and relative humidity. These sensors are read every minute and averaged or totaled every hour.

Two profiles of soil temperature are measured per treatment plot with copper/constantan thermocouple wires (TC) installed at depths of 0,10, 20, and 40 cm in inter-tussock areas. The following label codes are used: CT = control, GH = greenhouses, NP = fertilized, GHF= greenhouse fertilized, plus a 1 or a 2 for the profile number. All soil sensors are read every 15 minutes and averaged every 3 hours.

Hourly, three hourly and daily summaries are in files yyDLMNTH.DAT, yyDLMNTO.DAT, and yDLMNTD.DAT respectively, where yy is the year in which the data are collected. The original data are in file yyDLMNTDAT.ZIP which is archived at The Marine Biological Lab, Woods Hole, MA.
