Soil temperatures, lake temperature, lake depth, and evaporation pan depth and pan water temperature data from Toolik Field Station, Toolik Lake, Alaska for 2005.

Abstract: 

Weather data file for Arctic Tundra LTER site at Toolik Lake. Only the sensors that are measured every 10 minutes and averaged every three hours are include, i.e. soil temperatures, lake temperature, lake depth, and evaporation pan depth and pan water temperature.

Experimental Design/Sampling Description:
Weather data at Toolik Lake has been collected by the Arctic LTER since June 1988. The station is located about 50 meters south of the lake's edge in a sedge/moss (Tomenthypnum nitens-Carex bigelowii) vegetation. Sensors that are measured every minute and averaged or totaled every hour include: air temperature and relative humidity at 1 and 5 meters, wind speed at 1 and 5 meters, wind direction at 5 meters, global solar radiation, photosynthetically active radiation, barometric pressure, and precipitation. Sensors measured every 10 minutes and averaged every three hours include: soil temperatures, lake temperature, lake depth, and evaporation pan depth and pan water temperature. Pan evaporation are only measured during the summer months. The hourly data are in the file yyyyDLTLH.DAT, the three hourly data are in yyyyDLTLO.DAT, and daily summaries are in yyyyDLTLD.DAT. A second datalogger about 700 meters from the main weather station logs air and soil temperatures and photosynthetically active radiation in the experimental treatment plots. Treatments include greenhouse, shading, and fertilization. In the control plot wind speed and direction, global solar radiation and unfrozen precipitation are also measured. This station is also used as a backup to the main weather station. The full description of the sensors and site is in file SENSORS.DOC. The original data is in file yyyyDLTDAT.ZIP which is archived at The Marine Biological Lab, Woods Hole, MA.

NOTES AND COMMENTS: Lake temperature is measured at the lake depth measurement. Soil temperatures consist of two profiles in a moss dominated plant community. They are within 3 meters of the weather station. . See additional notes under Comments variable

Data was lost during the winter of (2005-2006 31Dec05 – 20Apr06) when a storage module filled up.

Version Changes: 

Jan2007: Checked data and documentation. Data now are through end of year. Jiml
Version 2: Upadte LTERNET Data Access server proxy link for Excel and comma delimited data files. Changed from knb to das in url.
Version 3: Metadata updated to newer form (with sites sheet). CH April 2013.
Version 4 Formatted hhmm so that it includes the leading 0 JimL 21May13
Version 5: Corrected Distrubution URL. It had xlsfiles in the path. Jim L 19Jun14
Version 6: Changed Distrubution URL since the LTER network DAS system is being discontinued. JimL 9Apr2015
