ARC LTER Weather Data


Detailed weather collection at the Arctic LTER Toolik Lake site (68 degrees 38'N, 149 degrees 36'W) began in June1988.  Data collected include air temperature, wind speed and direction, relative humidity, solar radiation, precipitation, barometric pressure, soil temperatures, lake temperature, lake depth, and evaporation pan depth and pan water temperature.

In 2008 Toolik Field Station took over maintenance of the main weather station. See http://toolik.alaska.edu/edc/index.php for current weather data.

In addition to the main weather station the Arctic LTER maintains several stations that collect data on the experimental plots.

Station Descriptions and links to data:

 Toolik Field Station Met station at Toolik Field Station (68 degrees 38'N, 149 degrees 36'W) since June 1988. Data collected include: air temperature, relative humidity and wind speed, wind direction, global solar radiation, photosynthetically active radiation (PAR), barometric pressure, precipitation, soil temperatures, lake temperature, lake depth, and evaporation pan depth and pan water temperature. See Toolik Field Station EDC for details on sensors that are currently deployed and for querying historical weather data. Data are also available on this web site in a yearly format.

Toolik Moist Acidic Tussock station (68 degrees 37' 27" N, 149 degrees 36' 24"W) was added in 1990 to measure soil and air temperatures and other weather parameters in the experimental plots in moist acidic tussock tundra near Toolik Lake.

Toolik Wet Sedge  station (68 degrees 37' 57" N, 149 degrees 37' 32"W) was started in 1994, this site measures soil and air temperatures in the Inlet Wet Sedge Experimental plots (Block 1) near Toolik Lake inlet.

Toolik Moist Non-Acidic Tussock station (68 degrees 38' 7" N, 149 degrees 38' 26"W) was added in 1999 to measure soil and air temperatures in the experimental plots in non-acidic (pH ~ 5.88) moist tussock tundra.

Sagavanirtuk River station (68 degrees 46'N, 148 degrees 52'W, elevation 470 m) was first started in 1986 recording data during the summer months. In summer of 1993 the station was maintain year round. In 2009 the station was discontinued.

Other Alaska North Slope weather sites with stations near Toolik Lake include: 

Doug Kane and Larry Hinzman's North Slope Hydrology Research stations (Water and Environmental Research Center(WERC), University of Alaska Fairbanks)

Alaska Natural Resources Conservation Service's SNOTEL Sites
