2003dlwso Arctic LTER 2003: Weather data collected every 4 hours from a wet sedge site at the Arctic Tundra LTER site at Toolik Lake. GUS SHAVER JIM LAUNDRE additional investigator Weather data collected every 4 hours from a wet sedge site at the Arctic Tundra LTER site at Toolik Lake. The following parameters are measured every 3 minutes and averaged every 4 hours: control, nitrogen alone, phosphorus alone, nitrogen and phosphorus, and greenhouse experimental plots soil temperatures. weather soil temperature wet sedge tundra Acceptance and utilization of LTER data requires that: The Principal Investigator be sent a notice stating reasons for acquiring any data and a description of the publication intentions. The Principal Investigator of the data set be sent a copy of the report or manuscript prior to submission and be adequately cited in any resultant publications A copy of any resultant publications should be sent to: Principal Investigator Ecosystems Center Marine Biological Laboratory Woods Hole, MA 02543 http://ecosystems.mbl.edu/ARC/data/2003dlwso.dat University of Alaska Fairbanks Toolik Field Station, North Slope of Alaska (68 degrees 38'N, 149 degrees 36'W) -149.75 -149.0433 68.8 68.5 610 1360 meter 2003 For Archival Use: DATE RECEIVED: DATA FILE ENTERED BY: Jim Laundre DATA FILE VALIDATION: NAME: Jim Laundre DATE: Data Manager

Air temperature and relative humidity and soil temperatures were collected on the treatment plots. The treatments included: control, nitrogen alone, phosphorus alone, nitrogen plus phosphorus, shade house and greenhouse. The shade and green houses were only installed June thru August. Air temperature and relative humidity was collected every hour while soil temperatures were collected every 4 hours. Notes: Greenhouses were not covered until 4Jun98 but the sensors were up year round. The data logger stopped collecting data from Feb through May. GEO-1
