North Temperate Lakes LTER Soil Temperature - Woodruff Airport 2006 - current

Soil temperature data are being gathered at a site at the Noble F. Lee Municipal airport located at Woodruff, WI. Soil temperature is measured at depths of .05m, .10m and .50m at 1-minute intervals. High resolution data are collected (typically at 10 minute intervals) along with 1-hour and 24-hour averages. Daily minumum and daily maximum soil temperatures and the times these occur are reported for these same depths. Data are automatically updated into the database every six hours. Prior to August 2006, only hourly averaged data are available. Starting in 2008, soil temperatures are only available from .50m depth. Sampling Frequency: varies for instantaneous sample. averaged to hourly and daily values from one minute samples Number of sites: 1

土壤温度数据采集自位于美国威斯康星州伍德拉夫的诺布尔·F·李市政机场（Noble F. Lee Municipal airport）观测站点。该站点以1分钟为采样间隔，在0.05米、0.10米及0.50米三个深度处开展土壤温度测量。同步采集高分辨率数据（通常采样间隔为10分钟），并同步生成1小时及24小时的平均值数据；针对上述所有深度，还会报告每日最低、最高土壤温度及其对应的出现时刻。数据每6小时自动同步至数据库。2006年8月之前，仅可获取小时平均尺度的土壤温度数据；自2008年起，仅可获取0.50米深度的土壤温度数据。采样频率：瞬时采样的频率存在波动，原始1分钟采样数据可被汇总为小时及日均值。观测站点总数：1个。
