WSC - Water surface elevation (WSE) and water table depth (WTD) from 14 points at the Wibu field site, 2012-2013 growing seasons

Observation wells were installed for the purpose of continuously monitoring the water table level during the 2012 and 2013 growing seasons at the Wibu field site. These data were then used to study the yield response of corn to water table depth, soil texture, and growing season weather conditions (Zipper et al., in prep). The Wibu field site is a commercial agricultural field, which grew corn in the 2012, 2013, and 2014 growing seasons. See Zipper and Loheide (2014) Ag. For. Met. for more information about the field site. The 2012 growing season was characterized by severe drought, and the water table fell below the bottom of most wells in late June/early July.研究人员于Wibu试验场地（Wibu field site）安装观测井，用于在2012年与2013年生长季连续监测地下水位。这些监测数据随后被用于探究玉米产量对地下水位埋深、土壤质地及生长季气象条件的响应规律（Zipper等，待刊）。Wibu试验场地为商业化农田，2012、2013及2014年生长季均种植玉米。有关该试验场地的更多详情，请参阅Zipper与Loheide于2014年发表于《农业与森林气象学》（Agricultural and Forest Meteorology，缩写Ag. For. Met.）的相关研究。2012年生长季遭遇严重干旱，多数观测井的地下水位于6月末至7月初降至井底以下。
