在过去的半个世纪里，灌溉农业得到了广泛的发展。由于灌溉的增加和由此产生的土地利用-土地覆盖的变化，美国中部在20世纪下半叶出现了气温下降和降水变化。为了调查在生长季开始时广泛开始灌溉并在整个夏季持续灌溉对当地和地区天气的影响，于2018年春夏在内布拉斯加州东南部进行了大平原灌溉实验(GRAINEX)。GRAINEX包括两个15天的密集观察期。来自多个机构和大学的观测平台被部署来调查灌溉对地表水分含量、热通量、日边界层演变和当地降水的作用。本文概述了所收集的数据，并分析了灌溉在从季节到全天的时间尺度上对陆地-大气相互作用的作用。分析表明，在7月中旬的生长旺季，灌溉信号明显。本文研究了灌溉对地表通量、近地表温湿度以及边界层增长和衰减的强烈影响。
Extensive expansion in irrigated agriculture has taken place over the last half century. Due to increased irrigation and resultant land-use–land-cover change, the central United States has seen a decrease in temperature and changes in precipitation during the second half of the twentieth century. To investigate the impacts of widespread commencement of irrigation at the beginning of the growing season and continued irrigation throughout the summer on local and regional weather, the Great Plains Irrigation Experiment (GRAINEX) was conducted in the spring and summer of 2018 in southeastern Nebraska. GRAINEX consisted of two 15-day intensive observation periods. Observational platforms from multiple agencies and universities were deployed to investigate the role of irrigation in surface moisture content, heat fluxes, diurnal boundary layer evolution, and local precipitation. This article provides an overview of the data collected and an analysis of the role of irrigation in land–atmosphere interactions on time scales from the seasonal to the diurnal. The analysis shows that a clear irrigation signal was apparent during the peak growing season in mid-July. This paper shows the strong impact of irrigation on surface fluxes, near-surface temperature and humidity, and boundary layer growth and decay.
