Bonanza Creek Experimental Forest Precipitation (Water Buckets/Rain Gauges) at BCEF LTER sites: Weekly

Three (in clearings) or four (under canopies) Weather Bureau standard rain gauges have been placed on stands at a height of approximately 1 m at each site with meteorological measurements. Rainfall is measured each week during the summer with a dip stick. Measurements are entered into the computer and averaged by site and date. Prior to 1991 measurements were in inches. These data have been converted to mm.每个气象观测站点均以高度约1米的支架安置雨量筒：开阔空地处设置3个，林冠下方设置4个，均为美国气象局标准雨量筒。夏季期间，每周使用量雨杆测量降雨量。观测数据录入计算机后，将按站点与日期求取平均值。1991年之前的观测单位为英寸，现已全部转换为毫米（mm）。
