Climate data for D1 data loggers (CR23X and CR1000), 2000 - ongoing, daily.

Climatological data were collected from a Niwot Ridge climate station (D1) throughout the year. From July 5 2000 through October 23 2013, data were recorded using a Campbell Instruments CR23X data logger. Subsequently, data were recorded using a Campbell Instruments CR1000 data logger. Maximum and minimum values are recorded instantaneously, with a sampling interval of 5 seconds. Daily averages and totals were calculated from 17,280 individual measurements. This instrument was programmed to generate both hourly and daily output. Beginning in June 25 2009, 10 minute output was also generated. Daily output generated by the logger ended in 2014.

本数据集的气候数据全年取自尼沃特岭（Niwot Ridge）气候站（编号D1）。2000年7月5日至2013年10月23日期间，数据由坎贝尔仪器（Campbell Instruments）CR23X数据采集器记录；后续采集工作则改用坎贝尔仪器CR1000数据采集器完成。该设备以5秒为采样间隔，瞬时记录最大值与最小值。每日平均值与总量由17280条独立测量值计算得到，且预设可生成小时级与日级两类数据输出。2009年6月25日起，新增10分钟级数据输出。该采集器生成的日级数据输出功能于2014年终止。
