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.
Beginning in 2014, daily values were calculated from the native
resolution data (ten minute).

全年气候数据均来自尼沃特岭（Niwot Ridge）的D1气候站。2000年7月5日至2013年10月23日期间，数据由Campbell Instruments公司的CR23X数据记录仪记录；此后，数据则通过该公司的CR1000数据记录仪采集。最大值与最小值为瞬时记录，采样间隔为5秒。日平均值及总和由17280个独立测量值计算得出。该仪器经编程可生成每小时与每日输出数据；自2009年6月25日起，亦新增10分钟间隔的输出数据。记录仪生成的每日输出数据于2014年终止，此后日值改由原生分辨率数据（十分钟间隔）计算获得。
