Title: Climate data for saddle data loggers (CR23X and CR1000), 2009 - 2021, hourly.
Climatological data were collected from the saddle climate station on Niwot Ridge (3525 m elevation) throughout the year. From 2000-06-24 to 2012-03-24, data were recorded using a Campbell Instruments CR23X data logger. Subsequently, data were recorded using a Campbell Instruments CR1000 data logger. This data set includes data beginning in 2009. Maximum and minimum values were recorded instantaneously, with a sampling interval of 5 seconds. Hourly means and totals were calculated from 720 individual measurements. The CR23X logger was programmed to generate both hourly and daily output. The CR1000 logger generated daily, hourly, and minute data until September 2014, and 10 minute and minute data thereafter. This dataset discontinued, see methods for instructions on accessing the 10 minute data instead.  more » « less

From 2000-06-24 to 2012-03-24, 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 were recorded instantaneously, with a sampling interval of 5 seconds. Daily means and totals were calculated from 17,280 individual measurements. The CR23X logger was programmed to generate both hourly and daily output. The CR1000 logger generated daily, hourly, and minute data until September 2014, and 10 minute and minute data thereafter.

  2. Climatological data were collected from the C1 climate station on Niwot Ridge (3018 m elevation) throughout the year. From 2000-06-24 to 2013-03-25, data were recorded using a Campbell Instruments CR23X data logger. Starting 2013-03-27, data were recorded using a Campbell Instruments CR1000 data logger. Maximum and minimum values were recorded instantaneously, with a sampling interval of 5 seconds. Daily means and totals were calculated from 17,280 individual measurements. The CR23X logger was programmed to generate both hourly and daily output. The CR1000 logger generated daily, hourly, and minute data until 2014-09-10, when these time periods were discontinued and only 10 minute raw data were collected.

  3. 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).

  4. Climatological data are collected from the D1 climate station on Niwot Ridge (3738 m elevation) throughout the year. Data were recorded using a Campbell Instruments CR1000 data logger. Maximum and minimum values are recorded instantaneously, with a sampling interval of 5 seconds and programmed to generate 10 minute output. These data represent the native resolution (10 minute) data from 2014 onward, with quality flags applied but no data removed.

  5. Climatological data were collected from the saddle climate station on Niwot Ridge (3525 m elevation) throughout the year. Data were recorded using a Campbell Instruments CR1000 data logger. Maximum and minimum values are recorded instantaneously, with a sampling interval of 5 seconds. This instrument was programmed to generate 10 minute output starting in September 2014. These data represent the native (10-minute) resolution data from that point from onward, with quality flags applied but no data removed.
