All Niwot LTER data products (except some recent data sets for which metadata but not data are available) are released to the public and may be freely copied, distributed, edited, remixed, and built upon under the condition that you provide acknowledgement as described below.

    2. Give proper acknowledgement. Publications, models and data products that make use of these data sets must include proper acknowledgement, including citing data sets in a similar way to citing a journal article. See The following acknowledgment should accompany any publication or citation of these data: Logistical support and/or data were provided by the NSF supported Niwot Ridge Long-Term Ecological Research project and the University of Colorado Mountain Research Station

    3. Let us know how you will use the data. The data set creators and Niwot LTER would appreciate hearing of any plans to use the data set. Consider consultation or collaboration with data set creators.

    4. Although efforts have been made to ensure that these data are of the highest quality, the possibility of errors exists. Plase notify the data manager of any errors at


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.


Study site was the Saddle on Niwot Ridge. Raw data are stored on (Niwot Ridge LTER server).
