Data Usage Summary
  • Data Use Policy

    1. Use our data freely. 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 http://www.datacite.org/whycitedata). 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 lternwt@colorado.edu.

Abstract:

Two identical 3-meter towers were installed near T-Van in 2007, and continuous meteorological and eddy covariance data are presented beginning in 2008. The sampling interval was 5 seconds for the meteorological data and 10 Hz for the eddy covariance data, and 30-minute means of all variables were calculated using a Campbell Scientific CR3000 datalogger. The 30-minute mean data were subsequently averaged to create this 24-hour mean dataset. Information about specific sensors, instrumental orientation, units, and data post-processing and infilling procedures are contained in the metadata for this file.

Location:

Eddy covariance towers were located near Tvan in alpine tundra fellfield/dry meadow vegetation. The east tower (3502 m asl) was situated 50 horizontal meters northwest of T-Van (source of 120-V AC power), and the west tower (3504 m asl) was 50 horizontal meters west of the east tower along the prevailing wind direction and a 7.8% snow-scoured slope.
