Historical Visitor Statistics

 

As a national user facility, ARM is required to report facility use for actual visitors and for active user research computer and Archive accounts and only unique scientific users will be counted. A scientific user is defined as a member of the scientific community and infrastructure who is using ARM Facilities or data to perform peer-reviewed science and research. For the ARM Infrastructure, this includes the scientists and engineers who are involved in the development of synthesis products, value-added products, instrument performance analysis, and uncertainty quantification. Unique scientific users are defined as a single use of an ARM Facility’s on-site assets, off-site services, or data services during the defined reporting period.

Beginning in fiscal year 2013, the approach used to count scientific users for the ARM Climate Research Facility was revised to align with other DOE Office of Science user facilities. Please contact Jimmy Voyles if there are any questions related to the information presented here about the facility statistics.

Table 2. Facility Users by Year and Site*

Table 2 follows reporting guidance provided in FY2009 for counting ARM users. At that time, the new computations were applied to previous quarterly reports and user statistics were recalculated to count only scientific users.

*Scientific user numbers appear first; total number of users appear in the parentheses.
