These PDF files show a wind data analysis summary based on all of the data collected over the period the anemometer has been in operation.
Overall Data Analysis (All Data Collected): June 21, 2001 - March 7, 2002
Overall Data Analysis (All Data Collected):
Year One Data Analysis:
Year Two Data Analysis:
In general, adjustments for site air density, power curves, hub height projections, and estimated energy production must be performed by using the raw data provided.
The data are provided in two different file formats. The binary files contain the data as recorded from the instruments. The comma delimited files are suitable for importing into a spreadsheet such as Excel.
These files contain the data points that comprise the input to the summary data file(s) above. It is important to note that some of these data points may have been omitted from the summary data because they were determined to be in error. (A typical error occurs when an anemometer ices up.)
File Naming Convention
The data files are named using a convention to identify the site, the recording period start date, and the format of the data.
In general, the data files have names in the following format:
(/'s are separators added for clarification)
siteID is a name or serveral numbers that identify the site where the data was recorded
mm is a two-digit number indicating the month the recording period started
dd is a two-digit number indicating the day the recording period started
dataformat is a single character that will identify the data format (since the two different file types are now in separate directories, this field still exists but can be ignored)
yy is a two-digit number indicating the year the recording period started
For example, the file with the name "00001128.n01" contains data for site 0000 that was recorded beginning on November 28, 2001.
This wind data is being shared by the INL as public information collected through the Department of Energy's Wind Powering America program. No claims are made as to the complete accuracy of this information, and any misuse of this information is not the responsibility of the INL or DOE. Some of the summary reports shown on this website utilize patched or marked data (marked data is not used in calculations). The raw data files are not patched. Please contact INL (see contact information below) for more information about the anemometer sites, data, how these reports were generated or how/what/when data was patched or marked.
The wind turbine models used in the summary reports shown on this web site are only examples. Analysis can be performed using many other turbine models and sizes. There are no claims or recommendations made or inferred in these sample evaluations.
