Sodar - Brady, TX - Processed Data

Overview

This dataset was produced from the raw sodar .txt files from the Brady, TX site during the WFIP1 campaign. Quality control and formatting have been applied to transform the numerous raw files into a single file to provide user friendliness and improved wind resource characterization at this location.

Data Details

Location: 31.17506, -99.32607

Elevation: 548 m

Output heights: Every 10 meters from 30 meters to 200 meters

Data Quality

Data from the raw files were filtered according to the following automated and manual procedures. Missing and rejected values were flagged as -999. High precipitation events as suggested by the vertical velocity values were subjected to quality control. If any vertical velocity value at any height for a given timestamp fell below a -1.5 m/s threshold, all variables at all heights at that timestamp were rejected. On a height-by-height basis, if the signal-to- noise ratio (SNR) for any of the u, v, or w wind components reached 10 or below, all variables for that height and timestamp were rejected. The raw files were also screened for nonphysical values such as wind speeds less than zero and directions outside 0-360 degrees. Finally, the data were visually examined for events of atypical sodar retrievals, such as excessive magnitudes in oscillations or periods of stagnancy.
