This visualization displays the power spectrum of wind speed data from the CSAT3A 3-D Sonic Anemometer. It uses a Fast Fourier Transform (FFT) to convert a 10-minute sample of the Uy wind component into frequency-domain magnitudes, plotted as decibels against frequency in Hertz. The custom FFT implementation computes the transform, and d3’s `scaleLinear`, `line`, and axes helper functions render the resulting spectrum on a gray plot area. Data comes from the `@drbagwell/csat3-data-file` package.

AI-generated description

Overview The CSAT3A 3-D Sonic Anemometer is the 3-D sonic anemometer of choice for eddy-covariance measurements. It has an aerodynamic design, a 10 cm vertical measurement path, operates in a pulsed acoustic mode, and withstands exposure to harsh weather conditions. Three orthogonal wind components (ux, uy, uz) and the speed of sound (c) are measured and output
