Hi, ![enter image description here](https://community.wolfram.com//c/portal/getImageAttachment?filename=6786Untitled.jpg&userId=1822915)
Now I would like to calculate the value of spectral exponent for my data in the attached notebook. Thank you for your help.
data0 = WeatherData["KDRA",
"Temperature", {{1979, 1, 1}, {2020, 12, 31}, "Day"}];
regularData =
TimeSeriesResample[data0,
ResamplingMethod -> {"Interpolation", InterpolationOrder -> 1}];
data = QuantityMagnitude[regularData["Values"]];
Periodogram[data]
