Guest Post by Willis Eschenbach I’ve been investigating the use of the “complete ensemble empirical mode decomposition” (CEEMD) analysis method, which I discussed in a previous post entitled Noise-Assisted Data Analysis. One of the big insights leading to modern signal analysis was the brilliant idea of Joseph Fourier. He realized that any given waveform can…

The Sun in February 2016 and the latest heat records

By Frank Bosse and Fritz Vahrenholt In February 2016 our sun’s activity was, as in almost every month of the current cycle, well below the average. The observed SSN (SunSpotNumber) was 57.2. The average of the cycles 1 … 23 for this month is 80.8, thus the observed activity was 71% of the average value…
