The Detrended Fluctuation Analysis statistical method is applied to microwave radiometer and infrared thermometer radiance data in order to examine stratus cloud dynamics. The existence of long-range power law correlations in stratus cloud liquid water path and radiance (brightness temperature) fluctuations is demonstrated to occur over about a two-hour period. Moreover, using a finite-size (time) interval window, a change from non-Brownian to Brownian fluctuation regimes is clearly shown to define the cloud structure changes.
