Alexandrov, M.D., A. Marshak, B. Cairns, and A.S. Ackerman, 2022: Markovian statistical model of cloud optical thickness. Part I: Theory and examples. J. Atmos. Sci., 79, no. 12, 3315-3332, doi:10.1175/JAS-D-22-0125.1.

We present a generalization of the binary-value Markovian model previously used for statistical characterization of cloud masks to a continuous-value model describing 1D fields of cloud optical thickness (COT). This model has simple functional expressions and is specified by four parameters: the cloud fraction, the autocorrelation (scale) length, and the two parameters of the normalized probability density function of (non-zero) COT values (this PDF is assumed to have gamma-distribution form). Cloud masks derived from this model by separation between the values above and below some threshold in COT appear to have the same statistical properties as in binary-value model described in our previous publications. We demonstrate the ability of our model to generate examples of various cloud-field types by using it to statistically imitate actual cloud observations made by the Research Scanning Polarimeter (RSP) during two field experiments.
