A dynamic model for short-scale rainfall disaggregation

Koutsoyiannis, D., and Th. Xanthopoulos, A dynamic model for short-scale rainfall disaggregation, Hydrological Sciences Journal, 35 (3), 303–322, 1990.



The single-site dynamic disaggregation model developed and presented in this paper is a generalized step-by-step approach to stochastic disaggregation problems. The forms studied concern low-level variables with Markovian structure and normal or gamma marginal distributions. Combined with a rainfall model, the disaggregation scheme gives a rainfall generator, transforming monthly rainfall into events and hourly amounts. A particular application of the generator, based on historical data, is used to illustrate and test the model.
