✦ Synopsis

Laboratory measurements of the autocorrelation and space-time correlations for probe separations alined with the mean flow are used to test a hypothesis of Pielke and Panofsky (1970) whichrelates these measures by means of anempirical decay parameter taken fromcoherence data. The direct laboratory measurements of the space-time correlations are in good agreement with the functions estimated using the method of Pielke and Panofsky (1970). However, the decay parameters implied for the laboratory measurements are much smaller than those reported for atmospheric turbulence.

In this paper, a class of product-sum covariance models has been introduced for estimating and modeling space-time correlation structures. It is shown how the coe cients of this class of models are related to the global sill and "partial" spatial and temporal sills; moreover, some constraints on the

A generalized model for time series count data with serially correlated random e ects is introduced to establish robust inference procedures.
