Abstract
A statistical space-time model of rainfall has been developed. The model is based on rain gage and radar data. The radar data required by the model are 0-1 mosaics: 0-indicates no rain, 1-indicates occurrence of rain. Such form of radar data can be easily obtained from radar echo images. The radar data are used to model the spatial patterns of rainfall and the raingage data are used to model the magnitude of rainfall. The potential applications of the model to study the so-called ground-truth techniques, useful in verification of rainfall estimation methods, are discussed. The focus of this paper is on the parameter estimation problem. An estimation method of model parameters is presented and investigated via a simulation experiment. The experiment provides means to study the properties of the parameter estimators under a wide-range of sampling and measurement error conditions. Also, other issues concerning sampling strategies of space-based observations and the model are addressed.
