A precipitation occurrence model (Q1864471)

Real time occurrences of rain and snowfall are of interest for modeling and increasing purposes, in problems addressing relations between precipitation and wet chemistry technology. An imbedded renewal process as a model of precipitation occurrence is fairly well known. Data permitting verification of assumptions determining such a model, for example independence and distribution of sojourn times, are available rather rarely, however, due to problems with definition of a precipitation. An operational definition of a precipitation is obtained by associating the precipitation occurrence with an opening sojourn time of a precipitation collector. This paper describes identification of the renewal model using such definition and applies the model to compare several different precipitation collectors.
