The aim of the studies was to determine many year time and spatial variability of occurrence of main atmospheric deposits in the area of Pomerania (Poland). The studies were carried out on the basis of the Institute of Meteorology and Water Management data including a monthly average number of days with dew, hoar frost, rime and glaze in the years 1971-00, gathered in 16 meteorological stations. The most frequent deposit in Pomerania was dew which was observed on average for 1/3 days during a year. The largest number of days with dew was noticed in August, hoar frost occurred most frequently in December and rime and glaze in January. Statistically a significant decrease in annual number of days with dew was observed in Pomerania in the years 1971-00, whereas no noteworthy trend as to the annual number of days with hoar frost, rime and glaze occurred. In the area of the Polish Coast and particularly in the vicinity of Gdansk Bay and Szczecin Lagoon the atmospheric deposits were on average observed the least frequently as compared to the areas in central parts of Pomerania
