Аннотация: Представлен анализ современного состояния структурно-стратиграфических исследований снежного покрова и перспективы использования подобных данных.The paper presents an analysis of the recent state and the gaps in recent understanding and use of the structural and stratigraphic data for snow cover. It is pointed out that, despite considerable amount of data on intraseasonal and interannual variability on snow cover extent, on snow water equivalent and on snow cover depth, in large part being in digitized form, there are either no or very few data on the snow cover properties. The latter determined by snow structure and snow cover stratigraphy. The applied aspects of the investigation of the snow structure and snow cover stratigraphy are practically absent in the ongoing scientific programmes on cryosphere research, although these aspects served as the reason for establishing the observational network in XIX century and were extensively discussed up to the middle of XX century. A review of the methods of the snow structure presentation (snow classification and snow cover classifications) is provided. The results and prospect of the development of snow cover models of different spatial and temporal scales are discussed. A number of new promising direction of structural and stratigraphic snow cover investigation are suggested as an addition to the traditional topics. These are Estimation of the snow cover properties based on spatial variability of landscape-climatic conditions; the snow cover influence on gas exchange and biological activity at the border between soil and the atmosphere; the influence of snow metamorphism activity on post-depositional change of stable water isotopes content of snow (related to paleoclimate reconstruction from the buried ice bodies), etc. http://elibrary.ru/item.asp?id=17349038
