The Difference

The mapping and analysis of the dates of onset and melting the snow cover in the Baikal region for 2000–2010 based on eight-day MODIS “snow cover” composites with a spatial resolution of 500 m, as well as their verification based on the data of 17 meteorological stations was carried out. For each year of the decennary under study, for each meteorological station, the difference in dates determined from the MODIS data and that of weather stations was calculated. Modulus of deviations vary from 0 to 36 days for onset dates and from 0 to 47 days – for those of stable snow cover melting, the average of the deviation modules for all meteorological stations and years is 9–10 days. It is assumed that 83 % of the cases for the onset dates can be considered admissible (with deviations up to 16 days), and 79 % of them for the end dates. Possible causes of deviations are analyzed. It was revealed that the largest deviations correspond to coastal meteorological stations and are associated with the inhomogeneity of the characteristics of the snow cover inside the pixels containing water and land. The dates of onset and melting of a stable snow cover from the images turned out to be later than those of weather stations for about 10 days. First of all (from the end of August to the middle of September), the snow is established on the tops of the ranges Barguzinsky, Baikalsky, Khamar-Daban, and later (in late November–December) a stable cover appears in the Barguzin valley, in the Selenga lowland, and in Priolkhonye. The predominant part of the Baikal region territory is covered with snow in October, and is released from it in the end of April till the middle of May.

Currently, the most popular are the express methods of quality control of the environment, which permit a relatively rapid assessment of ecological and geochemical situation. one such method is based on the use snow cover. snow has a high sorption capacity and is informative in identifying the object of man-made pollution of the urban environment. the paper presents the results of a study of the chemical composition of snow that had fallen in Voronezh during winter 2015. snow samples were taken in the period prior to snowmelt in various functional areas of the city. in order to identify the degree of technogenic impact on the various parts of the city of Voronezh, was made a comparative analysis of the results:аccording to the actual presence of pollutants in precipitation for the study of functional areas;сalculate the rate on the concentration of chemical elements for test samples of snow.according to the degree of mineralization and dust content in snow can be seen technogenic pressure on environment.therefore, a comparative analysis of the degree of contamination of snow in the various functional areas of the city were carried out for the two indicators of the chemical composition - the total mineralization and suspended particles(dust).the results of the analysis of the chemical composition of the melt water indicate an increased level of technogenic pollution of snow cover in all investigated functional areas of Voronezh.
