Satellite SAR monitoring of the ice cover paraneters of seas closed for navigation of the Russian ships (Bothnia Gulf as example)
The review of a condition now of a representativeness problem in relation to meteorological (including climatic) is submitted to characteristics of environment and points of observation over them, in the Global System of observation, generally, and in the conditions of the insufficient density of a network, characteristic for the Russian Federation, in particular. The analysis of the existing approaches to an assessment of a representativeness of real data and measure of their not representativeness, and also influence of a representativeness of points of supervision on accuracy of the observation data used for various generalizations and statistical calculations is made. It is shown that not accounting of a representativeness of points of observation often leads to absolutely wrong conclusions at further generalizations or interpretation of results of supervision because of not accounting of multiscale of atmospheric processes in formation of the meteorological mode of the territory and (or) the wrong selection of points of the observation suitable for the solution of a specific objective. The attention to extreme importance of the accounting of the "contribution" of a nereprezentativnost of concrete points of supervision representing the powerful numerical characteristic brought in calculations of "climatic characteristics", climate and especially in monitoring of its changes is paid.
