Аннотация: The recovery problem of the power and effective height of an admixture source using the measurement data of the near-earth-surface concentration is considered on the basis of semi-empirical equation solution of turbulent diffusion. A technique is suggested for solution of the inverse problem and numerical construction of the optimal observations plan. There is passed an evaluation test of the suggested models of observations planning and source parameters estimation by using the data of field investigations in the neighbourhood of steam electric power station in Dikkerson. The experimental and recovered source parameters are in satisfactory agreement.

Аннотация: The problem of temperature anomalies is typical for all major cities in the world. Space thermal images are a powerful source of information for analyzing and determining outlines of temperature anomalies within a single territory. Determination of the nature and boundaries of temperature anomalies will help to understand the causes of the unfavorable ecological situation in Krasnoyarsk: where, in addition to high industrial emissions, atmospheric processes also exert their influence, which lead to the fact that impurities linger and concentrate over the city. The development of advanced space technologies allows the collection of a variety of diverse data more efficiently and at a lower cost than the organization of an appropriate ground network of observation posts and points. One of the most interesting and important indicators about the surface of the Earth is the land surface temperature. Land surface temperature is determined by the balance of incoming and outgoing energy. The main and overwhelming source of energy coming to the surface of the Earth is solar radiation. The 10th and 11th bands of Landsat 8 satellite measure thermal infrared radiation (TIR). The thermal infrared range is particularly useful for determining the temperature difference between the city and surrounding rural areas, and for studying the phenomenon of an urban heat island (UHI).
Проблема температурных аномалий характерна для всех крупных городов мира. Космические тепловые снимки являются весомым источником информации для анализа и определения контуров температурных аномалий в пределах одной территории. Определение природы и границ температурных аномалий поможет понять причины неблагоприятной экологической ситуации в Красноярске: где, помимо высоких промышленных выбросов, оказывают влияние атмосферные процессы, которые приводят к тому, что примеси задерживаются и концентрируются над городом. Развитие передовых космических технологий позволяет осуществлять сбор множества разнообразных данных более эффективно и с меньшими затратами, чем организация соответствующей наземной сети пунктов и постов наблюдения. Одним из наиболее интересных и важных показателей о поверхности Земли служит температура земной поверхности. Температура на поверхности Земли определяется балансом приходящей и уходящей энергии. Основным и подавляющим источником энергии, поступающей к поверхности Земли, является солнечное излучение. Каналы 10-й и 11-й Landsat 8 работают в том же диапазоне, что и канал TIR на более ранних спутниках программы Landsat. Каналы 10-й и 11-й спутника Landsat 8 измеряют тепловое инфракрасное излучение или TIR (thermal infrared). Разрешение для тепловых каналов 100 м.

Satellite data in the thermal infrared range are a powerful source of information for analyzing and determining of temperature anomalies. Determination of the nature and boundaries of temperature anomalies will help to understand the causes of the unfavorable ecological situation in Krasnoyarsk: where, in addition to high industrial emissions, the atmospheric processes also exert their influence, which may cause the impurities linger and concentrate over the city. This paper presents a technique for monitoring the land surface temperature on the basis of thermal infrared data from the 10th band of Landsat 8 satellite. Ground-based temperature data from an environment protection state regional system for observing the state of the atmosphere in the Earth's surface layer are used. The results show that the temperature in the places of temperature anomalies is 5-8 degrees higher than the average surface temperature of the city. Based on the results of an analysis of summer thermal multi-temporal space images, several thermal zones of different nature are outlined in the territory of the city. © Published under licence by IOP Publishing Ltd.

Аннотация: Satellite data in the thermal infrared range are a powerful source of information for the analysis and determination of city urban area temperature anomalies. The article presents a technique for monitoring the land surface temperature on the basis of combination of "Landsat 8" satellite thermal infrared data with Planet-Scope satellite constellation high resolution data. Such combination of satellite data from several spacecrafts increase the detalization of temperature maps to the level of individual city blocks. Determination of the nature and boundaries of temperature anomalies will help to understand the causes of the unfavorable environmental situation in Krasnoyarsk, where, in addition to high industrial emissions, their influence and atmospheric processes, leading to the fact that impurities are delayed and concentrated over the city. The results shows that the temperature in the places of thermal anomalies is 5-8 higher than the average land surface temperature of the city. Based on the results of the analysis of summer thermal multi-temporal space images, several thermal zones of different nature were outlined on the territory under consideration. This information can be used in planning the development of the city, the design of new urban neighborhoods.
