Scientific Gateway for Evaluating Land-Surface Temperatures Using Landsat 8 and Meteorological Data over Armenia and Belarus
Abstract
The article introduces a scientific gateway to assess land surface temperatures using Landsat 8 and visible infrared imaging radiometer suite data. The gateway offers a selection of four temperature retrieval algorithms and two interpolation methods to create time series. The evaluation of the gateway’s performance in Armenia from May to October 2022 is illustrated. The research identifies the Price, Jiménez-Muñoz, McMillin, and I05 Chanel algorithms as the most accurate nighttime temperature estimation. Additionally, these products exhibit a reasonable level of accuracy, with an average root mean squared error ranging from 2.42 to 2.45°C and a coefficient of determination spanning from 0.82 to 0.95. The outcomes of this study bear significant relevance for diverse applications such as urban heat island analysis, environmental monitoring, and agricultural assessments.
期刊介绍：
The purpose of the journal is to publish high-quality peer-reviewed scientific and technical materials that present the results of fundamental and applied scientific research in the field of image processing, recognition, analysis and understanding, pattern recognition, artificial intelligence, and related fields of theoretical and applied computer science and applied mathematics. The policy of the journal provides for the rapid publication of original scientific articles, analytical reviews, articles of the world''s leading scientists and specialists on the subject of the journal solicited by the editorial board, special thematic issues, proceedings of the world''s leading scientific conferences and seminars, as well as short reports containing new results of fundamental and applied research in the field of mathematical theory and methodology of image analysis, mathematical theory and methodology of image recognition, and mathematical foundations and methodology of artificial intelligence. The journal also publishes articles on the use of the apparatus and methods of the mathematical theory of image analysis and the mathematical theory of image recognition for the development of new information technologies and their supporting software and algorithmic complexes and systems for solving complex and particularly important applied problems. The main scientific areas are the mathematical theory of image analysis and the mathematical theory of pattern recognition. The journal also embraces the problems of analyzing and evaluating poorly formalized, poorly structured, incomplete, contradictory and noisy information, including artificial intelligence, bioinformatics, medical informatics, data mining, big data analysis, machine vision, data representation and modeling, data and knowledge extraction from images, machine learning, forecasting, machine graphics, databases, knowledge bases, medical and technical diagnostics, neural networks, specialized software, specialized computational architectures for information analysis and evaluation, linguistic, psychological, psychophysical, and physiological aspects of image analysis and pattern recognition, applied problems, and related problems. Articles can be submitted either in English or Russian. The English language is preferable. Pattern Recognition and Image Analysis is a hybrid journal that publishes mostly subscription articles that are free of charge for the authors, but also accepts Open Access articles with article processing charges. The journal is one of the top 10 global periodicals on image analysis and pattern recognition and is the only publication on this topic in the Russian Federation, Central and Eastern Europe.
