Abstract：
The use of remote sensing and GIS methodology has accelerated the processing of data on pollution, but has also raised a question about the accuracy of the same. The research focuses on four main air pollutants (CO, NO, SO2, O3), the data on which were obtained from satellite images of Landsat 8 and Landsat 9, for the period 2000-2020. The data on relative cloudiness were obtained from the database CHELSA (Climatologies at high resolution for the earth\'s land surface areas) for the period 1980-2010. All the data were further processed and analyzed through the procedures of numerical GIS analysis, multi-criteria analysis, supervised and unsupervised satellite classification, and pixel analysis. The results of the analysis of cloud cover in the Balkan region showed that the month with the highest cloud cover in this period was February, with the maximum of (93.18%), whereas the lowest cloud cover was in July (0.19%). The analyzed period (2000-2010) was in the middle range for the pollutants NO and SO2 and in the lower range for CO; O3. In the period 2010-2020, there were high concentrations of NO, SO2, and CO and low concentrations of O3. The most polluted cities in the last twenty years are Ordu (Turkey), Sarajevo (Bosnia and Herzegovina), and Bor (Serbia). Finally, two most extreme air pollutants in the territory of Balkan countries were SO2 and NO (2000-2020).
摘要：
遥感和地理信息系统方法的使用加速了污染数据的处理,但也提出了一个关于准确性的问题。研究重点是四种主要的空气污染物(CO，NO,SO2、O3)、从2000-2020年期间Landsat8和Landsat9的卫星图像中获得的数据。1980-2010年期间，从CHELSA数据库（地球陆地表面区域的高分辨率气候学）获得了有关相对云量的数据。通过GIS数值分析的程序对所有数据进行了进一步的处理和分析,多准则分析，有监督和无监督卫星分类，和像素分析。巴尔干地区云量分析结果表明,这一时期云量最高的月份为二月,最大值为（93.18%），而最低的云量是在7月份(0.19%)。分析期间（2000-2010年）对于污染物NO和SO2处于中间范围，对于CO；O3处于较低范围。在2010-2020年期间，有高浓度的NO，SO2，而CO和低浓度的O3。过去二十年来污染最严重的城市是Ordu（土耳其），萨拉热窝(波斯尼亚和黑塞哥维那),和Bor（塞尔维亚）。最后,巴尔干国家领土上两种最极端的空气污染物是SO2和NO（2000-2020）。
