AB  - The use of weather satellite recordings has been growing rapidly over the last three decades.
Determining the patterns between meteorological and topographical features is an important scientific
job. Cloud cover analysis and properties can be of the utmost significance for potential cloud seeding.
Here, the analysis of the cloud properties was conducted by means of Moderate Resolution Imaging
Spectroradiometer (MODIS) satellite recordings. The resolution of used data was 1 km2 within the
period of 30 years (1989–2019). This research showed moderate changing of cloudiness in the territory
of Serbia with a high cloudiness in February, followed by cloudiness in January and November. For
the past three decades, May has been the month with the highest cloudiness. The regions in the east
and south-west, and particularly in the west, have a high absolute cloudiness, which is connected
with the high elevation of the country. By means of long term monitoring, the whole territory of
Serbia was analyzed for the first time, in terms of cloudiness. Apart from the statistical and numerical
results obtained, this research showed a connection between relief and clouds, especially in the
winter season. Linear regression MK (Mann-Kendall test) has proven this theory right, connecting
high elevation sides with high absolute cloudiness through the year.

AB  - Geospatial potential for harvesting wind energy is not an easy task to perform in conditions of deficiency of accurate data in remote and large areas (macro to medium locations). There are different methodologies available to identify the most suitable location for the installation of wind power generators. One of the most suitable approaches that employ the Multi-Criteria Analysis method for wind energy potential of the Municipality of Knjazevac (East Serbia) is combining the Analytic Hierarchy Process (AHP) and Geographic Information Systems. Collection and creation of geospatial data for the research encompassed meteorological data from all available sources, digital elevation model (DEM) to analyze the orography of the terrain, and Landsat 8 satellite data to analyze six land cover (LC) classes. The identification of three best locations for the wind power generators (wind farms) using Multi-Criteria Decision Making (MCDM) analysis solved the major location problem: how to select the best locations for investment in the renewable energy sector and minimize the impact on the environment. The result indicates that only one part of the municipality, at the hub height of 100 m, has enough wind potential to produce energy.

AB  - Recent climate changes cause significant natural and socio-economic consequences. They represent one of the major environmental problems of the late 20th and early 21st centuries. Changes in temperature and precipitation play a significant role in understanding climate change issues. They include numerous extreme climatic events such as heat waves, droughts, forest fires and more. Looking at regional differences in temperature and precipitation regime change, Southern Europe, including the Republic of Serbia, occupies a special place. The Mačva district (3.272 km²) is almost four times as spacious as the Mačva area. The administrative-political division of the Mačva district is comprised of eight municipalities. The paper presents trends of two climate variables: mean annual air temperature and mean annual precipitation in the study area. In methodological sense, the main statistical procedure is the non-parametric Mann-Kendall (MK) test. Data from three available meteorological stations in the Mačva district (1949-2015) were used for the analysis. The presented results of the trends in air temperature indicate that there is a statistically significant positive trend in all-time series. In trends, precipitation amounts a statistically significant positive trend was observed in two time series, while in one there is no trend. The expressed trends, especially in the case of air temperatures, lead to the possibility of drought. Mačva district and Mačva have some agricultural importance in the Republic of Serbia. For these reasons, some adaptation to climate change is needed as arid conditions lead to fluctuations in agricultural yield.

AB  - In the Kopaonik tourist region of Serbia, there are numerous thermal-mineral (TM) springs with an outlet temperature which ranges from 21 to 78.7 degrees C. The main objective of the study is to determine the capacities, thermal power and energy potential of 19 TM springs in 4 spas of this region. This study supports the hypothesis that in the Kopaonik tourist region, TM springs have considerable capacity, as well as heat power and energy potential. The modern method for determining the energy potential and heat power, based on the flow rate, the inlet and outlet temperatures of the TM springs, was applied in the region with rich geothermal sources, and the obtained results were converted to the fossil fuel energy. The research of the given region, using the above method, is more detailed than the previous research carried out at the national level, so the results are more reliable and suggest that similar research should be carried out at the regional and local level. The estimated total heat energy is 758.51 TJ/year, and heat power (capacity) is 24.1 MWt. The TM springs of this region make up 9.06% of the estimated geothermal energy of Serbia and 7.53% of the estimated heat power. The total energy of this region is equivalent to 210697222.3 kW/h (210.7 GWh) or 18116.7 toe and represent significant energy saving potential. The results indicate the possibility of direct use of energy from TM spring and replacement of fossil fuels, which reduces CO2 emissions and positively affects the quality of the environment. The use of geothermal energy will reduce heating costs and ensure electricity supply due to the growing need for it.
