At the present state, the LIDAR systems have different configurations and geometries, according to their applications. The multi-wavelength Raman and depolarization LIDAR systems used in the European Aerosol Research Lidar Network ? EARLINET are suitable to provide an extended set of optical parameters for aerosol characterization which can be used in climatology studies, models and different events like Saharan dust outbreaks, transport of smoke plumes or volcanic ash. The aerosol in the atmosphere is present mos...

One of the largest fires in the Croatian history, so called ?mother of all fires?, broke out on Monday, 17. July 2017 in the area between Split and Omis (Croatia). The fighting with the firestorm lasted until 18. July when the situation was put under control, and on 19. July, the recovery of the affected area started. The classification showed that the burned area was 40670 square kilometers large. Vegetation indices obtained from aerial or remote sensing imagery are very simple and effective methods for quantitat...

The microclimate of the urban environment is influenced by urban development, road surface, distribution of green areas. The city, especially with a highly developed industry, pollutes the atmosphere above itself, increases its turbidity and thereby reduces the influx of solar radiation. Such changes in the microclimate of the urban environment often occur as a result of changes in urban development, artificial changes in the relief, and the cutting down of forest plantations. Due to changes in the urban environme...

Monitoring short temporal changes in intra-urban vegetation areas will become very important as the proportion of urban areas continue to increase. Intra-urban variations in vegetation abundance influence environmental conditions by selective reflection and absorption of solar radiation and by sequestration of pollutants. This research investigates the hypothesis that it should be possible to use easily accessible multispectral Landsat 8 images to track intra-urban vegetation, and obtaining sufficient quality info...

More than 50% of the world?s populations live in urban areas, and they emit almost 80% of global carbon dioxide. They are also responsible for 75% of energy consumption in the world. That increases pressure on food, water, and especially energy. These facts imply that there is an urgent need to provide low carbon dioxide level in cities with efficient and renewable energy to foster the growth of the green economy. Therefore, attention should be paid to renewable energy sources such as the Sun and be aware of the p...
