It is well known that atmospheric aerosols have both a direct and an indirect impact on the Earth's systems and have natural or anthropogenic origins. In this paper we present the results of the 2022 spring-time lidar measurements conducted within the European Aerosol Research Lidar Network (EARLINET) using a multi-wavelength Raman and depolarization LIDAR system operated in Cluj-Napoca, Romania. The Cluj-Napoca lidar system (CLOP) emission is based on a Nd-YAG laser Continuum INLITE II-30, which has a repetition ...

In recent years, the growing impact of flood events on society, economy and environment, has increased the need for early prevention and mitigation measures. The prediction of future flooding areas represents an important tool that can reduce the magnitude of consequences, by identifying and mapping the flood prone-areas. The intensity and extension of floods depends on various contributing parameters, such as hydrometeorological and geomorphological indicators, land use, anthropic activities. Therefore, by analys...

The population and economy growth in the past years, and subsequently the increased demand for freshwater, led to an increased pressure on water resources. The quality of surface water is affected by anthropogenic factors, such as: domestic sewage, industrial activities, agricultural activities, recreational activities, land use change, urbanization. Therefore, the impact on surface water vulnerability is higher in large urban areas or in urban areas with intense touristic activities. The analysis of water vulnera...
