In this paper we present a case study regarding a desert dust intrusion over Central and Eastern Europe in 5th of April 2021, observed using a multi-wavelength Raman and depolarization LIDAR system operated in Cluj-Napoca, Romania. This type of system meets the requirements of the European Aerosol Research Lidar Network – EARLINET and is suitable to provide reliable data on optical parameters for aerosol characterization. While mineral aerosols are the second largest source of aerosol and are the subject of long r...

Improving and protecting water quality, for human needs, and for the sustainability of aquatic ecosystems, has become a global priority for this century, involving continuous monitoring of inland water resources, combining in situ measurements with satellite remote sensing, especially from the surface of the water. This could be possible through the Sentinel missions, respectively S2 and S3 of the European Space Agency, equipped with a multispectral instrument on board, which makes it possible to study inland wate...

Urban areas are very dynamic environments, subject to continuous expansion and growing population, with land use changes influenced by the needs and dynamics of the population. Using remote sensing techniques applied to Sentinel-1 GRD images, some change detection patterns could be revealed for Bucharest city, for a period of three years (2016-2019). As the largest city in Romania, the main university center and the most important industrial and commercial center, Bucharest offers a wide range of educational, inve...

Measurements of high water in rivers are an important element of all collected stream discharge information. It is necessary to have such information in real time during floods because of the danger caused by inundations. Another aspect is the relatively large discharge volume of high water compared to medium and low flow periods. On the other hand, measuring the river discharge during high water with the traditional methods with propeller or floats is often constrained by the manpower availability for that precis...
