Special Issue Information

Dear Colleagues,

The human environment is currently undergoing rapid and dynamic transformations. These changes are influenced by numerous factors including climate variations, which manifest in phenomena such as droughts, floods, and hurricanes, as well as natural calamities such as earthquakes and volcanic eruptions. Additionally, human activities contribute to environmental degradation through various forms of pollution that affect water, land, and air, including light pollution. This collective impact significantly influences the quality of human life, meaning that there is an urgent need to monitor these changes rigorously, assess their magnitude, and comprehend their environmental ramifications. A deeper comprehension of the underlying processes driving these changes holds the potential to implement precise countermeasures. Leveraging space-based remote sensing methods offers a diverse array of tools that are essential for monitoring environmental shifts.

The objective of this Special Issue is to showcase advancements in the utilization of SAR (Synthetic Aperture Radar) and optical remote sensing data, alongside associated space technologies. These innovations serve as indispensable resources for monitoring environmental phenomena and discerning both natural fluctuations and those induced by human activity.

The power network is directly or indirectly exposed to various weather and climate conditions that can positively and negatively influence it. Forest fires and various aerosol contaminations may negatively affect the power network. Surface observations and measurements (e.g., weather stations) help protect against unfavorable influences, but the network is usually poor. That challenge may be solved by including satellite data in the power network planning, operation, and maintenance. This article presents the possibilities of using Sentinel mission’s data, at various temporal and spatial levels, for those purposes through examples of protection against forest fires and aerosol contamination. In the case of forest fires, satellite data enable a more-precise calculation of forest fire-spreading danger for areas with no installed weather stations, which may be used in the power system contingency analysis calculation. The analysis showed that aerosol contamination has a correlation with outage appearance in the 25 kV 50 Hz electric traction network. Sentinel 5p data may serve as a tool in a surface air-quality measurement data control to confirm/deny the high concentration of PM10 particles. Analysis showed that Sentinel data are favorable for power network operations on intra-day and day-ahead operations, as well as for long-term operations, which include planning and maintenance. The spatial resolution of Sentinel data is more than enough to fulfill the surface weather station network. Satellite data also enable the use of additional data that are not measured at ground stations. Full article
