Remote Sensing in Earth Systems Sciences

Abstract Empirical satellite-derived bathymetry (SDB) encompasses methods that can predict depths in optically shallow water bodies by correlating seabed reflectance with in situ measurements. Over the past few decades, advances in these techniques have enabled the accurate, robust, and accessible mapping of diverse shallow-water environments worldwide. In this study, we evaluated the potential o…

Accurate precipitation measurement is essential for climate, hydrological, and agronomic studies. However, in regions such as the Amazon, the scarcity of rain gauges and frequent gaps in historical series pose a significant challenge for long-term analyses. This study evaluated the performance of satellite and gridded precipitation estimates for gap-filling daily rainfall data recorded between 20…

The Beaufort Gyre (BG) in the Arctic Ocean has experienced rapid changes in losing extensive amounts of sea-ice and undergoing freshening over the past few decades. In this study, we highlight important recent changes in BG’s surface circulation, and its impact on freshwater (FW) fluxes and freshwater content (FWC) and draw attention to the critical importance of continuous monitoring of BG dynam…

Abstract Imaging spectroscopy enables detailed recording of the Earth’s surface and ecosystems’ properties at a global level. Due to the specifications of the hyperspectral sensors, it becomes possible to utilize the hyperspectral data in a multitude of applications, among which the mapping, monitoring and understanding of land use and land cover (LULC). The Environmental Mapping and Analysis Pro…

Abstract Accurate and timely mapping of crops is essential for water resource management and to ensure sustainable food security. Satellite remote sensing has the well-documented ability to provide crop-type maps based on multispectral temporal datasets. However, due to the highly heterogeneous cropping practices, crop type mapping usually involves large phenological datasets, complex procedures,…

Abstract Active volcanic areas with intense explosive activity are often affected by secondary hazardous phenomena, such as wildfires triggered by incandescent ballistic material that hits vegetated zones. A testimony of this was the wildfire induced by the 3rd of July 2019 paroxysm at Stromboli Island (Aeolian Archipelago, Italy). This wildfire involved significant portions of territory and caus…

Abstract Accurate rainfall measurement is vital when investigating spatio-temporal precipitation variability, especially in arid lands. However, there are regions worldwide where only a few ground-based observations are made. This research evaluated the applicability of six satellite precipitation products (SPPs) in detecting rainfall variability in North Darfur State, Sudan. The SPPs were Tropic…
