Satellite imagery acquired by Sentinel-1C and Sentinel-2 provides a detailed view of the ports from which the Global Sumud Flotilla (https://globalsumudflotilla.org/) is scheduled to depart: Genoa (Italy), Barcelona (Spain), Tunis (Tunisia), and Sicily (Italy). The mission is organized in two phases: 31 August 2025: vessels will depart from Genoa and Barcelona. 4 September 2025: additional
BIOMASS is an ESA mission designed to improve global estimates of forest biomass and carbon stocks by using a P-band SAR radar, whose long wavelength allows the signal to penetrate vegetation and interact with large structural elements such as trunks and major branches. One of the most powerful features of SAR data is polarimetry: observing
On 8 September at 05:21:44, the European Sentinel-1 radar satellite acquired an image of the Port of Tunis (product: S1A_IW_GRDH_1SDV_20250908T052144_20250908T052209_060892_079552_3FD9.SAFE), showing several vessels belonging to the Global Sumud Flotilla moored at the harbor.Thanks to its radar technology, which operates efficiently regardless of light or cloud cover, the satellite clearly reveals the presence of these humanitarian

On January 7, a magnitude 7.1 earthquake struck Tibet, triggering significant ground displacement. To analyze the surface deformation, I processed Sentinel-1 SLC data from January 5 and January 17 using SNAP, generating an interferogram that reveals how the earthquake reshaped the landscape. (Figure 1).Each fringe (the variation in color in the interferogram) represents a specific
Satellite imagery tells stories that words often cannot. Using Sentinel-2 data, we compare two RGB images of Palestine: one from 2022-12-16 and one from 2024-12-25. Without any additional processing, the transformation is devastatingly clear. The images, captured in RGB with a resolution of 10 meters, provide an unfiltered look at the changes. Sentinel-2’s optical sensors
Cyclone Chido, a powerful tropical storm, swept across Mayotte, leaving a significant impact on the affected regions. Using Sentinel-1 radar data, we analyzed its structure and dynamics through high-resolution imagery and wind field data. On 2024-12-13, Sentinel-1 captured this striking image of Cyclone Chido, showcasing its spiraling rain bands and calm eye. The radar’s ability
The recent floods in Valencia have caused extensive damage. To create a map of the affected areas, Sentinel-1A SAR (Synthetic Aperture Radar) imagery was utilized, offering reliable data to map and identify flooded zones, even under challenging weather conditions and cloud cover. For this analysis, two SAR images from Sentinel-1A were chosen: a pre-event image
A devastating explosion in Beirut on 4 August has killed at least 200 people and injured around 5,000 others. The disaster was preceded by a large fire at the Port of Beirut, on the city’s northern Mediterranean coast, later there was a colossal explosion that sent a mushroom cloud into the air and a supersonic blast
The Black Rock desert is the bed of a large lake that dried up thousands of years ago, by the length of about 130km and located in the northwest of Nevada, in the United States. The flatness of the Black Rock Desert’s lake bed surface has led to the area’s use as a proving ground
The images below represent Wuhan captured with SAR Copernicus Sentinel-1 and optical Copernicus Sentinel-2. Wuhan sits at the confluence of the Han River flowing into the Yangtze River at the East of the Jianghan Plain. The metropolitan area consists of three centers (Wuchang, Hankou and Hanyang) commonly called “Three Towns of Wuhan”. The name Wuhan is obtained by combining
