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
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

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
This image was acquired by Copernicus Sentinel-1 on Lake Pepin on 01/01/2020. It is the first image of this new year and decade. The Lake Pepin was formed by the delta of the Chippewa River, which flows into the Mississippi at the southwestern edge of Wisconsin. It is a naturally border between the U.S. states
Carbon Monoxide is a gas that can be found in our Atmosphere and its presence is mainly due to the burning of fossils fuels and biomass (e.g forest or bushfires) and human activities in general. It is considered a pollutant species of the atmosphere and in this respect the carbon monoxide distribution is an index
In the frame of air quality monitoring the Copernicus Sentinel-5p mission has been designed to identify the concentration of several atmospheric compounds and species in our atmosphere: one of those data is the Ultraviolet Aerosol Indexes (UVAI). Aerosols are a suspension of fine solid particles or liquid droplets, in air or another gas, and can
