Mapping the Valencia Floods with Sentinel-1
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
Land Surface Temperature
“Land Surface Temperature (LST) is the radiative skin temperature of the land derived from solar radiation. It is a basic determinant of the terrestrial thermal behaviour, as it controls the effective radiating temperature of the Earth’s surface” [1]. LST is linked to several aspects of the geoscience and in this respect the understanding of its
Formaldehyde
Formaldehyde is an organic compound widely used in many industrial applications, such as the manufacturing of resins, production of disinfectants and biocides or like a tissue fixative. It is present in our atmosphere as a gas and its distribution in the air is not only linked to man-made sources (combustion of fuel, traffic, emission from
The Ozone Hole
All life on Earth depends on the existence of a thin shield of a poisonous gas high in the atmosphere: the ozone layer. (Ozone Secretariat, UNEP, “Action on Ozone”) The ozone layer is a region of our atmosphere widely known for absorbing a large part of the direct dangerous ultraviolet radiation coming from the Sun. Indeed
Time Series of Sentinel-3 Data
One of the mission needs of Sentinel-3 constellation is directly related to the evaluation of climate change effects on Earth. Indeed the spacecrafts and their payloads haven’t been designed to identify small objects on the ground but to revisit the same region with high frequency. In this respect we have created four different animations in
Oceans Mapping with Sentinel-3
Our third step in the framework of World health monitoring and evaluation of climate changes effects on Earth stands on oceans and seas mapping. Copernicus Sentinel-3 mission, as already described for land products, systematically delivers to the community a large dataset of marine products, namely geophysical data extremely useful for the monitoring purposes we described
World Land Mapping with Sentinel-3
The last week we have advertised our new born project aiming to reach a global land and marine monitoring of the World with Sentinel-3. Indeed this mission offers a large dataset of geophysical data really usefull in the framework of the evaluation of climate change effects on Earth. In order to do that and thus
Level 3 Mosaics over Africa
Copernicus Sentinel-3 mission has been designed and developed mainly to focus on the climate changes effects impacting on our planet and is carrying on board several instruments with medium-low resolution in order to pursuit this goal. From this perspective the main strength of the project is not standing in the capabilities to distinguish small objects
Burian
The last week a large part of the Europe has been smashed by a wave of cold siberian weather carried by the Burian. Burian is a strong wind of cold air and it is indeed characteristic of the steppes located to the west of the Urals. The extremely cold air carried by Burian leds to
Mississippi River System
Learning about the Earth with Copernicus Space missions. The Mississippi river system is one of most complex water bodies system all around the World. The main river is around 3700 km long, its flow is feed by tenths of tributaries and its path cross a large number of states over the entire US territory. Thanks
