Aerosols

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

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

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

Cebile storm over the Indian Ocean

During the last days in the remotest parts of the Indian Ocean a tropical cyclone was formed. Its name is Cebile and he reached the category strength 4. The storm was luckily formed far away from Madagascar, Sri Lanka and other inhabited islands, thus avoiding many damages and casualties. The cyclone has been captured by

Upwelling over the Adriatic Sea

The last November 22th the Copernicus Sentinel-3A satellite captured a long stream of discolored water over the entire Adriatic Sea coast of Italy. This singular sight from the outer space is fascinating and the wide impacted area is perfectly exploited by the natural-color RGB image showed below. What’s that about and how it came into

Volcanoes seen by Sentinel-2

On Earth, 500-600 Volcanoes exist. A volcano is a relief of the terrestrial crust (submarine or air) formed by the ejection and stacking material from the rise of magma in the form of lava ash. Volcanic activity can take several forms; each of them depends on the quantity of gases present in the magma and

Swimming in the Clouds

Clouds are visible bodies of very fine water droplets or ice particles suspended in the atmosphere. The origin of term “cloud” can be found in the old english clod or clud, meaning a hill or a mass of rock. Around the beginning of the 13th century the term cloud was then intended as a metaphor to include rain clouds as masses of evaporated water
