Carbon Monoxide
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 … Continue reading Carbon Monoxide
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 … Continue reading Aerosols
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 … Continue reading Land Surface Temperature
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 … Continue reading Formaldehyde

Mappamondo: Copernicus Natural Color World
Since we started to publish Sentinel-3 Level 2 world maps via our EO browser we took the challenge to process a land worldwide cloud free image of the Earth with an RGB natural colour composition. Indeed with a proper tailoring of … Continue reading Mappamondo: Copernicus Natural Color World
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 … Continue reading Time Series of Sentinel-3 Data
