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
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
Nitrogen Dioxide Pollution
Nitrogen Dioxide is one of the atmospheric gas species retrieved from the data acquired by Sentinel-5P multispectral imaging spectrometer: TROPOMI. Sentinel-5P is the umpteenth spacecraft belonging the the Sentinels constellations and conceived in the framework of the Copernicus Programme. The main goal of this mission is to perform atmospheric measurements with high spatio-temporal resolution, to be used
