New images processed on ONDA showing the effects of the coronavirus lockdown on air quality
Further to our first article on The effects of the coronavirus lockdown on air quality: a comparative analysis of satellite data, more images have been processed on the ONDA platform in order to compare the presence of nitrogen dioxide (NO2) in the atmosphere before and during the coronavirus lockdown.
Data from Sentinel-5P have been used to map the average distribution of the tropospheric concentration of NO2 from multiple acquisitions during the period 15 March-15 April 2020, and compared to the same period of the previous year (15 March-15 April 2019).
More information on the analysis and the NO2 values can be found here.
