A research developed at RSLab by analyzing satellite images acquired by the planet constellation points out that the amount of total suspended matter in the Venice lagoon has been halved after the first 10 days of lockdown due to COVID-19 in March 2020. The same study also points out that the amount of total suspended matter has been doubled during the exceptional tides of November 2019. The study (which has been published on an international scientific journal) has spread to the general public by different newspapers.
