ABSTRACT
In order to control the spread of the pandemic of Corona-Virus Disease 2019 (COVID-19), lockdowns of various durations and intensities have been established in many countries over the world all through the year 2020. The trilateral dashboard jointly implemented by NASA, JAXA and ESA aims at exploiting remote-sensing data to evaluate the impact of these restrictions, and subsequent recovery phases on many different environmental, agriculture and economic indicators. More specifically, this paper presents the indicators implemented to monitor the impact of COVID-19 restrictions on Water Quality, together with preliminary analysis results over a few Areas of Interest. © 2021 IEEE.
ABSTRACT
COVID-19 lockdown measures brought to a drastic reduction of anthropic impacts on the environment, including the marine-coastal system. EO data have the potential to monitor and diagnose the subsequent effects of the lockdown in terms of water quality. The ESA-RACE project SOON aims to link complex patterns that may arise from the environmental changes due to COVID-19 lockdown by using EO data, also seeking to assess connectivity between inland and marine system. Within this frame, here we present a holistic, satellite-based analysis of the spatial-temporal variability of environmental parameters in the North Adriatic Sea (NAS;Mediterranean basin), exploiting the synergy of OC and SST products from different sensors, as well as in situ hydrologic data. Our analysis indicates a favorable interplay of environmental variability and reduction of anthropogenic activity that results in negative anomalies of Chlorophyll-a and Total Suspended Matter with respect to the climatologic values. © 2021 IEEE
