ABSTRACT This research addresses the impact of the COVID-19 quarantine on air pollution in the coastal urban districts of Peru. Utilizing satellite imagery data downloaded from Google Earth Engine, cyclic patterns of air pollution (NO2), economic activity (night lights), temperature, precipitation, and wind speed were examined between the years 2019 and 2020. An immediate average reduction of 40.7% in air pollution was observed after the implementation of the quarantine, followed by a gradual normalization in the subsequent weeks. Furthermore, significant seasonal variations were identified in economic activity, temperature, and precipitation. By employing the Regression Discontinuity in Time (RDiT) model and the Panel Dynamic Fixed Effects (PDEF) model, the negative impact of the quarantine on air pollution was confirmed, with short-term reductions of 16.66% and accounting for seasonality, 18.18%. The influence of factors such as temperature was highlighted, along with the significance of local and international spillovers. This research provides new evidence on the intricate interaction between the health crisis, containment measures, and other factors, emphasizing the importance of spillovers in determining pollution levels.
