Why night-time lights data? One approach we have been experimenting with, though, is high-resolution, night-time lights data, which is captured daily by satellite. All cities experienced large declines in lights, but the pace of recovery is unevenSo, what does the monthly lights data show? Prior to the COVID-19 crisis, cities were, on average, close to their long-run growth trends, as estimated using monthly lights data going back to April 2012. Moving forward, we will explore the potential for fusing lights data with other high-frequency data, such as on nitrogen dioxide concentrations and traffic congestion.
