A harmonized global nighttime light dataset (1992–2023)

Li, X., Y. Zhou*, M. Zhao & X. Zhao (2020) A harmonized global nighttime light dataset 1992–2018. Scientific Data, 7, 168.

We generated an integrated and consistent NTL dataset at the global scale by harmonizing the inter-calibrated NTL observations from the DMSP data and the simulated DMSP-like NTL observations from the VIIRS data. The generated global DMSP NTL time-series data (1992–2018) show consistent temporal trends. This temporally extended DMSP NTL dataset provides valuable support for various studies related to human activities such as electricity consumption and urban extent dynamics.
