Monthly records of nighttime light are scarce, especially over long periods, yet they are vital for tracking short-term economic shifts and seasonal urban change. This study provides a temporally consistent global 500 m-resolution monthly VIIRS (Visible Infrared Imaging Radiometer Suite)-like nighttime light dataset (1992–2024). By combining DMSP (Defense Meteorological Satellite Program) and VIIRS through reconstruction and correction, a consistent long-term record is created. The dataset supports improved analysis of urban growth and economic activity worldwide.
