Global Calibrated Nighttime light at a 1km spatial resolution (1992-2013)

Li, X.; Zhou, Y. A Stepwise Calibration of Global DMSP/OLS Stable Nighttime Light Data (1992–2013). Remote Sens. 2017, 9, 637.

We developed a temporally consistent NTL dataset using a stepwise approach to calibrate the NTL time series. Each step was designed to calibrate particular satellites (or years) with systematic over- or under-estimation. Our calibrated NTL observations show a temporally more consistent pattern of NTL time series, as well as a good agreement with socioeconomic data, such as GDP and electricity consumption.

Spatial Resolution: 1km; Temporal Resolution: Annual; Temporal Coverage: 1992-2013
