Harmonization of DMSP and VIIRS nighttime light data from 1992-2021 at the global scale
The dataset contains (1) temporally calibrated DMSP-OLS NTL time series data from 1992-2013; and (2) converted NTL time series from the VIIRS data (2014-2021)
Spatial resolution: 30 arc-seconds (~1km)
Information about the composited images from the calibrated DMSP dataset:
F10(1992-1994); F12(1995-1996); F14(1997-2003); F16(2004-2009); F18(2010-2013)
We suggested using pixels with DN values greater than 7.
