DMSP Night Lights (1992 - 2013)⚓︎

Table Summary⚓︎

The Defense Meteorological Program (DMSP) Operational Line-Scan System (OLS) has a unique capability to detect visible and near-infrared (VNIR) emission sources at night. In cases where two satellites were collecting data, two composites were produced.

Note

  • Missing %: Proportion of observations with missing data
  • Zero %: Proportion of observations with zero values
  • Canary variable: The ⭐ indicates the canary variable for imputation, see this link for more details about the imputation algorithm.
