Percent frequency of light detections (pct_lights) in cloud-free observations. The number of light detections is not provided but can be calculated by multiplying pct_lights by the number of...

Cloud-free coverages (cf_cvg) tally the total number of observations that went into each 30 arc second grid cell. This image can be used to identify areas with low numbers of observations where the...

The Stable lights image is the cleaned up version of the avg_vis image containing the lights from cities, towns, and other sites with persistent lighting, including gas flares. Ephemeral events,...

The row image (avg_vis) contains the average of the visible band digital number values with no further filtering. Data values range from 0-63. This composite set is a component of the DMSP-OLS...

This nighttime lights product known as avg_lights_x_pct is derived from the average visible band digital number (DN) of cloud-free light detections multiplied by the percent frequency of light...
