Percent frequency of light detections - DMSP-OLS Nighttime Lights
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 coverage - DMSP-OLS Nighttime Lights
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... -
Average of visible band digital values - DMSP-OLS Nighttime Lights
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... -
Average visible per percentage frequency of light detection - DMSP-OLS Nighttime Lights
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... -
Stable lights - DMSP-OLS Nighttime Lights
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,...
