Noaa s well known nighttime lights images derive from those satellite data.
Originally designed to view clouds by moonlight the ols is also used to map the locations of permanent lights on the earth s surface.
Nasa researchers have used these images of nighttime lights to study weather around urban areas.
Satellite images of earth at night have been a curiosity for the public and a tool of fundamental research for at least 25 years.
This composite image which has become a popular poster shows a global view of earth at night compiled from over 400 satellite images.
This image of earth s city lights was created with data from the defense meteorological satellite program dmsp operational linescan system ols.
Version 4 of the dmsp ols nighttime lights time series consists of cloud free composites made using all the available archived dmsp ols smooth resolution data for calendar years.
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.
It is sensitive enough to detect lights as small as a single street lamp and even the nocturnal glow produced by the earth s own atmosphere.
