## Editorial
World Bank Light Every Night (LEN) is an open archive of nightly nighttime light observations assembled from two sensor families. The DMSP-OLS component spans 1992-2017, drawn from six DMSP satellites (F10, F12, F14, F15, F16, F18); the World Bank LEN readme gives 2017 as the DMSP upper bound while the AWS Open Data registry entry references an earlier subset.[^worldbank-len-readme][^aws-registry] The VIIRS-DNB component covers 2012-2020; extension beyond 2020 was not confirmed as of 2026-06-11.[^worldbank-len-readme] The archive is developed by the World Bank in collaboration with NOAA and the University of Michigan, and is distributed via the AWS Open Data Programme.[^aws-registry] Access is open.
