El conjunto de datos de Luces nocturnas coherentes y corregidas (CCNL) es una versión reprocesada del Sistema de exploración lineal operacional (OLS) de la versión 4 del Programa de Meteorología de Defensa (DMSP). Se usaron una serie de métodos para mitigar el impacto de la inconsistencia interanual, la saturación y los efectos de floración, y para mejorar la calidad de los datos. La versión 1 de la CCNL abarca…
