AI-generated Key Takeaways
-
This collection of datasets provides various nighttime lights data, primarily from the Defense Meteorological Program (DMSP) Operational Line-Scan System (OLS) and the Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band (DNB).
-
DMSP-OLS datasets offer global nighttime lights observations from 1992 to 2013, including calibrated lights, time series, and a consistent and corrected version (CCNL) mitigating inter-annual inconsistencies and saturation effects.
-
VIIRS datasets provide higher resolution nighttime lights data, including annual composites from 2013 to 2022 (V2.1 and V2.2) and monthly composites (V1) with and without stray light correction.
-
These datasets enable analysis of nighttime light emissions, reflecting human activities, urbanization, and environmental changes over time.
-
Users can access both DMSP-OLS and VIIRS nighttime lights datasets, selecting the appropriate dataset based on their specific needs for temporal and spatial coverage, data quality, and processing levels.

VIIRS Nighttime Day/Night Annual Band Composites V2.1
Annual global VIIRS nighttime lights dataset is a time series produced from monthly cloud-free average radiance grids spanning 2013 to 2021. Data for 2022 are available in the NOAA/VIIRS/DNB/ANNUAL_V22 dataset. An initial filtering step removed sunlit, moonlit and cloudy pixels, leading to rough composites that … annual dnb eog lights nighttime noaa -
VIIRS Nighttime Day/Night Annual Band Composites V2.2
Annual global VIIRS nighttime lights dataset is a time series produced from monthly cloud-free average radiance grids for 2022. Data for earlier years are available in the NOAA/VIIRS/DNB/ANNUAL_V21 dataset. An initial filtering step removed sunlit, moonlit and cloudy pixels, leading to rough composites that contains … annual dnb eog lights nighttime noaa -
VIIRS Nighttime Day/Night Band Composites Version 1
Monthly average radiance composite images using nighttime data from the Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band (DNB).
