Stability of the Nine Sky Quality Meters in the Dutch Night Sky Brightness Monitoring Network [PDF]
Sensors, 2015 In the context of monitoring abundance of artificial light at night, the year-to-year stability of Sky Quality Meters (SQMs) is investigated by analysing intercalibrations derived from two measurement campaigns that were held in 2011 and 2012.

Long-Time Trends in Night Sky Brightness and Ageing of SQM Radiometers
Remote Sensing, 2022 A very wide-used instrument for the measurement of the Night Sky Brightness (NSB) is the Sky Quality Meter (SQM). One of its important issues is tracking NSB for long time and connecting its variations to changes in outdoor lighting.
