The stability of radiance measurements taken by the Sky Quality Meter (SQM)was tested under rapidly changing temperature conditions during exposure to a stable light field in the laboratory. The reported radiance was found to be negatively correlated with temperature, but remained within 7% of the initial reported radiance over a temperature range of -15 °C to 35 °C, and during temperature changes of -33 °C/h and +70 °C/h.This is smaller than the manufacturer's quoted unit-to-unit systematic uncertainty of 10%,indicating that the temperature compensation of the SQM is adequate under expected outdoor operating conditions.
在实验室中稳定光照条件下,对天空辐射亮度计(SQM)的辐射亮度测量值在快速变化的温度条件下的稳定性进行了测试。结果表明,所报告的辐射亮度与温度呈负相关,但在-15°C 至 35°C 的温度范围内,以及在-33°C/h 和+70°C/h 的温度变化下,仍保持在初始报告辐射亮度的 7%以内。这小于制造商规定的 10%的单元间系统不确定性,表明 SQM 的温度补偿在预期的户外工作条件下是足够的。
