TL;DR
This paper discusses the optical noise monitoring system of Lake Baikal's environment using the Baikal-GVD neutrino telescope, highlighting observed variations in luminescence activity over several years and validating data consistency.
Contribution
It introduces a method for monitoring optical noise in Lake Baikal using the Baikal-GVD telescope and compares two independent data sets for validation.
Findings
Luminescence activity increased in 2016 and 2018.
Optical noise remained constant in 2017.
Independent data sets show good agreement.
Abstract
We present data on the luminescence of the Baikal water medium collected with the Baikal-GVD neutrino telescope. This three-dimensional array of light sensors allows the observation of time and spatial variations of the ambient light field. We report on observation of an increase of luminescence activity in 2016 and 2018. On the contrary, we observed practically constant optical noise in 2017. An agreement has been found between two independent optical noise data sets. These are data collected with online monitoring system and the trigger system of the cluster.
