data required for replication for the article "Spectroscopic study of the light-polluted night sky in Hong Kong"

Spectroscopic study of the night sky has been a common way to assess the impacts of artificial light at night at remote astronomical observatories. However, the spectroscopic properties of the urban night sky remain poorly documented. We addressed this gap by collecting more than 12,000 zenith sky spectra with compact spectrometers at urban and suburban sites from 2021 to 2023. Here we provide raw data (grouped by observing locations) required for replication for the article "Spectroscopic study of the light-polluted night sky in Hong Kong".Journal reference: Journal of Quantitative Spectroscopy and Radiative Transfer, Volume 348, January 2026, 109696, https://doi.org/10.1016/j.jqsrt.2025.109696
