# Research data

<hr>

-   **Personal light exposure dataset for Izmir, Türkiye**

<https://zenodo.org/records/16638739>

This repository contains the comprehensive dataset for the MeLiDos field study site of Izmir, Türkiye. Data were collected by Izmir Institute of Technology (IZTECH) and are further processed and analysed by the Translational Sensory & Circadian Neuroscience Unit (TSCN). A detailed description of the experiment is available in Guidolin et al., 2024.
