haracteristics are suited for studying climate change, energy balance and ecosystems, and may play an important role in
coastal and marine weather prediction and analysis. This study was conducted at Odo Island, approximately 300m from the
mainland in Yeosu. We built a weather observation system capable of real-time monitoring on the mud flat in the intertidal
zone and measured actual weather and marine data. Weather observation was conducted from April to June 2022. The results
showed changes in air temperature and water temperature with changes in the tide level during spring. Correlation analysis
revealed characteristic changes in air temperature and water temperature during the day and night, and with inundation and
exposure.
