ibutton temperature measurements - Vallon de Nant

<pre>A field campaign was set up from July 2021 to September 2023 in order to have in-situ temperature measurements, which represent an additional data source for estimating the performance of the temperature products and better describe the local site effects in the valley. A series of 28 mini-temperature sensors (ibutton loggers) distributed in the basin is installed, in particular at the bottom of the valley. 28 loggers (12 masts + 18 single loggers) were installed in August 2021. The data were recorded in August 2022 and the loggers were finally uninstalled in September 2023. The sensors are installed on a mast, under a plastic shelter at 2 m from the ground. The measurement time step is 2 hours. </pre>
