Relative humidity, Medenine, Tunisia

Relative humidity is measured at 0.1 Hz using a HMP60 temperature & relative humidity probe (Campbell® Scientific Instruments). The HMP60 probe is located in a naturally ventilated 10-plate radiation shield at 2 m height from the flat roof of the highest building of the campus of the Institut des Régions Arides (IRA) de Medenine (i.e., about 14.5 m above the ground level). The relative humidity in percent (%) is recorded as 5 min averages using a CR200X datalogger (Campbell® Scientific Instruments) and distributed as 1 hour averages (UTC). The value reported for 01:00UTC represents the average over the past hour, and so on (the number of values used to compute the average is given for each time step).
