	<location>A total of 50 weather stations were available during
		HOPE-Melpitz campaign and were spread in the spatial domain covering

	<productDescription>Micro-Module for RH (Model No: DKRF 4001-P; Driesen
		+ Kern GmbH ) provides RH at 10 Hz frequency, which are then averaged
		to 1 Hz temporal scale. Each day, all 50 stations data are merged into
		a single file. Data file also includes flags based statistical
		approach. All the micro-module RH sensors were calibrated by the
		manufacturer.</productDescription>
