	<location>Pyranometer network consisting of 99 number of EKO ML-020VM
		pyranometers setup during HOPE-Juelich campaign was spread in the
		spatial domain covering 50.84 - 50.96 deg. N and 6.35 - 6.51 deg. E
		(i.e., 10 x 12 sq. km).</location>
	<productDescription>EKO pyranometer (Model ML-020VM) provides SW
		broadband downwelling irradiance (in W m-2) at 10 Hz frequency, which
		are then averaged to 1 Hz temporal scale. Each day, all 99 stations
		data are merged into a single file. Data is also provided with
		observational flagging based on cleanliness of the glass dome and
		level balance of the sensor platform. These flags were assigned every
		week during the battery replacement for the entire previous week's
		data of respective pyranometer station. All pyranometers were
		calibrated by the manufacturer.</productDescription>
