Global Attributes:	Title: Doppler Lidar custom scanning (with varying elevation and azimuth) wind data (3-beams) Institution: Research Center Juelich, Institute for Energy and Climate research (IEK-8) Contact_person: Ulrich Loehnert (Loehnert@meteo.uni-koeln.de) Source: HALO Photonics Doppler lidar (production number 17) History: Data processed with three_beam_wind_hdcp2_0.1.0 and write_three_beam_wind_hdcp2_0.1.0 by University of Cologne Conventions: CF-1.6 where applicable Processing_date: 2014-07-03 15:01:33 (CET) Author: Anne Hirsikko (anne.hirsikko@fmi.fi) Comments: Processed from custom scanning (with varying elevation and azimuth) level 1 data found in HD(CP)2 data base. Three beam wind retrieval. Uncertainty estimate takes into account only radial velocity uncertainty. License: For non-commercial use only. This data is subject to the HD(CP)2 data policy to be found at hdcp2.zmaw.de and in the HD(CP)2 Observation Data Product Standard.
