Target categorization based on multiwavelength and polarization (Raman) lidar data
Limitations: none
Provenance: Polly-XT Multiwavelength Raman polarization lidar calibrated attenuated backscatter coefficient and volume depolarization ratio
Comments: This dataset is based on data processed with cloudnet. Cloudnet is member of ACTRIS and data is available for numerous sites in addition to those of HD(CP)2. See http://actris.nilu.no/ for details. There is a distinct data policy agreement between HD(CP)2 and ACTRIS to manage the sharing of datasets between both projects. The nc conventions of the original cloudnet-nc-files were slightly modified to fit HD(CP)2 file conventions. In addition, not all variables of the original cloudnet-nc-files are contained in the HD(CP)2 files. The original comments and global arguments of cloudnet present in the nc files were renamed to *cloudnet_ARGUMENT_NAME*.
Instrument 1

Licence
- Both ACTRIS and HD(CP)2 scientific steering committees (SSCs) agree, that all Cloudnet products are substantial for multiple applications in atmospheric science related to cloud-processes and should thus be made easily and freely available to atmospheric scientists world-wide.
- The original and citable Cloudnet data from all ACTRIS and HD(CP)2 atmospheric observatories (AO or termed supersites) are available through the Cloudnet web site ( http://www.cloud-net.org ) or the ACTRIS data centre ( http://actris.nilu.no/ ). Currently, Cloudnet data is created locally on the respective AO server and then transferred to the Cloudnet server in Reading, UK.
- An exception to 2.) are the Cloudnet data from the atmospheric observatories LACROS (Leipzig), JOYCE (Juelich) and RAO (Lindenberg) during the course of HD(CP)2. Currently HD(CP)2 is developing an Observation Data Product Standard for its atmospheric column, respectively full-domain data needed for the HD(CP)2 numerical model evaluation and improvement. The main motivation for this is to provide easy access to data from the HD(CP)2 domain in unified formats from one server. HD(CP)2 data will be made available via the ICDC data center ( http://doi.org/10.17616/R39S3N ) in Hamburg.
- Cloudnet data created at the 3 AOs mentioned above shall be additionally stored in HD(CP)2 compliant file format under the following conditions only. o HD(CP)2-compliant files acknowledge the Cloudnet data origin explicitly in the header in an adequate way. o If Cloudnet data is locally reprocessed and sent to the Cloudnet server, the HD(CP)2 compliant Cloudnet files are also simultaneously recreated and linked with ICDC. o Download statistics of data containing Cloudnet products are created through ICDC once HD(CP)2-compliant Cloudnet files become available. These statistics will be regularly made available to the ACTRIS and HD(CP)2 SSCs to document the use of Cloudnet data.
- If the above conditions are met during the first phase of HD(CP)2, the HD(CP)2-compliant Cloudnet files may be produced for other AOs in the HD(CP)2 domain. This is subject to the agreement of both ACTRIS and HD(CP)2 SSCs. 6. In the future, ACTRIS and HD(CP)2 agree on an effort towards a unified Cloudnet data portal of all European AOs, strongly linked to the activities already on-going with the US partners from ARM/DOE.
