operated in the area around TROPOS in Leipzig.This dataset contains liquid water content
calculated by using radar and lidar to identify the liquid cloud base
and top in each profile, using the model temperature and pressure to
calculate the adiabatic liquid water content in each cloud layer, and
then using dual-wavelength microwave radiometers to scale the liquid
water content values to yield the correct liquid water path. While
this simple partitioning with height is somewhat uncertain, liquid
water clouds are frequently thin, occupying only a few vertical model
levels, so this dataset is adequate for testing liquid water content
in models. The error variable is determined as follows:
lwc_error=10*log[ (X+dX)/X ] with X being the measured value and dX
being the absolute uncertainty."noneThis 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*.51.35312.4341172none51.3513812.40138nonenonenone51.35312.4341172none51.35312.4341172noneLong term observationsLocal observationsVariable groupsCloud propertiesLong term observationsLocal observationsInstrument groupsLidarLong term observationsLocal observationsSupersitesLACROS2006Ewan O'ConnorLevel 2a Cloudnet product: Liquid water content (linear scaled
