This file includes the ice water content derived with the iwc-Z-T method of Hogan et al., 2006 (see references), including the error and bias. A separate iwc data set is stored that contains iwc for profiles where attenuation by rain or liquid water occurred below an iwc data point. This dataset is subject to larger uncertainties due to wrong attenuation correction. The classificiation of ice pixels is based on the cloudnet target categorization.
Limitations: none
Provenance: Cloudnet-processed remote-sensing data. See the global argument *cloudnet_source* for more details.
