Global Attributes:	Title: Cloud liquid water content profile from the Integrated Profiling Technique (IPT) Institution: Deutscher Wetterdienst, Meteorologisches Observatorium Lindenberg / Richard-Assmann-Observatorium Contact_person: Eileen Päschke, Eileen.Päschke@dwd.de Source: The IPT is based on MWR brightness temperatures, cloud radar reflectivity factor, Cloudnet categorization and prior information on temperature, absolute humidity, cloud liquid water and effective radius. The occurrence and vertical location of liquid clouds are obtained from the cloudnet target categorization product. The corresponding cloud radar reflectivities are read in from the Cloudnet categorization data product and thus are already corrected for gaseous and liquid attenuation. For more information see IPT handbook. History: Data processed with IPT 5.0 by University of Cologne Dependencies: external Conventions: CF-1.6 where applicable Processing_date: 2016-03-22, 07:35:55 (UTC) Author: Eileen Päschke, Eileen.Päschke@dwd.de Comments: Please see also IPT handbook for data interpretation.

	cllw: Array of 32 bit Reals [time = 0..2879][height = 0..494] time: height: standard_name: mass_concentration_of_cloud_liquid_water_in_air units: kg m-3 _FillValue: -999.0 comment: This variable is the cloud liquid water profile retrieved from the Integrated Profiling Technique, which combines MWR and cloud radar measurements with prior information in a 1D-Var retrieval approach. See also IPT handbook for more details.
	cllw_error: Array of 32 bit Reals [time = 0..2879][height = 0..494] time: height: long_name: error of mass concentration of cloud liquid water in air units: kg m-3 _FillValue: -999.0 comment: This variable is the posterior retrieval error and based on the assumed (random) uncertainties in the measurements, forward model and a priori information. See also IPT handbook for more details.
	retrieval_flag: Array of 16 bit Integers [time = 0..2879] time: long_name: retrieval flag units: 1 flag_masks: 0S, 1S, 2S _FillValue: 4 definition: 0:Retrieval converged, 1:Retrieval converged but probably unreliable, 2:No convergence comment: This variable describes whether a retrieval was performed for each time step and its associated quality. A fill value 4 means that no retrieval has been performed due to missing instrument data or inappropriate atmospheric conditions (coexistence of cloud liquid and drizzle/rain/ice). The most reliable value is when the rterieval converged and the measurements can be reproduced within the assumed uncertainties indicated by the value 0. A value of 1 indicates that the retrieval probably spuriously converged since the measurements can not be reproduced within the assumed uncertainties. A value 2 indicates that the retrieval did not converge to a solution.
