Global Attributes:	Title: Microwave radiometer retrieved prw Institution: Research Center Juelich Institute for Energy and Climate Research IEK8 Contact_person: Ulrich Loehnert (loehnert@meteo.uni-koeln.de) Source: RPG HATPRO G2 microwave radiometer TOPHAT History: Data processed with mwrpro-v04 by University of Cologne; Retrieval version: deb_rt00 Dependencies: sups_joy_mwr00_l1_tb_v01 Conventions: CF-1.6 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. Processing_date: Sat Jul 18 06:13:48 2015 Measurement_site: JOYCE Juelich Observatory for Cloud Evolution Author: Ulrich Loehnert (loehnert@meteo.uni-koeln.de) Comment: prw errors are given as a function of retrieval elevation angle. Note, observations may occur at different angles (interpolation).

In cases of doubt, please refer to the contact person. A Fillvalue of 0 means that data has not been flagged. Bands refer to the measurement ranges (if applicable) of the microwave radiometer; i.e band 1: 20-30 GHz, band 2: 50-60 GHz, band 3: 90 GHz; tb valid range: [ 2.70, 330.00] in K; prw valid range: [ 0., 100.] in kgm-2; clwvi (zeroing not applied) valid range: [-0.2, 3.0] in kgm-2;
