The specific CLOUDNET products used for the retrieval are the target categorization product and the cloud radar reflectivities corrected for gaseous and liquid attenuation. Essen radiosonde climatology provides prior information on temperature and absolute humidity. Retrieval is based on optimum estimation theory and must not be interpreted as an explicit solution, but as the most probable solution of a Gaussian distributed probability density function. none RPG Microwave Radiometer HATPRO, Generation 2 50.908547 6.413536 111 none 14 channel K and V band microwave profiler, fully scanable in azimuth and elevation CLOUDNET categorization products none none none none Please see the XML meta data files for the synergy "cloudnet products" in the HD(CP)^2 Observation data Archive.

paper

2008 U. Loehnert et al. This paper describes advances in ground-based thermodynamic profiling of the lower troposphere through sensor synergy. The documented integrated profiling technique (IPT), which uses a microwave profiler, a cloud radar, and a ceilometer to simultaneously retrieve vertical profiles of temperature, humidity, and liquid water content (LWC) of nonprecipitating clouds, is further developed toward an enhanced performance in the boundary layer and lower troposphere. For a more accurate temperature profile, this is accomplished by including an elevation scanning measurement modus of the microwave profiler. Height-dependent RMS accuracies of temperature (humidity) ranging from ∼0.3 to 0.9 K (0.5–0.8 g m−3) in the boundary layer are derived from retrieval simulations and confirmed experimentally with measurements at distinct heights taken during the 2005 International Lindenberg Campaign for Assessment of Humidity and Cloud Profiling Systems and its Impact on High-Resolution Modeling (LAUNCH) [...] Journal of Atmospheric and Oceanic Technology, vol. 25, pp. 1251–1266
