An International Network of Ground-based Microwave Radiometers for the Assimilation of Temperature and Humidity Profiles into Nwp Models

Combining Data from Ground-based Microwave Radiometers and Other Instruments in Temperature and Humidity Profile Retrievals

Ground-based microwave radiometry offers a new opportunity to automate upper air observations by providing information on temperature and humidity profiles as well as the integrated water vapour and liquid water amounts with high time resolution. To improve their relatively poor vertical resolution and provide a more complete picture of the vertical profile, radiometer observations can be combi...

Comparison of brightness temperatures observed from ground-based microwave radiometers during TUC

The agreement of two ground-based microwave radiometers during the Temperature, hUmidity, and Cloud (TUC) profiling campaign has been evaluated in terms of measured brightness temperature. To account effectively the instruments’ specifications, we discuss and estimate an equivalent monochromatic frequency, which significantly reduces the bias introduced by ideal monochromatic modelling. The eff...

Accuracy assessment of an integrated profiling technique for operationally deriving profiles of temperature, humidity, and cloud liquid water

[1] An integrated profiling technique (IPT) for the simultaneous retrieval of the atmospheric state parameters temperature, humidity, and liquid water content profiles is assessed. The method combines measurements of a modern, ground-based profiling station equipped with a microwave profiler, cloud radar, and ceilometer, with the closest operational radiosonde measurement and standard surface-b...

Temperature and humidity profile retrievals from ground-based microwave radiometers during TUC

Thermodynamic atmospheric profiles have been retrieved from ground-based microwave radiometers during the Temperature, hUmidity, and Cloud (TUC) profiling campaign. A variety of inversion methods is presented, in terms of requirements, advantages, and limitations. Results confirm the theoretical expectation that retrievals’ accuracy and resolution degrade steadily with height up to 3 km, then m...
