  author={Ed R. Westwater and Susanne Crewell and Christian M{\"a}tzler and Domenico Cimini},
Surface-based radiometric measurements of tropospheric parameters have long provided useful measurements of temperature, water vapor, and cloud liquid. In this paper, a general overview of physical fundamentals, measurement techniques, and retrieval methodology is given. Then several contemporary instruments are discussed and representative results are presented. Recent and promising developments include multifrequency radiometers, scanning observations of clouds, and combined activepassive… 
Refined Physical Retrieval of Integrated Water Vapor and Cloud Liquid for Microwave Radiometer Data
The original algorithm was replaced by a new statistical retrieval based on the simulations of TROWARA data using radiosonde profiles, and the cause of the variable ILW bias has been identified and a method for its reduction to the level of 0.001 to 0.005 mm has been developed and tested.
