Triple-Frequency Radar Retrievals

Abstract

With triple frequency radars becoming more and more popular both at ground-based facilities and on airborne platforms and with the prospect of a space mission with a triple-frequency radar payload on the horizon, triple-frequency radar retrievals are becoming fertile areas of active research. In this chapter the benefits and potentials of a triple-frequency radar approach for retrieving rain and ice microphysics will be discussed first on a theoretical basis and then demonstrated for a stratiform case study extracted from the OLYMPEX field campaign with Ku-Ka-W band radar observations. Challenges and recommendations for future work are included in the chapter.
