Cloud feedbacks and precipitation systems remain the primary source of uncertainty in Earth climate models and numerical weather predictions.??To enhance our understanding, there is a crucial need to comprehensively characterize the vertical structure of clouds and precipitation. This involves observing the microphysical, dynamical, and radiative processes occurring at cloud scales.
A solution to provide such observations involves leveraging measurements from multi-frequency radars spanning frequencies from 10 GHz to above 200 GHz. Using multiple frequencies facilitates the characterization of a broad spectrum of particles, from heavy precipitation tosmall ice crystals. Notably, the inclusion of G-band, operating at 1.5 mm wavelength (i.e. about 200 GHz), offers significant advantages in three key areas: boundary layer clouds, cirrus and mid-level ice clouds, and precipitating snow.? Recent technology advancements in millimetre-wave technology (such as RF mixer, high power transmitters, etc.) have enabled the development of G-band radars.
Successful investigations with ground-based radar (UK-CEOI funded GRACE experiment) and airborne radar (US NASA JPL Vapor In-cloudProfiling Radar (VIPR) experiment) have validated the potential of G-band radar for cloud and precipitation research. Following thesesuccessful experiments, ESA has initiated an instrument system study (On-going contract no: 4000139352) to explore the possible instrument implementation of a G-band spaceborne radar for 2 different ESA mission categories, a micro-satellite platform (Scout like mission) and a high reliability large platform (Earth Explorer like mission), to identify the technological gaps and to define the associated technology roadmap.?The proposed activity aims at developing a representative airborne cloud radar instrument demonstrator to validate the benefits of the addition of G-band radar measurement for Earth observation.?Read more
