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.?
