613 Seminar: Pavlos Kollias

School of Marine and Atmospheric Sciences, Stony Brook University (SUNY)

The Earth Clouds, Aerosol and Radiation Explorer (EarthCARE) satellite is a joint mission by the European Space and Japanese Aerospace Exploration Agencies scheduled for launch in early 2019 and features the first atmospheric Cloud Profiling Radar (CPR) with Doppler capability in space. The seminar describes the capabilities of the nadir pointing 94-GHz radar and discusses in detail the challenges in performing Doppler velocity measurements from a satellite. The CPR L2a data products that are currently in the final stage of development will be described. Emphasis will be given to the algorithms designed for removing biases and reducing uncertainty in the CPR Doppler velocity measurements. The areas where the CPR Doppler velocity measurements are expected to improve our current understanding of cloud and precipitation dynamics and microphysics will be discussed. Finally, the seminar will briefly discuss remaining gaps in spaceborne radar measurements.
