Dual-Wavelength Humidity Profiles Using S-PolKa During the DYNAMO Field Campaign

摘要: The NCAR scanning, S-and Ka-band dualwavelength, dual-polarimetric, radar (S-PolKa) makes simultaneous S-band and Ka-band measurements with 1○ beamwidth and nominal range resolution of 150 m. Both radars have dual-polarization and Doppler measurement capabilities. The S-PolKa radar is a national resource as part of the NSF Deployment Pool and has been deployed for atmospheric studies around the world. The dual-wavelength and dualpolarization capabilities of S-PolKa enable the estimation of humidity profiles in the lower troposphere (Ellis and Vivekanandan, 2010) and liquid water content (LWC). Using the LWC estimates and making some reasonable assumptions results in mass weighted diameter (D0) estimates (Ellis and Vivekanandan, 2011).
