  1. HAMPThe Microwave Package on the upcomingHALO (high altitude and long range) research aircraft • Mario Mech1,2, Susanne Crewell1, • Gerhard Peters2, Lutz Hirsch2, • and Thomas Rose3 • 1 University of Cologne, Germany • 2 Max-Planck Institute Hamburg, Germany • 3 Radiometer Physics, Bonn, Germany

  2. What for? Using active and passive instruments in combination for a more comprehensive view on the cloud and precipitation structure Validation for GPM Use in conjunction with the other instruments operated on HALO ...

  3. High Altitude and LOnge - new aircraft of the German atmospheric science community buisiness jet GulfstreamG550 transformed into research platform for airborne atmospheric science and Earth observations 10000 km one way UTLS Oberpfaffenhofen

  4. HALO - Microwave Package basic instrumentation GOMAS CIWSIR

  5. frequency 36.5 GHz sensitivity -48 dBZ vert. res. 30 m along track res. 250/50 m across track res. 50 m variables Z,vdoppler,LDR Cloud Radar MIRA-36 provided by University of Hamburg

  6. removing atmospheric plankton (LDR, structure, T) preparative work for the cloud radar Hamburg 2007/05/13 (Bauer and Goersdorf, 2007)

  7. K V W F G Frequencies 22.24 50.30 90.0 118.75±8.5 183.31±12.5 23.04 51.76 118.75±4.2 183.31±7.5 23.84 52.8 118.75±2.3 183.31±4.5 25.44 53.75 118.75±1.4 183.31±3.5 26.24 183.31±2.5 27.84 183.31±1.5 31.40 183.31±0.6 FWHM 4.0° 3.5° 2.5° 2.5° 2.5° PMW radiometer specifications K,V G

  8. 1-D, plan-parallel RT model • spherical particles with frequency-dependent density/size modification (Staelin, 2008) • emissivity ([l] maps,[o] model) • CRM - Méso-NH • 5 hydrometeor categories - cloud, cloud ice, snow, graupel, rain simulated brightness temperatures Ocean Land

  9. simple retrieval by mutliple regression problems with smaller rain water path amounts

  10. Summary & Outlook cloud radar and selected microwave frequencies seems to have interesting information content cloud radar and passive microwave components are prepared - to be tested on ground late 2009 belly pod with MW components will be mounted on the aircraft 2010 first missions

  11. Thanks!
