DESCRIPTION:Prof. Chung-Chi Lin\, European Space Agency\nBio: Chung-Chi Li
 n was born on 8 Nov. 1952 in Kokura City\, Japan.  He obtained the Diplom
 a degree in 1979 from the EPF-Lausanne\, the M.S. and Ph.D. degrees from t
 he University of California\, Berkeley in 1982 and 1985\, respectively\, a
 ll in Electrical Engineering.  From 1979 to 1980\, he was a scientific co
 llaborator at the High Voltage Laboratory of the EPF-L.  From 1980 to 198
 5\, he was a Research Assistant at the Electronics Research Laboratory of 
 the Univ. of California\, Berkeley.  From 1985 to 1993\, he worked at Dor
 nier System (currently Airbus Defence and Space GmbH) in Friedrichshafen\,
  Germany.  In 1993\, he joined the European Space Technology Centre of ES
 A in Noordwijk\, the Netherlands.  His area of responsibility is developm
 ent of microwave payloads for future Earth Observation missions.  Since 2
 000\, he is the Head of Microwave Instruments Section in the Earth Observa
 tion Projects dept.  Lately\, he was the Guest Editor of the Special Issu
 e of the Proc. IEEE on Solar System Radar & Radio Science (May 2011).\nEUM
 ETSAT and ESA are running development activities for the Low-Earth-Orbit (
 LEO) meteorological satellite system that will ensure continuity of the cu
 rrent EPS/MetOp system around 2020 for the numerical weather prediction ap
 plications. As in the current system\, the new EUMETSAT EPS-Second-Generat
 ion (EPS-SG) system will be implemented with a space segment (MetOp-Second
 -Generation or MetOp-SG) developed by ESA through a prime contract awarded
  to Airbus Defence & Space\, France. The space segment of the EPS-SG missi
 on will consist of a constellation of two satellites (Sat-A and Sat-B)\, w
 ith ESA-developed instruments on Sat-A (the MicroWave Sounder -MWS-\, the 
 Multi-view Multi-polarisation\, Multi-channel Imager -3MI- and the Radio O
 ccultation instrument –RO-) and Sat-B (the Wind SCAtterometer -SCA-\, th
 e MicroWave Imager –MWI-\, the Ice Cloud Imager –ICI- and the second R
 O instrument).\nThe Microwave Sounder instrument (MWS)\, a passive radiome
 ter with 24 channels from 23.8 to 229 GHz\, will provide temperature and w
 ater vapour profiles in clear and cloudy atmosphere\, and cloud liquid wat
 er columns. It will complement the clear sky observations provided by the 
 Infrared Atmospheric Sounder instrument\, which will be contributed by the
  French Space Agency. MWS will have better spatial resolution and more obs
 ervation channels than its predecessor\, the AMSU-A and MHS suite of instr
 uments on board MetOp.\nThe Wind Scatterometer instrument\, a radar operat
 ing at C-band (5.3 GHz)\, will provide ocean vector wind observations with
  a better spatial resolution (≤ 25 km) and higher radiometric stability 
 (0.1 dB) than its predecessor instrument ASCAT on board MetOp. Moreover\, 
 the use of cross-polarisation (VH) on the Mid-beams\, in addition to the v
 ertical polarisation (VV) of ASCAT\, will significantly extend the upper d
 ynamic range of the wind measurements (up to 50 m/s) and will improve the 
 quality of the soil moisture product over land. There has been no well-cha
 racterised geophysical model function (GMF) which relates the cross-polari
 sed radar backscatter to the ocean surface vector wind. Thus\, as a part o
 f the MetOp-SG scatterometry mission\, airborne measurement campaigns unde
 r extreme wind conditions are undertaken in cooperation with NOAA.\nThe Mi
 crowave Imager (MWI) instrument\, a new passive radiometer with 26 channel
 s from 18.7 to 183 GHz\, will provide cloud and precipitation observations
  as well as water vapour and temperature gross profiles of the atmosphere.
  For surface observations\, it will provide sea ice\, snow and ocean surfa
 ce wind products. In particular\, its high frequency channels (118 – 183
  GHz) are optimised for observations of light precipitation and snow falls
  for higher latitudes.\nThe Ice Cloud Imager (ICI) instrument\, a new pass
 ive millimetre and sub-millimetre radiometer with 13 channels from 183 to 
 664 GHz\, will provide ice cloud and water vapour products at 15 km spatia
 l resolution. The channel overlap between MWI and ICI at 183 GHz is intend
 ed for cross-calibration between them. Since observations at ICI frequenci
 es have no precedence in satellite meteorology\, extensive airborne campai
 gns are undertaken for validating radiative transfer models and for develo
 ping retrieval algorithms. UK Met Office’s FAAM aircraft carries the ISM
 AR instrument (Int’l Sub-Millimetre Airborne Radiometer)\, jointly devel
 oped by the Met Office and ESA.\nThe presentation will address the overall
  system description\, the major microwave instruments as described above a
 nd their associated key technology developments.
