| Zusammenfassung |
| The HAMSTRAD (H2O Antarctica Microwave Stratospheric and Tropospheric Radiometers)
microwave instrument operating at 60 and 183 GHz and measuring temperature and water
vapor, respectively from 0 to 10 km altitude with a time resolution of 7 minutes has been
successfully deployed at Dome C (Concordia Station), Antarctica (DC, 75Ë 06’S,
123Ë 21’E, 3233 m asml) during the first summertime campaign for 12 days in
January-February 2009. It is continuously and nominally running from January
2010 to date, after the second summertime campaign hosted within a dedicated
shelter. Measurements and internal calibration are automated, transfer of data are
performed on a daily and automated basis. External Liquid Nitrogen calibration is
performed twice per year. We have already used the very first sets of HAMSTRAD data
recorded when the instrument was outdoor and indoor to assess its potentiality
to sound the troposphere over DC, from the Planetary Boundary Layer (PBL) up
to the tropopause, via the free troposphere. We have compared the HAMSTRAD
measurements to several sets of measurements performed at the DC station or in its vicinity:
meteorological radiosondings (RS), in situ PT100 and Humicap sondes along a 45-m high
tower, meteorological sensor attached to the HAMSTRAD instrument, analyses
from the European Centre for Medium-Range Weather Forecasts (ECMWF) and
the spaceborne Infrared Atmospheric Sounding Interferometer (IASI) instrument. |
