The DOCTOR project (2016-present)
The Dome C Tropospheric Observer (DOCTOR) project aims to exploit the specific
observation point provided by the East Antarctic Plateau to perform a
long-term monitoring of the Antarctic troposphere in terms of its radiative
and thermal properties and its composition.
The COMPASS project (2013-2015)
The CoMPASs (Concordia Multi-Process Atmospheric Studies) project
has been developed in order to identify and characterize these
feedbacks and interactions between processes, spanning across three
different atmospheric regions: the boundary layer, the troposphere and
CoMPASs makes use of a strong observational component, deploying an
array of different instruments all characterized by the vertical
remote sensing measurement technique: stratospheric and tropospheric
lidars, UV and middle/far-infrared spectroradiometers, and a
The PRANA project (2011-2013)
The PRANA (Proprieta' Radiative del vapore Acqueo e delle nubi in
Antartide - Radiative Properties of Atmospheric Water vapour and
clouds in Antarctica) research programme regards the monitoring and
the spectral characterisation of the downwelling longwave radiation
(DLR) from 100 to 1400 cm-1 emitted by the atmosphere in different sky
conditions. This measurement will allow to improve the knowledge in
the under-explored far infrared (FIR) spectral region of the emission
spectrum from 100 to 400 cm-1. In particular, the modelling of the pure
rotational water vapour band and the radiative properties of high
altitude ice clouds, such as cirrus and polar stratospheric clouds
(PSC), will be studied in depth. As the modelling capabilities is
validated, the measurement can be used for the estimation of the total
precipitable water vapour content (PWV) and the PSC coverage.
The STRAAP-B project (2014-2015)
The STRRAP-b (STudy of the Radiative Regimes over the Antarctic Plateau and beyond) project aims to deepen the knowledge on the Antarctic Plateau radiative regime and its regulating processes, through in situ radiometric measurements coupled with remote sensing techniques, using broadband and hyperspectral instrumentation.
Specifically, the project aims to define accurately the effects of cloud cover, ozone and water vapor, and surface reflectance properties on the radiative balance over the East antarctic Plateau. For the different conditions of cloud coverage, the downwelling and upwelling solar radiation will be spectrally and geometrically characterized.
Information provided by the BSRN station and new instrument implementations will be exploited to calibrate/validate satellite retrieval products related to the surface reflectivity, and provide validated measures of the components of solar and infrared irradiance incident and reflected by the surface. The use of satellite information properly configured over the Antarctic in conjunction with the data provided by the other three BSRN stations operated in Antarctica (SPO, SYO, GVN), will allow researchers to expand definitions of the radiative regimes to a regional scale and possibly up along the coast. Atmospheric corrections will be taken into account by ground based remote sensing of columnar ozone, measurements of UV spectral radiation, while water vapor will be measured by various platforms including radiosonde, REFIR-PAD IR radiometer and HAMSTRAD MW radiometer.
Past campaigns performed by REFIR-PAD (not involving Concordia Station)
Radiative Heating in the Underexplored Bands Campaign 2 - RHUBC2 (2009)
The second RHUBC campaign took place from August to October 2009 from the Cerro Toco site in the Chilean Andes (5383 m a.s.l.) under the U.S. ARM (Atmospheric Radiation Monitoring) program.
Earth COoling by WAter vapor Radiation - ECOWAR (2007)
The ECOWAR campaign took place from 3 to 16 of March, 2007 from the Testa Grigia scientific station near Plateau Rosa, at 3480 meters a.s.l. on the Italian-Swiss Alps. Here are some papers describing the ECOWAR campaign and the results obtained through it.
