“…The atmospheric conditions at Dome C are exceptionally cold, dry and rarefied as well as consistently low in fractional cloud coverage. The long distance from the coast (>1000km) implies a low atmospheric aerosol and water vapor content 26,27 . A permanent research station has been established and is operated jointly by the French Institut Polaire Francais Paul Emile Victor (IPEV) and the Italian Programma Nazionale Ricerche in Antartide (PNRA).…”

MODIS is a scanning radiometer that has 36 spectral bands with wavelengths from visible (VIS) to long-wave infrared (LWIR). Its observations and data products have significantly enabled studies of changes in the Earth system of land, oceans, and atmosphere. Currently, there are two nearly identical MODIS instruments operated in space: one on the Terra spacecraft launched in December 1999 and another on the Aqua spacecraft lunched in May 2002. MODIS reflective solar bands (RSB) are calibrated on-orbit by a system that consists of a solar diffuser (SD) and a solar diffuser stability monitor (SDSM) on a regular basis. Its thermal emissive bands (TEB) calibration is executed on a scan-by-scan basis using an on-board blackbody (BB). In addition to on-board calibrators (OBC), well-characterized ground targets have been used by MODIS calibration and validation scientists and by the MODIS Characterization Support Team (MCST) to evaluate and validate sensor on-orbit calibration, characterization, and performance. In this paper, we describe current MCST effort and progress made to examine sensor stability and inter-calibration consistency using observations over Dome Concordia, Antarctica. Results show that this site can provide useful calibration reference for a wide range of Earth-observing sensors.

“…Dome C is an area where observation and modelling of the boundary layer have already been performed due to its particular location (Swain and Gallée, 2006;Sadibekova et al, 2006;King et al, 2006;Gallée and Gorodetskaya, 2010;Genthon et al, 2010Genthon et al, , 2013Brun et al, 2011;Lascaux et al, 2011;Argentini et al, 2013;Pietroni et al, 2014). Furthermore, Dome C was recently selected as the test site for the next Gewex Atmospheric Boundary Layer Studies (GABLS4) model intercomparison (see http://www.…”

“…The good management of logistics between the Concordia station and the Antarctic coast (Terre Adélie) and the low optical turbulence at Dome C also promoted the site for astronomical observations (see e.g. Swain and Gallée, 2006;Sadibekova et al, 2006). The main characteristic of meteorological conditions at Dome C is that turbulent conditions in the nearsurface atmosphere are only effective in a rather shallow layer, especially during night-time .…”

Abstract. Regional climate model MAR (Modèle Atmosphérique Régional) was run for the region of Dome C located on the East Antarctic plateau, during Antarctic summer 2011-2012, in order to refine our understanding of meteorological conditions during the OPALE tropospheric chemistry campaign. A very high vertical resolution is set up in the lower troposphere, with a grid spacing of roughly 2 m. Model output is compared with temperatures and winds observed near the surface and from a 45 m high tower as well as sodar and radiation data. MAR is generally in very good agreement with the observations, but sometimes underestimates cloud formation, leading to an underestimation of the simulated downward long-wave radiation. Absorbed short-wave radiation may also be slightly overestimated due to an underestimation of the snow albedo, and this influences the surface energy budget and atmospheric turbulence. Nevertheless, the model provides sufficiently reliable information about surface turbulent fluxes, vertical profiles of vertical diffusion coefficients and boundary layer height when discussing the representativeness of chemical measurements made nearby the ground surface during field campaigns conducted at Concordia station located at Dome C (3233 m above sea level).

Abstract. Currently, there are two nearly identical moderate resolution imaging opoctrnmJiometer (MK}DlS) instruments operated in space: one on the Tuoo spacecraft |uuuc6cd in December 1999 and another oil the Aqua spacecraft launched in May 2002. MDDIS has 36 upcoto| bands with ~vovu|wogtbu covering from visible (\/l8) to long-wave infrared (LTYLD).
