Dome A

DOME-A is one of several summits or 'domes' of the Antarctic Ice Sheet at 4093m above sea level.

The following plot shows the transmission of the first decile (10 %, grey) and the three quartiles (25 % red, 50 % blue, 75 % green) of the pwv statistics between 2008 and 2010 extracted from the IASI satellite. 

The left plot shows curves for pwv=0.1mm (grey), 0.2mm (red), and 0.3mm (blue). The right plot shows the transmission in the high-frequency range around the ionized carbon line [CII} at 1.9 THz (158 micron) for DOME-C and DOME-A. All models were calculated for Antarctic winter conditions (temperature and pressure profiles from july).
