Dome C

DOME-C is one of several summits or 'domes' of the Antarctic Ice Sheet of at 3233 m (10 607 ft) above sea level. It is the site of the Concordia Research Station, jointly operated by France and Italy.

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 the transmission in percent for values of pwv=0.3mm (grey), 0.6mm (red), and 1mm (blue) against frequency/wavelength for a frequency range 0-2000 GHz. The frequency resolution is 200 MHz. The right plot shows curves for pwv=0.1mm (grey), 0.2mm (red), and 0.3mm (blue). All models were calculated for Antarctic winter conditions (temperature and pressure profiles from july).

0-2000 GHz

Zooms into some THz-windows at higher frequency resolution. All models are valid for pwv=0.2mm.

Zoom into the 200 micron (1400 GHz) window for a range of pwv=0.1 to 0.7mm. All models have a resolution of 200 MHz.

A larger frequency range of 0-10 THz (3mm to 30 micron) shows this plot for pwv=0.2mm. The frequency resolution is 200 MHz.
