Abstract

Atmospheric transmission from Dome A, Antarctica, presents new possibilities in the field of terahertz astronomy, where space telescopes have been the only observational tools until now. Using atmospheric transmission measurements at Dome A with a Fourier transform spectrometer, transmission spectra and their stabilities have been analyzed, which show that important atmospheric windows for terahertz astronomy open for a reasonable length of time in winter season. With large aperture terahertz telescopes and interferometers at Dome A, high angular resolution terahertz observation is foreseen for atomic lines from ionized gas and exoplanet research.
