Abstract
Ground-based cosmological observations need a detailed knowledge about atmospheric transmission. A continuous monitoring of the transmission in the FIR/mm wavelength range is needed mainly due to H2O high frequency variations along the line of sight of a telescope. CASPER 2 (Concordia Atmospheric Spectroscopy of Emitted Radiation) is a spectrometer devoted to measurements of atmospheric emission in the millimetric region (4-12 cm -1, 120-360 GHz) with a spectral resolution of 0.2 cm-1. The instrument allows a continuous monitoring of the atmospheric transmission of the same sky region explored with MITO (Millimeter and Infrared Testagrigia Observatory, 3480 m asl, Italy) telescope, during cosmological observations. © 2010 EAS, EDP Sciences.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
