We describe an instrument capable of accurate measurement of atmospheric transparency in the FIR (4 ≲ \̃gn ≲ 20 cm−1. We also discuss the possibility of obtaining quantitative information about the atmospheric water vapour profile by means of very accurate measurement of the atmospheric transparency spectrum. We also report as a preliminary result a spectrum of the atmospheric transparency and discuss the problem of the excess absorption in the atmospheric windows, comparing our data with models using different power law behaviours for the continuum term. We find that our data agree with a ν2 behaviour at the 50% confidence level.

Abstract
We describe an instrument capable of accurate measurement of atmospheric transparency in the FIR (4 ≲ \̃gn ≲ 20 cm−1. We also discuss the possibility of obtaining quantitative information about the atmospheric water vapour profile by means of very accurate measurement of the atmospheric transparency spectrum. We also report as a preliminary result a spectrum of the atmospheric transparency and discuss the problem of the excess absorption in the atmospheric windows, comparing our data with models using different power law behaviours for the continuum term. We find that our data agree with a ν2 behaviour at the 50% confidence level.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
