This report presents an analysis of the atmospheric characteristics in the terahertz spectral region (frequencies from 300 GHz to 10 THz, wavelengths from 30 μm to 1 mm), with particular attention in the range 1 to 5 THz. This interval is the spectral range of interest in the framework of DIAST project. Historically the THz spectral interval has been characterized by a relative lack of convenient radiation sources, detectors and transmission technology. This document considers the designs of different spectroradiometers and the simulation of their instrumental responses. The simulations take into account the scenarios presented in the document: “REPORT - DIAST Project 1 - Typical atmospheric scenarios in the 0.6 - 5 THz wavelength range”, in which the atmospheres have been chosen to be representative of a realistic working scenario in different acquisition geometries, taking into account the typical gaseous components and pollutants of terrestrial atmosphere.
