Abstract: The PRANA research programme foresees the monitoring and the spectral characterisation of the downwelling longwave radiation from 100 to 1400 cm-1 emitted by the atmosphere in different sky conditions. This measurement will allow to improve the knowledge in the under-explored far infrared (FIR) spectral region of the emission spectrum. In particular, the modelling of the pure rotational water vapour band and the radiative properties of high altitude ice clouds, such as cirrus and polar stratospheric clouds (PSC), will be s tudied in depth. As the modelling capabilities is validated, the measurement can be used for the estimation of the total precipitable water vapour content (PWV) and the PSC coverage.
