Far Infrared Radiative Closure Experiment For Antarctic Clouds – FIRCLOUDS – Lidar backscattering/depolarization data

The required spectral radiance measurements in the range 100-1000 cm-1 are acquired by the Fourier spectroradiometer REFIR-PAD, which is operative in continuous and unattended mode at Dome-C, whereas the atmospheric cloud fields are constrained with the support of a backscattering/depolarization lidar, for the estimation of the clouds position, phase, and the extinction profile, an ice and halo imager cameras, for the assessment of the cloud ice crystals micro-physics, and a micro rain radar (MRR) for the determination of the clouds reflectivity and the vertical velocity of ice crystals in the cases of precipitating clouds.
