The scope of the project is the update of the TROPOGAS - DOAS system installed on the roof of ISAC-CNR in Bologna to foster its inclusion into the FRM4DOAS validation network. The project is composed of two phases. In phase A we will update the measurement configuration following as much as possible the FRM4DOAS requirements and perform a measurement campaign in Bologna. NO2 retrieved products will be compared with TROPOMI and synergy with in situ sensors will be exploited. In phase B an inter-calibration campaign will take place at BAQUNIN premises in Rome. The inter-comparison will be performed using Pandora 2S and Brewer spectrometers.

The air-snow interface is a critical layer that controls several processes and for this reason a deeper knowledge about driving parameters is the primary objective of this project. This goal will be approached at the Italian-French research facility at Dome-C combining different methodologies based on ground observations, proximal sensing, remote sensing and snow radiative modelling. The complexity of interconnected exchanges at the air-snow interface will be investigated considering the radiative transfer and photochemistry occurring at the surface. Both processes are strongly affected by the available snow surface area that is described by the roughness at a micro- and macro- scales. Activities will be focused on integrating already-operating observations at fixed position with spatial measurements about microphysical features of the snowed surface, the superficial roughness, the spectral/broadband albedo and the chemistry of the different involved matrices. The definition of the spatial and temporal variability of the snow cover, coupled to the detailed description available from long time-series at fixed positions, will contribute to assess the impact of different snow cover types on radiative and chemical exchanges at the air-snow interface and to support the validation of satellite snow-products. Furthermore, the field activities will be supported by a preparatory work operated in Italy that will be focused on the
technological development, on the standardization of measurements and the analyses of the acquired observations. While radiative measurements at the ground will be performed spatially distributed, simultaneous measurements of some photochemically active species (nitrogen and volatile organic compounds) in snow and air and their relative atmospheric fluxes will be also conducted. The final goal of the project will consists in integrating available datasets with novel measurements for obtaining a ground-truth reliable in terms of spatial variability.
