  • Abstract. To improve our understanding of how snow properties influence sea; ice thickness retrievals from presently operational and upcoming satellite; radar altimeter missions, as well as to investigate the potential for; combining dual frequencies to simultaneously map snow depth and sea ice; thickness, a new, surface-based, fully polarimetric Ku- and Ka-band radar; (KuKa radar) was built and deployed during the 2019–2020 year-long MOSAiC; international Arctic drift expedition. This instrument, built to operate; both as an altimeter (stare mode) and as a scatterometer (scan mode),; provided the first in situ Ku- and Ka-band dual-frequency radar observations from; autumn freeze-up through midwinter and covering newly formed ice in leads and; first-year and second-year ice floes. Data gathered in the altimeter mode; will be used to investigate the potential for estimating snow depth as the; difference between dominant radar scattering horizons in the Ka- and Ku-band; data. In the scatterometer mode, the Ku- and Ka-band radars operated under a; wide range of azimuth and incidence angles, continuously assessing; changes in the polarimetric radar backscatter and derived polarimetric; parameters, as snow properties varied under varying atmospheric conditions.; These observations allow for characterizing radar backscatter responses to; changes in atmospheric and surface geophysical conditions. In this paper, we; describe the KuKa radar, illustrate examples of its data and; demonstrate their potential for these investigations.;
