The dataset contains daily nc-files of the Cloudnet ice particles effective radius during Polarstern cruise PS106 based on: - 35.5 GHz Cloud radar MIRA. The data is retrieved using the instrument synergystic approach Cloudnet (Illingworth, 2007 doi:10.1175/BAMS-88-6-883 ). This variable was calculated from visible extinction coefficient and ice water content using the following analytical formula: r_eff[\\mum] = 3*IWC[g cm-3] / (2 rho_i \\alpha[m-1]) 10**6 with rho_i=0.917g cm-3 the desity of solid ice. This retrieval is based on an analytical relationship between IWC and \\alpha. However both parameters have been retrieved following Hogan 2006 (doi:10.1175/JAM2340.1 ) by using two different empirical formulas based on the same measured quantity, the 35.5-GHz radar reflectivity factor.
