Automated Algorithm for MFRSR Data Analysis

We present a substantial upgrade of our previously developed multi-filter rotating shadowband (MFRSR) data analysis algorithm (Alexandrov et al. 2002). For the new version an automated cloud screening procedure (Alexandrov et al. 2004) has been designed and a bimodal aerosol particle size distribution model is used defined by a variable fine mode size and a ratio between the fine and coarse modes.
