A Simple Model for Understanding the DIM Dust Measurement at Comet   67P/Churyumov-Gerasimenko
  We present a simple model for gas and dust flow from 67P/Churyumov-Gerasimenko that can be used to understand the grain impact observed by the DIM instrument on Philae (Krueger et al. 2015) We show how model results when applied to the GIADA measurements (Rotundi et al. 2015; Della Corte et al. 2015) can be used, in conjunction with the results found by the MIRO (Schloerb et al. 2015) and VIRTIS (De Sanctis et al. 2015) instruments to infer surface properties such as surface temperature and surface ice fraction.
