             abstract = "The present paper is a preliminary study preparing the 
                         introduction of reversible trace gas uptake by ice particles into 
                         a 3-D cloud resolving model. For this a 3-D simulation of a 
                         tropical deep convection cloud was run with the BRAMS cloud 
                         resolving model using a two-moment bulk microphysical 
                         parameterization. Trajectories within the convective clouds were 
                         computed from these simulation outputs along which the variations 
                         of the pristine ice, snow and aggregate mixing ratios and 
                         concentrations were extracted. The reversible uptake of 11 trace 
                         gases by ice was examined assuming applicability of Langmuir 
                         isotherms using recently evaluated (IUPAC) laboratory data. The 
                         results show that ice uptake is only significant for HNO3, HCl, 
                         CH3COOH and HCOOH. For H2O2, using new results for the partition 
                         coefficient results in significant partitioning to the ice phase 
                         for this trace gas also. It was also shown that the uptake is 
                         largely dependent on the temperature for some species. The 
                         adsorption saturation at the ice surface for large gas mixing 
                         ratios is generally not a limiting factor except for HNO3 and HCl 
                         for gas mixing ratio greater than 1 ppbv. For HNO3, results were 
                         also obtained using a trapping theory, resulting in a similar 
                         order of magnitude of uptake, although the two approaches are 
                         based on different assumptions. The results were compared to those 
                         obtained using a BRAMS cloud simulation based on a single-moment 
                         microphysical scheme instead of the two moment scheme. We found 
                         similar results with a slightly more important uptake when using 
                         the singlemoment scheme which is related to slightly higher ice 
                         mixing ratios in this simulation. The way to introduce these 
                         results in the 3-D cloud model is discussed.",
