The PIs describe a program of theoretical work on processes occurring on the surfaces of small ice particles in the atmosphere. The plan is to adapt existing models of crystal growth with and without impurities to the cases of atmospheric interest. Focus will be on the effects of foreign gases and impurities, surface heating and surface melting on the growth and evaporation rates of ice particles. The work will be carried out in close cooperation with two groups engaged in relevant laboratory experiments and one group making field measurements, and will build on theoretical work already underway in the PI's group.

pi描述了在大气中小冰粒表面发生的过程的理论工作程序。该计划是将现有的有杂质和不含杂质的晶体生长模型调整到对大气感兴趣的情况。重点将放在外来气体和杂质、表面加热和表面融化对冰粒生长和蒸发速率的影响上。这项工作将与两个从事相关实验室实验的小组和一个进行实地测量的小组密切合作，并将以PI小组已经进行的理论工作为基础。
