This grant supports a small workshop to plan collaborative research to develop moist physics parameterizations for the Community Atmosphere Model (CAM). The workshop (WS) is intended to advance the representation of cloud distribution and microphysics in the CAM by integrating efforts of members of the community with those of NCAR scientists. The goal is to improve capability to represent important microphysical processes and connections between clouds, chemistry and aerosols in the modeled atmosphere. The current formulation of cloud distributions and microphysics in the CAM is overly simplistic in representing these processes and interactions.The WS will "jump start" the process. A group of 10 members of the community with expertise in microphysical schemes will be invited to join NCAR scientists. All Community Climate System Model (CCSM) Atmospheric Model WG members (a self-appointed group) will be invited to attend, but funding will be limited to to the ~10 invited key participants. The PIs will develop a specific strategy for implementing a plan for the next version of CAM and CCSM, including roles, decisions, which processes and which representations they might use in order to insure that community development proceeds towards a common version of cloud fraction, microphysics and aerosol schemes for the CAM. The ultimate result of this process will be a new microphysics scheme or several candidate schemes for the next generation of CAM. Broader impacts include the benefits to be derived by over one hundred scientists who use the CCSM/CAM, and the potential for improved climate projections, so important to societal issues.

该补助金支持一个小型研讨会，计划合作研究，为社区大气模型（CAM）开发潮湿物理参数化。 研讨会（WS）的目的是通过将社区成员的努力与NCAR科学家的努力相结合，促进CAM中云分布和微观物理学的代表性。 目标是提高模拟大气中云、化学和气溶胶之间重要微物理过程和联系的能力。 目前CAM中云分布和微物理的公式在表示这些过程和相互作用方面过于简单。WS将“跳跃启动”这个过程。 将邀请10名具有微物理方案专业知识的社区成员加入NCAR科学家。 所有社区气候系统模型（CCSM）大气模型工作组成员（一个自我任命的小组）将被邀请参加，但资金将限于10名受邀的主要参与者。 PI将制定一个具体的战略，以实施下一版CAM和CCSM的计划，包括角色，决策，他们可能使用的过程和表示，以确保社区发展朝着CAM的云分数，微物理学和气溶胶方案的共同版本前进。 这个过程的最终结果将是一个新的微观物理方案或几个候选方案的下一代CAM。 更广泛的影响包括一百多名使用CCSM/CAM的科学家将获得的好处，以及改善气候预测的潜力，这对社会问题非常重要。
