A Proposal to Develop an NCAR Ice Initiative
Overview
Ice initiation processes in clouds are poorly understood. This results in large uncertainties in modeling the production of precipitation and predicting climate changes. Recent advances in observational tools, laboratory cloud simulation chambers, numerical models, and computer hardware provide new capabilities to understand and model ice initiation processes. The goal of this activity is to develop an NCAR strategic initiative , with considerable input from the university community including graduate students, to advance the understanding and modeling of ice initiation in clouds.
In 2003, Heymsfield, Rogers and Stith received one year's funding from the NCAR Opportunity Fund to pursue this work. More detail is in the Opportunity Fund Proposal (or Summary only). As part of the first year's activities, a steering committee was formed, and plans were developed to pursue collaborative research in this area, as described on this web page.
