Subvisible cirrus (SVC) clouds are often observed within the tropical tropopause layer (TTL) and have been shown to have a significant impact on the earth radiation budget. The Costa Rica Aura Validation Experiment (CR-AVE) sponsored by the National Aeronautics and Space Administration (NASA) took place near San Jose, Costa Rica 15 an influence on particle shape and the development of the large particles. A companion paper (Jensen et al., 2007) presents crystal growth calculations that suggest
