Observational challenges in evaluating climate models

Description: 

1. Investigate process responsible for present day mean, variability and change in South Asia precipitation and test the ability of state-of-the-art climate models to simulate this. 2. Evaluate the skill of initialized experiments in predicting South Asia precipitation variability and investigate mechanisms for predictability. We find that the model spread is comparable to the spread in different observational data products making any definitive conclusions about model fidelity difficult. We raise the possibility that the principal barrier to model improvement a lack of accurate observations rather than model resolution and parameterization of physical processes.
