Program for Climate Model Diagnosis and Intercomparison, Lawrence Livermore National Laboratory, U. S. Department of Energy
Data Center Description
The Program for Climate Model Diagnosis and Intercomparison (PCMDI) was established in 1989 at the Lawrence Livermore National Laboratory (LLNL) in the San Francisco Bay area. Our staff includes research scientists, computer scientists, and support personnel. There are several means of communicating with PCMDI.
PCMDI's principal mission is to develop improved methods and tools for the diagnosis,validation and intercomparison of global climate models (GCMs) (what we call a climate modeling infrastructure), and to engage in research on a wide variety of outstanding problems in climate modeling and analysis.
The need for standards in both modeling and analysis has become increasingly apparent as more complex models are developed, while the disagreement among models, and between models and observations, remains significant and poorly understood. The nature and causes of these disagreements must be accounted for in a systematic fashion before models can be confidently used for climate sensitivity and predictability studies in support of global change research.
