The objective of CMEP is to increase community-wide diagnostic research into the quality of model simulations, leading to more robust evaluations of model predictions and a better quantification of uncertainty in projections of future climate. The results of this research will be used for the subsequent evaluations of the quality of U.S. model global and regional climate projections of the 21st century and beyond in the context of an international multi-model dataset.
Analysis of Climate Model Simulations for the IPCC Fifth Assessment Report (CMEP 2011) - To promote diagnostic analysis of studies of late 19th - 20th century simulations through intercomparisons and comparisons with observations. The analysis of multiple models and ensembles is especially encouraged. Examinations of physical climate features and processes such as regional climate, climate variability and trends, modes of natural variability, hydrological cycle behavior, and extreme events are appropriate. In addition, we encourage analysis of initialized decadal hindcasts and predictions for predictability studies of the climate system on interannual to decadal time scales.
DRICOMP focused on evaluation of a variety of existing model products to address issues such as the roles of the oceans and the seasonal cycle in drought, the impacts of drought on water availability, and distinctions between drought and drying. The objective of DRICOMPs to increase community-wide diagnostic research into the physical mechanisms of drought and to evaluate its simulation in current models. DRICOMP will lead to more robust evaluations of model projections of drought risk and severity, and thus to a better quantification of the uncertainty in such projections.
