This program is dedicated to improving the science of integrated assessment by doing cutting edge research in critical areas of IAM development and integrating that research with a program of model inter-comparisons and IAM scenario ensemble construction activities. This program has been very closely linked to other climate change research programs in the U.S. and abroad which has helped to keep the work at the cutting edge of the field, responsive to the needs of the IAM community, highly transparent, accessible and credible. As anticipated, progress in the scientific research areas has informed the model comparison and scenario ensemble tasks, and the model comparison and scenario ensemble activities have helped set priorities for the research areas. We have continually and systematically broken each research area, as well as the model comparison and ensemble construction work, back down to fundamental first principals to help assess the state of the art and set focused priorities for the individual research efforts.

The first three years of the research program (August 2010 - July 2013) included work in three research focus areas: advancing progress on selected major scientific challenges in the field of integrated assessment; advancing methods and capabilities for inter-model testing and diagnostics; and enhancing capabilities for multi-model, "ensemble-like" analyses for improved insights in science studies and science-based analyses.

During this period the five research areas included in research focus area (1) were: science and technology, impacts and adaptation, regional integrated assessment modeling, key energy-related intersecting systems, and uncertainty.

As the PIAMDDI entered its second phase in August of 2013, it was recognized that the value of our research was not in only making progress on the initially identified research topics but also identifying future research needed to make further progress in these areas. Through our work in phase one of the research program, we identified three major focus areas for continued research: integrated climate change impacts assessment; integrated assessment model component emulation; and characterizing and representing uncertainty. Each of these focus areas requires parallel efforts in basic research, research coordination across research teams and communities, and its own model diagnostics and validation research activities. The essence of PIAMDDI is in organizing and executing these types of activities, each of which requires bringing researchers, research communities, and disciplines together in productive ways that improve the collective state-of-the-art of the whole integrated assessment modeling community.
