Platform for Regional Integrated Modeling and Analysis (PRIMA)

PNNL’s Platform for Regional Integrated Modeling and Analysis, or PRIMA, initiative (2010-2014, also known as the integrated Regional Earth System Modeling or IRESM initiative) was an effort to bring together models of climate, socioeconomics, hydrology, agriculture, buildings, electricity, and other sectors to simulate the complex interactions at the climate-energy-water-land nexus at decision-relevant scales. The PRIMA framework (see figure below) emphasized flexible coupling between model components driven by stakeholder decision-support needs. PRIMA developed some of the foundational capabilities that are now being leveraged and extended through the IM3 SFA.
