The Global Analysis, Integration and Modelling Task Force (GAIM) is a component of the International Geosphere Biosphere Program (IGBP) of the International Council of Scientific Unions (ICSU). The GAIM Task Force Office is located in the Institute for the Study of Earth, Oceans, and Space, University of New Hampshire.

The goal of GAIM is to advance the study of the coupled dynamics of the Earth system using as tools both data and models. GAIM emphasizes activities designed to expand upon the development, testing, and analysis of integrative data sets and models of those aspects of the Earth system where IGBP has the scientific lead, and it commits to collaborate on aspects of the Earth system where WCRP and IHDP have the lead.

The role of GAIM is multi-fold. The Task Force must analyze current models and data, assess the capability of current models and experimental programs to resolve key questions, and advance and synthesize our understanding of the global biogeochemical cycles and their links to the hydrologic cycle and to the physical-climate system as a whole. This is done both for natural systems and variability as well as in the context of anthropogenic perturbations. The challenge to GAIM is to initiate activities that will lead to the rapid development and application of a suite of Earth system models spanning a range of model complexity that integrate the roles and interactions of physical climate, ecological, and human systems.
