Modular ocean model (MOM) is a standard global ocean circulation model used by many researchers in the world. The origin of this model can be traced back to the community code originally developed by Kirk Bryan and Mike Cox in the 1960s, and many other global ocean models can be traced back to their origins. In the early 1990s, Ron pacanowski, Keith Dixon, and Tony Rosati redesigned the old code into a more modern format, while Steve griffies led the development of mom since 2000. However, mom is really a community code, and many people, both in gfdl and around the world, have made fundamental contributions to its successful development over the years.

Sicopolis model is a three-dimensional dynamic / thermodynamic model, which simulates the evolution of large ice sheet and ice sheet. It was originally created by Greve (1997A, b) in a version of the Greenland ice sheet. Since then, sicopolis models have been developed and applied to the past, present and future glaciers of polar ice caps in Greenland, Antarctica, the entire northern hemisphere, Mars and elsewhere.

Community land model is the land model of cesm (community earth system model). This is a collaborative project between the Earth Sciences, climate and global dynamics departments at the National Center for Atmospheric Research (NCAR), as well as the cesm land model and biochemistry working group. Other working groups, such as chemical climate and land ice, have also contributed to CML. The model formalizes and quantifies the concept of ecoclimatology to understand the impact of natural and human changes on climate. The circulation of energy, water, chemical elements and gases in terrestrial ecosystems plays a decisive role in climate change. The model reflects several aspects of surface heterogeneity, including components or sub models related to terrestrial Biogeophysics, hydrological cycle, biogeochemistry, human dimension and ecosystem dynamics.

ARPS model is a non-static equilibrium regional forecast system developed by the storm analysis and Prediction Center of the University of Oklahoma. ARPS model adopts generalized terrain coordinate system, arakawa-c staggered horizontal grid and second-order leapfrog leaping time integration scheme, including cloud microphysical process, sub grid scale turbulence and other physical processes. ARPS model is suitable for small and medium-sized and storm scale weather systems, such as tornado, supercell storm, etc. ARPS model is mainly aimed at non energetic high-resolution regional forecast system of storm scale, including variational assimilation of real-time data, forward prediction and post-processing module.

In the AgNPs model, the universal soil loss equation (USLE) is used to predict the erosion of a single rainfall event, even if USLE is not suitable for this purpose. A new improvement of USLE is more suitable for predicting the erosion of events, and also provides a mechanism for calculating the impact of slope runoff on erosion, which is not available in USLE.
