IHACRES model is a lumped conceptual rainfall runoff model based on unit hydrograph principle. It is composed of two basic modules in series: in the nonlinear module, rainfall is transformed into effective rainfall; in the linear module, effective rainfall is further transformed into runoff. The model is suitable for a series of spatial and temporal scales.

HYDRUS-1D model is a finite element model, which is used to simulate the one-dimensional motion of water, heat and multiple solutes in variable saturated media. The model solves Richards' saturated unsaturated water flow and Fickian based advection dispersion equations of heat and solute transport.

ALMANAC model is a practical model, which was first used as a part of EPIC model to simulate the decline of land productivity caused by soil erosion. ALMANAC model can simulate crop growth process and soil water balance process, including: light interception by crop leaves, biomass accumulation, biomass distribution in different organs of crops, full utilization of water by crops, absorption of nutrients, and constraints of environmental factors on crop growth process, such as water stress, temperature stress and nutrient stress. The ALMANAC model provides a util editor. This is a very friendly interface database editing program, can directly provide users with the input variable database prompt operation.

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.
