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.

MSSW is a computer program to simulate the movement of solute in water. The program solved Richards' saturated unsaturated water flow equation and solute transport convection dispersion equation numerically.

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.

Biosphere 3D is an open source project aimed at interactive landscape rendering based on Virtual Earth. The software system supports multiple scales, but it is mainly used to create realistic views from the line of sight level or near ground level. The software is released under the license of MPL and developed by lennal 3D for personal computers. Biosphere 3D was first released in 2007 by the visualization and data analysis department of the Zuse Institute in Berlin. Applications include landscape planning, landscape architecture, visual impact assessment, such as wind farms, power stations, land-use planning, archaeology, urban planning and forestry, enabling them to roam through landscape scenes or nearly reconstructed historical landscapes and gardens. Biosphere 3D, originally funded by the Federal Ministry of education and Research (Germany), was designed as a pure landscape visualization system in the "silvisio" of the R & D project.

At present, the plastic tarpaulin used in soil fumigation process has been proved to be able to penetrate into the fumigation steam and cause obvious loss to the atmosphere. New low permeability membranes are being developed to reduce fumigant emissions and improve efficacy. A fast, reliable and sensitive method is needed to measure the permeability of various membranes that may be used in new management practices. Filmpc provides a method for estimating the mass transfer coefficient (H) of fumigants in agricultural films. H is a measure of diffusion resistance. Unlike other permeability measurement methods, h is an attribute of film chemical combination, independent of the concentration gradient of the whole film. The model relies on a mass balance method, and adsorption and diffusion are carried out on the membrane. The results show that this method produces a sensitive and reproducible method for measuring membrane permeability.

It is a new process based cotton model to simulate the growth and development of Upland Cotton (Gossypium hirsutum L) with minimal data input during the whole growing season. CPM predicts the final cotton yield for any combination of soil, weather, variety and management behavior.
