Esap-95 software package contains a series of site salinity modeling software programs for analyzing and predicting soil salinity information. Esap-95 software package currently contains three software programs: esap-rssd, ESAP calibrate and ESAP saltmapper. The esap-rssd program is designed to produce the best results of soil sampling designs from bulk soil conductivity surveys. Esapcalibrate program is designed to estimate stochastic (regression model) and deterministic (soil) theoretical basis) calibration equations; i.e. These equations are eventually used to predict the spatial values of one or more soil variables, derived from electrical conductivity measurements. ESAP saltmappercheng program can be used to produce high-quality 1D or 2D graphics, output electrical measurement data or predict soil variables.

Geosfm hydrological model is studied by the center for earth resources observation and Science (EROS) of the U.S. Geological Survey (USGS). Its biggest feature is that the satellite remote sensing precipitation products can be directly used as the driving parameters of the model. The geosfm hydrological model has been applied to the Nile River Basin in Africa, Mekong River in Asia and bagmati River Basin in Nepal. Geosfm can create a common visual environment to monitor hydrogeological conditions in a wide range of areas, including topographic analysis, data assimilation and time series processing, and display the monitoring results.

IBIS model is used to describe the input, output and I / obuffer behavior characteristics of IC devices, and to simulate the interaction between buffer and on-board circuit system. The core content of IBIS model is the buffer model, because these buffers produce some simulated waveforms, so the simulator uses these waveforms to simulate the influence of transmission line and some high-speed phenomena. Specifically, Ibis describes the input and output impedances (in the form of I / V curves), rise and fall times, as well as pull-up and pull-down in different situations. Engineers can use this model to analyze Si, crosstalk, EMC and timing in the circuit system on PCB.

The n3dade model is used to evaluate solute transport in three-dimensional nonequilibrium porous media.

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.

The common land surface model was developed by scientists interested in land model for public use and further development. The main characteristics of the model include sufficient non-uniform interlayer to fully represent soil temperature and soil moisture, and multi-layer parameterization of snow process; clear treatment of liquid water and ice water quality in snow soil system; runoff parameterization under the concept of topmeod; a canopy photosynthetic conductivity model, which describes the simultaneous transfer of carbon dioxide and water vapor in plants; and a model of canopy photosynthesis conductivity; The sub grid fraction of energy and water balance is tiled. CLM has been widely evaluated in offline mode and coupled with the NCAR community climate model (CCM3).

As a global 3D atmospheric chemical transport model (CTM), geoschem mainly aims at the source and sink of atmospheric components and the physical and chemical effects in the transport process, so as to simulate the actual concentration distribution and evolution process of each component. GEOS Chem uses the meteorological plants from GEOS assimilation provided by NASA's global modeling and data assimilation Office (gmao) as the initial field to drive the model. The geoschem model includes a detailed tropospheric ozone NOx VOC aerosol Hox chemical process. It fully considers the joint effect of emission sources and natural sources. It considers that the emission of CO, NOx and SO2 is taken as the default in geoschem, using Edgar 3.2's monthly global inventory in 2000, while the anthropogenic non methane VOC is used as the default, using retro 2000 as the default Geoschem uses the advection algorithm of tpcore to simulate the horizontal transport process, which is consistent with the GEOS GCM meteorological simulation, while the convective mass flux calculation includes wet deposition, dry deposition and sea salt deposition. The geoschem mixing in the boundary layer uses a non local scheme, and the simulation of mercury is extended from the original geoschem air sea coupling simulation to a coupled atmosphere ocean land model.
