This page is kept for those that want to use the legacy v1 version. For current download, source, and information please go to: https://code.usgs.gov/modflow/mf-owhm ----------------------------------------------------------------------------------------------------------- The One-Water Hydrologic Flow Model (MODFLOW-OWHM, One-Water) is an integrated hydrologic flow (IHM) model that is an enhanced fusion of multiple MODFLOW (MF) versions. While maintaining compatibility with existing MF versions, MF-OWHM includes: linkages for coupled heads, flows, and deformation; facilitation of self-updating models, additional observation and parameter options for higher-order calibrations; and redesigned code for faster simulations. MF-OWHM represents a complete IHM that fully links the movement and use of groundwater, surface water, and imported water for consumption by agriculture and natural vegetation on the landscape, and for potable and other uses.

Please go to project home (https://hypeweb.smhi.se/model-water/) or wiki-pages (http://hype.smhi.net/wiki/doku.php?id=start) for more information. The hydrological model HYPE is developed at the Swedish Meteorological and Hydrological Institute (SMHI). The model simulates water, nutrients and other substances in small and large river catchments. Included in the project is HYSS, which is needed to run the model. It handles input and output and the simuation over time.

MieConScat is a GUI/Console program for generating MIE SCATtering data as a table of cross sections. It can generate scattering cross sections over specified angular ranges and total absorption cross sections. It was initially developed to aid work with optical particle counters (OPC) especially when CONverting data between cross section and diameter space. These methods are described in Rosenberg et al. 2012, Particle sizing calibration with refractive index correction for light scattering optical particle counters and impacts upon PCASP and CDP data collected during the Fennec campaign and CDP data collected during the Fennec campaign, http://www.atmos-meas-tech.net/5/1147/2012/amt-5-1147-2012.html

General Ocean Turbulence Model

GeoSolid3D produces 3D geologic solid models, incorporated into the aquifer and confining units of the USGS ground water models, Modflow and Sutra. Uses GIS data of DEMs, geologic maps, and maps of river, watershed, recharge, and aquifer parameters.

Ultrascale Visualization Climate Data Analysis Tools (UV-CDAT), is a powerful and complete front-end to a rich set of visual-data exploration and analysis capabilities well suited for climate-data analysis problems.

This is an simple ecological model for lakes and reservoirs that contains a very detailed description of the most relevant nitrogen processes. The model is not very complete, but the main intention is to develop a library to be coupled with other models and use the full-mixed model as a testing version. A lot of things can be improved. I will read all the suggestions but I cannot promise that I will include all of them. Every new part of the code will contain the name of the author. If someone contributes improving the capabilities of this model in a substantial way, I will include that person as co-author of the model in the next version release. I hope this will promote people to contribute. Of course, fixing bugs or minor changes will also be mentioned with the corresponding author. Thanks a lot. I hope this can be the seed of a Open Source Community of Ecological Modellers.

A library collection of FORTRAN 90 subroutines and functions for the handling of raster images and for remote sensing applications. The 'fwtools' name evolved from 'framework tools'.

* Please check latest update on https://github.com/igps-ftk/iGPS A tool written in Interactive Data Language (IDL), for processing and analyzing daily continuous GPS position time series. It can read time series in various formats, detect outliers, remove abnormal observation spans, find jumps, extract common-mode components(CMC), etc.

This project contains some programs that designed to process gravity data through applying of the reductions to determine the Bouguer gravity anomaly and to model the subsurface structures by forward and inverse methods as well as some programs to determine geo‌detic parameters from geo‌potential mo‌dels. This project may be useful in Geodesy and Geophysics.

BRAMS IS A NUMERICAL MODELING SYSTEM DESIGNED FOR REGIONAL SCALE ATMOSPHERIC FORECASTING AND RESEARCH, WITH FOCUS ON ATMOSPHERIC CHEMISTRY, AIR QUALITY AND BIOGEOCHEMICAL CYCLES.

The goal of this project is to provide a couple of Fortran code to those students who selected the course of "Climate Modeling" in the department of atmospheric and oceanic sciences at Peking University. 这个项目的目标是给选择“气候模拟”课程（北京大学大气与海洋科学系）的同学提供与课程学习有关的源代码程序。 We are subject to GNU/GPL license and happy to open the code to the public. 我们遵守GNU/GPL协议，并乐于开放代码给所有需要的人。

The latest ESMF development is happening in GitHub: https://github.com/esmf-org/esmf https://earthsystemmodeling.org The Earth System Modeling Framework provides high-performance software infrastructure and superstructure for the construction and coupling of climate, weather, and data assimilation applications.

A collection of Fortran interfaces to the most common Open Source GIS libraries, plus some more Fortran-specific tools.

Add-ons to the ECMWF GRIB API. This project is about developing and maintaining add-ons to the GRIB API, like language bindings or documentation. The main GRIB API page is at http://www.ecmwf.int/products/data/software/grib_api.html

An integrated atmospheric model for weather and climate prediction and simulation. It includes portable versions of global spectral model, regional spectral model, and non-hydrostatic mesoscale spectral model.

Geostatistical software made within research centre CERENA/CMRP. NOTE: GEOMS2 (beta release) is available for download in this link https://sourceforge.net/projects/geoms2/

Glimmer is an open source (GPL) three-dimensional thermomechanical ice sheet model, designed to be interfaced to a range of global climate models.

HydroSed2D is a two-dimensional numerical model for hydrodynamics and sediment transport on unstructured mesh.

The hsdar package contains classes and functions to manage, analyse and simulate hyperspectral data. These might be either spectrometer measurements or hyperspectral images through the interface of rgdal.

This project provides a simple atmospheric model as a Fortran 90 library. The model solves some of the most important processes of the tropical climate system, and is suitable for example for studying ocean/atmopshere interactions.
