Open Source Fortran Earth Sciences Software

gputils is a collection of tools for Microchip PIC microcontrollers. Its goal is to be fully compatible with Microchip's tools, MPASM, MPLINK, and MPLIB.

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.

A spectral element method for 2D wave propagation and fracture dynamics, with emphasis on computational seismology and earthquake source dynamics.

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'.

Free cross-platform viewer for seismic data in SEG-Y format (Revision 1 draft 6 and its modifications).

Generic data-assimilation toolbox written in java, with native (c and fortran) libraries for high performance computing. Provides tools to couple to your own model and a wide range of algorithms, ranging from parameter calibration to Kalman filters.

Engineering, analysis and computing tools for marine and coastal science and technology

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.

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.

CPSeis is the open-source version of ConocoPhillips' former seismic processing system. Uses Fortran 90 and C/C++ layers for I/O. The new system was designed using an MPI-parallel model and works well on Linux clusters or on individual workstations.

WEST (Wind Energy Simulation Toolkit) is a wind simulation application. It can be use to obtain high resolution results at various altitudes.

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

A model of the water, C, nutrients and microbial communities of the Amazon River. This project is still in development, the code may not be functional at this time. Most recent code version is under Files, labeled ROCA-date

Development of new data assimilation techniques for ocean models

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.

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。

General Ocean Turbulence Model

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/

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.

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.
