The GEFSOC modelling system is available for download under a General Public License (GNU) agreement. This means it is available for download  free of charge to anyone wishing to use it for research, planning or education purposes. The system allows the user to make estimates of soil carbon stocks and changes at the national and regional scale. Use of the system requires regional or national scale soils, climate and land use data sets assembled in a GIS in a standardized format. For details of the formatting procedure and minimum computing requirements, please see the 'GEFSOC User Manual'. There are also some answers to frequently asked questions on the FAQ's page of this site.

Download of the GEFSOC system is password protected (to enable us to monitor the uses to which the system is being put and by whom which will help us with system development in the future).

The GEFSOC Modelling System User manual has been designed to take you through all of the stages necessary for use of The GEFSOC Modelling System, from minimum data and computing requirements through to displaying results. Use of The GEFSOC modelling system is not recommended without consultation of the user manual.

To obtain the password please email the project coordinator Dr Eleanor Milne with your name, title,  address and a brief description of how you plan to use the system eleanor.milne@colostate.edu.

The GEFSOC Modelling System

During the GEFSOC Project national and regional scale data sets of soils climate and land use have been collated and formatted for 4 case study areas, Amazon-Brazil, The Indian part of The Indo-Gangetic Plains, Jordan and Kenya. In addition, existing site scale datasets have been used for model evaluation purposes. To access these data sets please contact the Project Co-ordinator Dr Eleanor Milne, or the case study country Principal Investigators:

Amazon Brazil                     Professor C. Cerri  

The Indo-Gangetic Plains      Dr D.K. Pal

Jordan                               Dr Z. Rawajfih     

Kenya                                Dr P. Gicheru

SOTER Data sets

The GEFSOC project has developed consistent soil and terrain (SOTER) datasets for four case study areas: Amazon-Brazil, the Indian part of the Indo-Gangetic Plains, Jordan, and Kenya. These data sets, plus documentation in PDF format, may be accessed freely by clicking on the following links:
