APSIM Downloads for 17/18

 

For the 2017/18 year there were 2103 non-commercial licenced users registered (an 11% increase on the previous year). This resulted in some 3775 downloads of APSIM (all versions as some users download older versions or use multiple versions).

APSIM is being used in 116 countries around the world, around the same number as the previous year. In Australia there are 482 users (up from 462 the previous year), with 157 in Queensland, an increase of 51 users. In New Zealand there were 46 users.

SILO Redevelopment

Are you aware that the SILO climate database has been redeveloped. The new system is now available for use. Some benefits of the new system:
• all datasets are now free of charge (supported by the Queensland Government’s Open Data initiative)
• data can now be distributed as they are licensed under the Creative Commons Attribution 4.0 licence
• users can now download gridded data (data are in NetCDF format). Please see the new web site for more information about accessing the gridded data.
• the new web interface is much easier to use than the old interface
• the new Application Programming Interface (API) enables users to query the amount of observed data available at each station
• patched point datasets are available at nearly all (18,700) stations (previously patched datasets were only available at a modest subset of the stations)

The APSIM SILO mirror based out of Toowoomba will stop working soon. You will need to switch the new SILO climate database as soon as possible.

You can find the SILO Getting Started Guide in the Technical documentation section of http://www.apsim.info/Documentation.aspx

APSIM-Wheat: Documentation

Author: Chris Murphy/Tuesday, 29 April 2014/Categories: Features

Find out the details of the APSIM-Wheat module and understand how wheat crop is simulated in APSIM (current for v7.5 R3008).

This updated documentation presents the processes modelled in APSIM-Wheat, and gives the equations and defaults parameter values that are used by the model. Graphic illustrations and figures have been added to help the understanding on how the model is functioning.

APSIM-Wheat simulates wheat growth and development at a daily time step, in response to the climatic factors (radiation, temperature and rain), soil characteristics and management practices.

The documentation presents in details the different processes involved, including crop phenology, biomass accumulation, partitioning and re-translocation, as well as root, leaf and grain development. Response to water limitation and nitrogen are also documented and a list of the main reference and model parameters is given at the end of the document.

The updated documentation can be found here.
