Overview

Decision Support System for Agrotechnology Transfer (DSSAT) is software application program that comprises dynamic crop growth simulation models for over 40 crops. DSSAT is supported by a range of utilities and apps for weather, soil, genetic, crop management, and observational experimental data, and includes example data sets for all crop models. The crop simulation models simulate growth, development and yield as a function of the soil-plant-atmosphere dynamics. DSSAT has been used for many applications ranging from genetic modeling to on-farm and precision management to regional assessments of the impact of climate variability and climate change. DSSAT has been in use for more than 30 years by researchers, educators, consultants, extension agents, growers, private industry, policy and decision makers, and many others in over 150 countries worldwide

CLIMsystems has worked closely with DSSAT to create a perturbation tool for incorporating climate change factors into the DSSAT software system. CLIMsystems has applied the latest CMIP5 data for temperature, precipitation and solar radiation for the globe and processed up to 40 General Circulation Model patterns for each variable for easy access in the DSSAT Perturb.

In DSSAT Perturb you can choose an individual GCM or use the more widely recommended approach which is to apply an ensemble of models. You can also select one of four representative concentration pathways (RCP 2.6, 4.5, 6.0 and 8.5). With DSSAT Perturb you can control the climate runs and save the perturbed data to an output directory of your choice.
