Introduction:

The CGIAR Programme on Climate Change, Agriculture and Food Security has been improving on the MarkSimGCM stochastic weather generator tool. MarkSim GCM lets the user generate plausible weather data for future climates, using models and scenarios from the IPCC’s Fourth Assessment Report. The new tool, Marksim_Standalone, is a development of the MarkSimGCM web application. It is designed for computer users who need to process a lot of data without the need for a user interface. The tool can generate multiple realisations of years of daily data: rainfall, maximum and minimum temperatures and solar radiation. It produces weather files that are fully compatible with the Decision Support System for Agrotechnology Transfer (DSSAT) crop modelling system. (CCAFS, 5/4/2012)
