Tool to generate future weather data for crop and climate planning
Since last year, the CGIAR Program on Climate Change, Agriculture and Food Security has been improving on the MarkSimGCM stochastic weather generator tool, released last year. MarkSim GCM lets the user generate plausible weather data for future climates, using six climate models (or the ensemble average) and three greenhouse gas emission scenarios that were part of the IPCC’s Fourth Assessment Report. The tool is embedded in Google Earth and can also be used to generate daily data that are characteristic of current conditions. The new tool, called Marksim_Standalone, is a development of the new MarkSimGCM web application and can generate multiple realisations of years of daily data: rainfall, maximum and minimum temperatures and solar radiation. MarkSimGCM and MarkSim_StandAlone were developed by Waen Associates with CCAFS support, in cooperation with CIAT, ILRI, IFPRI, Potsdam Institute for Climate Impact Research, HarvestChoice, and the University of Oxford.
