Sri Lanka has an annual rainfall between 750 and 6,000 millimeters (mm), with large spatial and temporal variation. The availability of clean drinking water is a national imperative, but agriculture consumes the bulk of available water resources. Economic development, population pressure and rising demands from different sectors are placing increasing pressure on available water resources. With climate change threatening, there is a danger that the demand for water will outstrip supply - particularly in the Dry Zone of Sri Lanka where most irrigation schemes are located.

MarkSimGCM is a stochastic weather generating tool, which uses the well-known MarkSim application, a tool that generates simulated daily weather data specifically designed for use in the tropics, including rainfall, maximum and minimum temperatures and solar radiation. It provides files of daily weather data that are completely compatible with the DSSAT (Decision Support System for Agrotechnology Transfer) crop modeling system
