MarkSim Standalone for Advanced DSSAT Users


Generate Weather for Future Climate, from Command Line

Theme 4 of the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS), in collaboration with Peter Jones (Wane Associate), released a new version of MarkSim Weather Generator for DSSAT users: MarkSim Standalone.

From the CCAFS website:

MarkSim Standalone combines the basic routines from the original MarkSim version and the new MarkSimGCM Web application. The standalone version is designed for computer users that need to process a large amount of data in a batch process. Same as the MarkSimGCM, MarkSim Standalone can be used to generate weather data from six GCM model results and three SRES scenarios, along with an ensemble of the six GCM’s.

MarkSim Standalone is specifically designed to be used with DSSAT; it uses CLI Climate Profiles (existing, or constructed by the user) to create new CLI files and WTG files for the simulated weather data under a range of GCM’s and scenarios. The EXE runs from the DOS prompt (or a system program call). It will read a directory, work out a list of the CLI files in that directory, and create subdirectories for each CLI file. In each of these it will place up to 99 replicates of yearly weather data and a new CLI file describing the climate under the particular situation of GCM/scenario/year for which the user called.
