Meteorological data is currently stored in monthly files which have data available at varying intervals. Therefore the maximum run duration is 1 year. Otherwise the simulation will fail to complete.

• We would suggest using Google Chrome or Mozilla Firefox. There are known issues with placement and functionality within older instances of Microsoft Internet Explorer.
