C-3 Model Architecture and Component Design (3) diagrams illustrating model-related flow of information and its processing by modeling organization personnel or team. February 2-4, Florida International University FPHLM v6.1 2  CS team defined a set of style guidelines for all project members to follow.  Identify the data and participating actors (roles).  Number the information flow sequence.  Include brief description of the information flow being illustrated.  Add a legend if abbreviations/acronyms are used.  UML was chosen as the modeling language.  Diagrams were created using a UML stencil for Microsoft Visio, which provides standard UML 2.x symbols.  CS team provided instructions on how to download and use the template as well as provided references to online resources.

C-5 Verification V erification approaches used for externally acquired data, software, and models.  Verification approaches are used for externally acquired data that is used as input or preparation for input into model. No external software or models are used as integral parts of the model.  Meteorology team:  Data is imported into GIS software for thorough inspection.  Data is cross checked with other data sources when available.  For data that is updated, numerical differences between either the raw data or a derived quantity of the updated and original data are computed.  For textual data, such as HURDAT(2), standard Unix tools are used to identify changes in the data. Data is then cross checked against other sources to determine if the changes are reasonable.  For data which are GIS layers, such as ZIP Code boundaries, updated and previous layers are overlaid to visually inspect the data.
