| **The modeling data consists of several files that are inputs and outputs from the modeling software. These files have been combined into one zip file in order to save space. These are large files and may take a long time to download. If you are using Windows XP, Microsoft included an unzip program as part of XP, so just double click on the file and it will open in a new window and you can extract the file that way. If that doesn't work, or if you are using an older version of Windows, then you will need to get an unzip program to do this for you. Once the files are extracted they are meant to be used with the modeling software, but the raw data in the files may be viewed with a program such as notepad. | ||
