Data Files Download Information

  - Click on the download link to download a zipped file of the data type selected.
  - Double click on the downloaded archives if they didn't open automatically.
  - If the format is not recognized, the following applications can be used to unzip them:
    • Macintosh - Archive Utility, Unarchiver,...
    • Windows - WinZip
    • Unix, Linux - unzip (note: gunzip will not work with these files)

  - Depending on how your operating system preferences are set, you may need to open unzipped ascii files (i.e., filenames ending in .dat) with the appropriate application rather than by double-clicking them directly.
