CNRFC Data Archive

The CNRFC maintains an archive of several of our products, including text, images, and gridded files. The archive is organized by year, month, and product folders. To search the archive:

  • Select an archived product from the drop-down menu
  • Select the year
  • Select the month

You can further narrow your search results:

  • View products for all days of the selected year and month (default)
  • Select products within a specific range of dates of the selected year and month

All archived text data are stored with the product name followed by the archive date/time stamp (YYYYMMDD.HHMMz) where 'YYYY' is the year, 'MM' is the month, 'DD' is the day, and 'HHMM'z is Hour and Minutes in Coordinated Universal Time(z). Gridded files are stored in netCDF format (.nc extension) and zipped (.gz) to conserve disk space and reduce download times.

The [MM/YYYY] located at the end of each item listed in the product menu is the earliest month/year that contains archived data for that particular item. An asterisk following the date (e.g. 12/2003*) indicates an incomplete dataset.
