File Naming:
 Each file is named using a YYMMDDHH.zip format.  YY is the year, MM the month, DD the day of the month (local day) and HH is the start time of the data file in 24-hour format, Coordinated Universal Time (UTC)

For example, a file containing data for 1:00 pm to 2:00 pm on May 10, 1999 would be named 99051013.zip.

Data Storage:
Data Files are normally available online for at least 28 days, after which they will be deleted. Data is not archived prior to deletion and is therefore unrecoverable.  Users are encouraged to download data as soon as practicable.
