How are the hourly data files formated and how can the files be used?

Hourly data files are extracted from the last 24 hours of "Realtime" data - data that went through automated quality checks and were distributed as soon as they were received. Missing data in the Realtime and Hourly data are denoted by “MM.”

Click on the Data description links below for a detail explanation of each Hourly file type.

Hourly files group all the Station ID's into a single file, then they are sorted by Station ID, Year, Month, Day, Hour and Minute over a 24 hour period. Example: View the Hourly file format below; hour_xx.adcp

The only except to sorting all the files listed in the Hourly2 directory is the hour_xx.adcp2 type files, the sort order is the same as above but with an addition Instrument (I) and Bin column that is sorted.

Access to Hourly Files

You can view the directory containing the hourly files here: Hourly files directory
