10m file information

Each .10 file contains data from one high resolution XBT transect.

The files are named by Line designation, year, and starting month, i.e. p379801a.10 contains data from Line PX37 for the cruise beginning in January 1998.

The first line of the file gives the number of profiles contained in that file, e.g. 97 in the example below, from p379801a.10 .

Each profile is preceeded by a header line containing:
latitude, east longitude, date (day/month/year), time (gmt), profile number.

Each profile contains 90 values of temperature (degC), written as 12i6, in thousandths of a degree. Each data value is the average over a 10-meter interval, beginning with 0-10 m through 890-900 m. Missing values (below bottom strikes, wire breaks or other end of profile) are marked -999.

The first temperature value in the example below is 14.458 degC.

Example: First 19 lines from p379801a.10 :
