DATA DESCRIPTION
================

Different types of tide gauge data are available in this server :
- Raw hourly values, latency 1 week, no quality control
- Quality controlled hourly values, latency 2 months
- Mean sea level values (daily, monthly, annual)

Tide gauge data is organized as follows :

DATA FORMATS
============

UNITS :
------
Hourly and 10 min. sea level height values are provided in TU+0
Heights are expressed in centimeters for hourly values (IHO standard),
in meters for 10 min. values or mean sea levels

FILE NAMINGS :
-------------
sCCCCC[YYYY][WW].eee Note : [] means optional

s : prefix ’f’ for 10 min. values
’h’ for hourly values
’d’ for daily values
’m’ for monthly values
’y’ for yearly values
CCCCC : SONEL station/site identification code,
see file site_codes.txt
YYYY : year of data
WW : week of data
eee : extension ’slv’ for sea level values.
’bar’ for pressure values

FILE CONTENTS :
--------------
Hourly sea level data files are provided in SHOM/IHO format.
The format is as follows :

Each line contains 27 values
- 3 fields of 4 integer characters :
- the year
- an internal SHOM harbor code
- the day of year

- 24 fields of 4 integer characters :
- sea level heights, from 0h to 23h TU+0, in centimeters
Note : 9999 means no data or bad value (as it is the
case for the valeur 99.999 in the 10 min. data).
