Quality Assessment

Comments

Data up to 26 June 1992 are not corrected for atmospheric pressure. Conversion from total pressure to pressure due to sea water has been done using a fixed atm. pressure of 1013 mbar. After 26 June 1992 the data are corrected for atmospheric pressure using data from a pressure sensor placed on land. Salinity not measured, sea level elevation calculated from pressure using a sea water density based on measured temperature and a salinity of 31.5ppt.

All pre 1995 data have been adjusted by -510cm to refer to LAT.

Possible datum shift of approximately -15cm on 14 April 1993. Residuals are extremely noisy in the early part of 1993.

1996 data have been collected with a 15 minutes interval, but it slips 1 minute approximately every month.

Possible datum shift of approximately +0.14cm on 30 April 1997.
