Updated data received July 2019 from IDEAM had a distint reference level shift at 18 UTC 09 Sep 2016. Subsequenty, IDEAM provided a correcton of -169 mm that was applied. The corrected data agreed well with altimeter data. The data have been linked to tide staff zero by the originators. However, the following level correction was applied based on information provided by the originators and confirmed with hourly residuals. period value added ( (hour)day/month/year ) to original(mm) ----------------------------- --------------- (00)01/01/1993-(23)21/05/2008 +150 (06)01/06/2008-(05)01/08/2008 +350 This adjustment is uncertain to a few cm. Comment : The data contain numerous gaps and timing is poor during some segments. The comparison of daily values with AVISO alimeter data suggests the reference level is steady 1993-2008, after which there is a upward trend to the difference, suggesting a possible sinking of the station. Also, the difference suggests Aug-Dec 2002 high by about 15 cm. Hourly residuals show a step- function jump in the mean level 25 Jul 2011, though it is not clear that it is in error since the long-term mean is steady.
