Mediterranean Sea - Seasonal mean and Climatology Maps of Sea Level Anomalies

Types of dataset: Ssalto/Duacs multimission altimeter products. Since January 1993, the long delayed-time dataset allows to compute statistical means of MSLA over different periods of time. Averaged MSLA and Climatological MSLA are created from weekly and/or daily Ssalto/Duacs - DT MSLA - Merged Product - based on the best sampling available in time (i.e. "all sat merged" serie, see DT-(M)SLA product sheet for more information).

Three kinds of means are proposed:

  • Monthly averaged MSLA corresponds to the weekly maps of delayed-time sea level anomalies averaging month by month from January 1993. We obtain one file and one map per month since January 1993.
  • Seasonal mean of MSLA corresponds to the weekly maps of delayed-time sea level anomalies averaging season by season. We obtain one file and one map per season (JFM - AMJ - JAS- OND).
  • Climatological monthly MSLA are calculated by averaging the weekly maps of delayed-time sea level anomalies over a same month from January 1993 to the last extension of the Delayed-Time series. We obtain one data file and one map for each month.

Contents: multimission gridded sea surface heights computed with respect to a twenty-year mean profile [1993-2012], and including the seasonal variability (no annual cycle is removed).
Use: long-term variability, seasonal and climate studies.

Climatological Maps of Sea Level Anomaly

Description: The climatological Maps of Sea Level Anomaly are calculated from the maps of delayed-time sea level anomalies over a same month from January 1993 to the latest extension of the Delayed-time serie. We obtain one data file and one map for each month.
