Altimeter product global Mean and Climatologies - Heights (multimission, level 4)

Ssalto/Duacs multimission gridded sea surface heights products. From January 1993 to the last extension of the Delayed-time products, the long delayed-time dataset allows to compute statistical means of Maps of Sea Level Anomalies (MSLA) over different periods of time.

Computed with respect to a twenty-year mean profile [1993-2012], and including the seasonal variability (no annual cycle is removed).

Statement

Averaged MSLA and Climatological MSLA are created from daily Ssalto/Duacs - DT MSLA - Merged Product - best sampling available in time (i.e. "all-sat-merged" serie, see Global Ocean gridded L4 Sea Surface Heights and derived variables reprocessed (1993- ongoing) and NRT for further 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 daily 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 daily maps of delayed-time sea level anomalies over a same month from January 1993 up to the last extension of the Delayed-time products. We obtain one data file and one map for each month.
