GSLA is mapped using optimal interpolation of detided, de-meaned, inverse-barometer-adjusted altimeter and tidegauge estimates of sea level. GSL is GSLA plus an estimate of the departure of mean sea level from the geoid - mean sea level (over 18 years of model time) of Ocean Forecasting Australia Model version 3 (OFAM3). The geostrophic velocities are derived from GSLA and the mean surface velocity from OFAM3. The altimeter data window for input to the Delayed Mode (DM) maps is symmetrical about the map date. The width of the window is dependent on the number of altimeters flying at the time and ranges from 30 days to 14 days. The altimeter data window for Near Real Time (NRT) maps is asymmetrical about the analysis date (-21 to 4 days). For both NRT and DM, altimeter data is weighted by the difference between the analysis date of the map and the time of each altimeter observation. DM01 - Delayed Mode GSLA version 01 DM01 GSLA is a complete update of the previous version, DM00. With the growing time series of altimeter data, there have been considerable improvements to the corrections used to derive sea level anomaly (SLA). DM01 uses the latest altimeter data corrections (as of March 2018) to revise all daily maps from 1993-2019. Since June 2020, this DM01 product has been available via the AODN Portal, and supersedes the DM00 product formerly provided. The DM00 data is no longer updated, and is still available via https://catalogue-imos.aodn.org.au:443/geonetwork/srv/api/records/3162c844-d45c-491c-b326-6ae37e4079f9.

Brief description

Gridded (adjusted) sea level anomaly (GSLA), gridded sea level (GSL) and surface geostrophic velocity (UCUR,VCUR) for the Australasian region. GSLA is mapped using optimal interpolation of detided, de-meaned, inverse-barometer-adjusted altimeter and tidegauge estimates of sea level.
