In Situ Relative Sea Level Trends. Trend is presented by means of false color arrows. This product (developed for EMODnet Physics) uses the Permanent Service for Mean Sea Level (PSMSL) data bank on sea level data from the global network of tide gauges since 1900. The trend is available for stations with at least 30 years of measurements.

Global Sea Level Anomalies - this product uses the PSMSL relative sea level trends. It shows annual variation compared to a long term trend (at least 30 years of recordings). Use "viewparams" parameter to specify: (1) syear (start year) from 1900 to 2015 (2) eyear (end year) from 1900 to 2015 (3) ayear (anomaly year) from 1900 to 2015 --- Note1: syear < eyear, syear <= ayear <= eyear --- Note2: eyear - syear >=30 -- Example: viewparams=syear:1900;eyear:2015;ayear:1900
