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
