SL_cci+ sea level trends over 2002-2018

 The XTRACK-ALES v1.1 along-track high-resolution (20 Hz) Sea Level Anomalies (see previous web news) have been used to derive a new thematic coastal sea level product: this is a database of monthly-averaged post-processed Sea Level Anomalies and associated trends estimated along the tracks at 429 selected coastal sites from 2002 to 2018. SLA are available in six different regions: the Mediterranean Sea, North-East Atlantic, West Africa, North Indian Ocean, South-East Asia and Australia. Read more »
