Sea level Climate Change Initiative (CCI)

This needs an alt tag!!!

Completed project

Project start: April 2015  |  Project end: April 2018
Funder: European Space Agency (ESA)
Principal Investigator: Dr Graham Quartly

The main objective of the sea level CCI project is to produce and validate a Sea Level Essential Climate Variable (ECV) product. It represents the first phase of the ESA Climate Change Initiative program that aims at setting up in a second phase an "operational processing capacity of Earth Observation data".

The final output was a gridded time series of satellite-derived sea level data that can be used for climatological studies. Such studies include regional sea level rise as well as long-term variations in circulation, and the ability to investigate variations in sea height associated with El Nino. 

PML was involved in interpreting the data in the Arctic, where a particular challenge is distinguishing between the radar returns from ocean and from ice sheets. See further information for papers arising from the project.
