ESA's Climate Change Initiative (CCI) has conducted a number of projects related to sea level, namely the Sea Level CCI project, the Greenland and Antarctic Ice Sheet CCI projects, the Glaciers CCI project and the Sea Surface Temperature CCI project. Using the improved, consistent, and well-documented data products from these CCI projects, it is time to re-assess the sea level budget closure. This is the aim of the CCI Sea Level Budget Closure (SLBC_cci) project.
The project analyzes results based on CCI products in conjunction with data products from ocean profilers (e.g., Argo), GRACE-based ocean mass change assessments, and model-based data for glaciers and land hydrology. Closure of the global mean sea level budget and global ocean mass budget are being investigated in a coherent way and the quality of CCI products is being assessed. In addition, the regional variability of sea level and its steric and mass components are investigated in a case study for the Arctic Ocean. These activities are intended to prepare the way to more comprehensive and more operational assessments of the global and regional sea level budget.
The poster outlines the envisaged developments and prospects from the project. It gives an overview on the status of datasets available and the degree of sea level budget closure at the first iteration of collected datasets.
