Randolph Glacier Inventory
Glaciers_CCI contributed significantly to the Randolph Glacier Inventory.
Greenland Glacier Inventory
The project team generated an inventory all glaciers and ice caps on Greenland together with the EUFP7 poject ice2sea. To serve the needs of different user communities, it assigned to each glacier one of three connectivity levels with the ice sheet (CL0, CL1, CL2; i.e. no, weak, and strong connection) to clearly, but still flexibly, distinguish the local glaciers and ice caps (GIC) from the ice sheet and its outlet glaciers.

We assessed the elevation change of Greenlands glaciers and ice caps using ICSSat data from October 2003 to March 2008. We performed several filtering techniques to minimise outliners.

The Climate Research Data Package (CRDP) can soon be downloaded here.
In the following, the products which will be generated during the Glaciers_CCI project will be presented and described shortly. More details can be found in the Product Specification Document (PSD)
- Glacier area – glacier outlines in a digital vector format along with a number of topographic attributes (e.g. mean, minimum and maximum elevation, mean aspect and slope) for each entity as relevant for a glacier inventory
- Elevation change – elevation differences for entire glaciers from DEM differencing (at grid cells) or time series at specific points from altimetry (at footprint/cross-over points)
- Surface velocity – surface displacement fields will be calculated for selected glacier parts; the locations will depend on trackable features (optical contrast or radar intensity features)
Image correlation software CIAS
Simple, free correlation software to compute displacements and other offsets between two images. The software can be downloaded here.
Further tools and applications for visualisation of final products of the Glaciers project will be published here soon.
