ESA Tutorial: Accelerating CryoSat-2 projects with cs2eo.org: A hands-on workshop and demonstration 

cs2eo.org is a CryoSat-2 data and information services platform developed by Earthwave and the University of Edinburgh for ESA. cs2eo.org currently features most CryoSat-2 datasets (including all CryoTEMPO and predicted ground tracks), most relevant ICESat-2 datasets, and overlapping airborne campaigns (CryoVEx, IceBridge, etc).cs2eo.org was originally developed to enable the download of intersecting CryoSat-2 and ICESat-2 datasets for the CRYO2ICE campaign,and has since grown into a general platform for altimetry data and information services. cs2eo.orgs users enjoy basic data access (including coarse subsetting) and intersection processing for all of its datasets, as well as advanced data access (fine subsetting, including by field value or individual glacier) and time series processing for selected datasets. During this demonstration, we will explore cs2eo’s capabilities and explain how they can be used to streamline common altimetry tasks. Join us to learn more about how cs2eo could enable your next project.
