CRYO2ICE is a campaign that increased the ground track intersection of the CryoSat-2 and ICESat-2 satellites over short time intervals. The orbit change of CryoSat-2 is an enabling step for applications that require co-incident data, such as measuring snow depth and capturing the temporal variation. In addition to aligning the satellites, an efficient data access layer to identify coincident CryoSat-2 and ICESat-2 data measurements is required.

The Cryo2Ice Coincident Data Explorer enables users to visualise the spatial intersections for a given time window and download the ESA and NASA data products. The website’s unique temporal separation time functionality allows users to select intersects that are close in time (e.g. 3 hours) up to a 28 day separation, providing useful application for Sea Ice, Land Ice and the Ocean. The intuitive and reactive interface enables users to choose the area of interest by specifying a bounding box or drawing a polygon. Easy to use download scripts allow users to download only their intersecting data, saving a large amount of both download time and data preparation time. The provided KML file allows users to save the visualisation component of their results and view it at a later time. The robust implementation makes it possible to run large queries in batch mode and receive the results via email.

The website provides access to CryoSat-2 LRM, SAR and SARIn mode data and ICESat-2 ATL06, ATL07, ATL10, and ATL12 products. Combined datasets for CryoSat-2, linking the LRM, SAR, and SARIn L2 products, and for ICESat-2, linking the ATL06 and ATL07 products, allow users to view and intersect these products at the same time. Predicted ground track data is available, allowing users to view and plan for future CryoSat-2 and ICESat-2 satellite passes and intersections. The portal additionally provides access to CryoTEMPO-EOLIS Point and Gridded products.

Airborne missions such as Operation IceBridge data sets are available, with the CryoVex data and its following campaigns coming in the future.

The website allows intersections to be computed between any pair of available datasets from different missions, as long as they coincide in time. One could intersect the ICESat-2 ATL07 product with CryoSat-2 SAR mode data, or go outside of the CRYO2ICE scope and intersect airborne Operation IceBridge data with EOLIS Point Product’s swath elevation. Each dataset available on the website can also be queried in single mode, allowing users to view the data independently rather than searching for intersections.

This poster will detail the Cryo2Ice Coincident Data Explorer and gather feedback for additional features, capabilities and datasets. A new combined CryoSat-2 and ICESat-2 product, created to make coincident data even easier to use and download, will also be presented.
