The Workshop on improved satellite retrievals of sea-ice concentration and sea-ice thickness for climate applications will be held on October 9-11, 2017, at Bundesstrasse 53, 20146 Hamburg, Germany.

This workshop is jointly organized by the Integrated Climate Data Center (ICDC), University of Hamburg, and the Max-Planck Institute for Meteorology (MPI-M), Hamburg, and co-sponsored by CliC, CliSAP, and ESA-CCI, aiming at both experts for sea-ice remote sensing and sea-ice modelling. See below for further details.

Workshop Organizers:

Stefan Kern
Integrated Climate Data Center (ICDC), University of Hamburg

Dirk Notz
Max-Planck Institute for Meteorology (MPI-M), Hamburg

Scope of the workshop:
New sensors and new algorithms have over the past few years allowed for sometimes significant progress in our ability to estimate sea-ice concentration and sea-ice thickness from space. In addition to existing sensors such as CryoSat-2, SMOS, AMSR2 and ASCAT, the launch of new sensors such as ICESat-2 and additional Sentinels will further widen our capabilities to ever more accurately measure the state of sea ice from satellites.

We invite experts both for remote sensing and for large-scale modeling to discuss and outline the most promising opportunities and best practices in the use of existing and future satellite sensors for the remote sensing of sea-ice concentration and thickness, and the use of such data in large-scale modeling applications.

Tentative agenda:

Day 1 – afternoon – Session 1: Understanding each other
– An introduction to current practices in using and simulating sea-ice concentration and thickness in large-scale models
– An introduction to current practices in the retrieval of sea-ice concentration and thickness from remote sensing observations

Day 2 – morning – Session 2: Understanding and reducing errors
– Limitations and possibilities in remote sensing and modeling
– Sensitivities
– Setting and understanding of priorities in retrieval and modeling
– Optimization of approaches, improvement of products, reduction of product uncertainties

Day 2 – afternoon – Session 3: Quantification of uncertainties and product evaluation
– General differences between retrieval and modeling
– How are uncertainties derived?
– How reliable / valid are these uncertainties?
– What are the current best practices to evaluate products and their uncertainties? What can be improved?
– Who takes which information out of which source? What are the user groups for uncertainties and validation results?

Day 3 – morning – Session 4: Harvesting the fruit: The scope of final products
– Summary of the previous days’ results
– Parameters to be included in products of sea-ice concentration and sea-ice thickness: must have / valuable add-on / nice-to-have / irrelevant
– Review of current products
– Recommendations for future products (taking into account foreseen technical progress)
– Planning for a possible joint paper/workshop report
