CliC, IASC and SCAR continue cooperation for the next 5 years

During the Arctic Science Summit Week 2013, a trilateral agreement in form of a 5-year Memorandum of Agreement (MoA) between WCRP Climate and Cryosphere Project (CliC), the International Arctic Science Committee (IASC) and the Scientific Committee on Antarctic Research (SCAR) was signed. It supersedes the WCRP/IASC/SCAR Agreement of 2008. The Parties share common goals of working internationally and across disciplines to increase the understanding of the cryospheric elements of the Earth’s climate system and their interconnections. IASC, SCAR and CliC have a long history of successful collaboration through a number of activities and initiatives involving ice sheet mass balance, sea ice, permafrost, and polar oceanography.

Update from the WCRP Data Advisory Council meeting

- contributed by Walt Meier

The WCRP Data Advisory Council (WDAC) had its second session on 4-5 March 2013 in Darmstadt Germany. Representatives from CliC, CEOS, CLIVAR, CGMS, GEWEX, AOPC, WGNS, and SOLAS attended, as well as other invited guests. One focus of the meeting was on data inventories – systematic collections of information on data products. Several inventories have been developed or are planned and WDAC can help coordinate, identify gaps, and work towards filling those gaps. Another focus was on data for model intercomparison projects (MIPs). Representatives from the Obs4MIPs, Reanal4MIPS, and PCMDI (the IPCC model analysis database) attended and presented each project for discussion. Obs4MIPs and Reanal4MIPs aims to facilitate the use of well-validated and well-documented observations and reanalysis fields for evaluation, validation, or input for climate models. Standardized documentation and formats will be used to ease use with model variables. The WDAC showed strong support for these efforts and will look for ways to facilitate them, including helping to plan future workshops.

International workshop on sea ice concentration presentations available

The 2nd International workshop on sea ice concentration took place on February 18-19 2013 at the Danish Meteorological Institute in Copenhagen sponsored by the European Space Agency (ESA), WCRP Climate and Cryosphere (CliC) Project Office and the Danish Meteorological Institute. The workshop had 4 sessions presenting: user requirements to climate datasets, algorithms and tie-points, validation data and validation and algorithm intercomparison, including discussions on requirements for sea ice concentration and extent and the Sea Ice CCI (SICCI) project development of the methodology for the sea ice essential climate variable (ECV) production. Discussions also addressed how to establish a free and open common validation dataset, what such a dataset should consist of and how it should be organized. The organizing committee was Leif Toudal Pedersen, Danish Meteorological Institute, Georg Heygster, University of Bremen and Stein Sandven, Nansen Environmental Remote Sensing Center. The workshop participants where scientists developing and/or applying algorithms to derive sea ice concentration from satellite microwave radiometry.

Call for Feedback for SOOS Ice Shelf Theme Workplan

At the upcoming SOOS SSC meeting in Shanghai the science theme workplans will be discussed. The workplans are supposed to present what the community have identified as being the gaps in observations/knowledge that SOOS can help fill. Anna Wåhlin has tried to summarize in a draft document the discussions about the Ice Shelf theme workplan from the FRISP meeting in Stockholm and from the Under Ice workshop and various other forum and seeks feedback on the draft before the 9th May. It will then be possible to incorporate the feedback into the document that has to be sent before May 10 (Australian time). All feedback is welcome though, also after the May 9th deadline - this document will serve as aid during the discussions during the meeting on May 20-22 so there will be good opportunity to bring up any feedback provided before the meeting. Send feedbak to: Anna Wåhlin e-mail: .


SOOS Seeing Below the Ice Workshop Videos Available

Videos of plenary presentations and discussions from the Southern Ocean Observing System's Seeing Below the Ice Workshop, held from the 22-25 October, 2012 in Hobart, Australia, are now available. The goal of the workshop was to develop a strategy for sustained observations of the Antarctic sea-ice zone and observe environmental and ecosystem shifts caused by a warming global ocean, while drawing on the expertise of Arctic research, to shed light on a significant science blind spot – how quickly is the sub-ice ocean warming?

SOOS is an endorsed CliC project and paid for video editing and hosting.

AWI-CliC Science Symposium Presentations, Videos and Podcasts Available

As part of the 9th Session of the CliC Scientific Steering Group, held 4-7 February 2013 at the Alfred Wegener Institute (AWI) in Potsdam, Germany, a joint Alfred Wegener Institute of Polar and Marine Research (AWI) / Climate and Cryosphere (CliC) science symposium was held. The afternoon contained talks introducing the AWI, WCRP, IASC, SCAR and new CliC objectives, as well as presentations from researchers in the fields of global and regional climate, sea ice and more. It also featured a presentation by Mark Drinkwater from ESA on some of the latest developments in cryosphere oriented satellites.

Norwegian Polar Institute to Continue to Host the WCRP Climate and Cryosphere Project Office

The Norwegian Polar Institute (NPI) will continue to support the World Climate Research Programme's (WCRP) Climate and Cryosphere (CliC) project office for another 5 years, until year 2018. NPI has been the host institution for CliC since it was established in 2003, and NPI hosted also CliC's predecessor project, the Arctic Climate System Study.  The agreement signed by NPI Director, Jan-Gunnar Winther, and WCRP Director, Ghassem Asrar, in February 2013 confirmed the scientific goal of improving our understanding of the changing cryosphere, and its climate implications that WCRP and CliC have been supporting through international coordination research, modeling and education.

CliC is grateful to NPI and WCRP for their sustained support over the years, and the new directorate staff and the international cryospheric research community look forward to a continued productive collaboration with NPI.

Over the next year, we will be revising the CliC Strategy to reflect the many new developments of our partner and sponsor organizations. We hope that during this process we will receive feedback and guidance from the CliC community.

We would also like to take this time to thank those stepping down from the CliC SSG. Koni Steffen has been an instrumental and charismatic leader for the CliC project for many years and we would like to thank this opportunity to thank him very much for his strong leadership and service. We are happy to report that Koni will continue to be involved in CliC activities on many levels and we thank him for his continued support.  Gino Casassa has also planned a critical role in enhancing CliC activities in South America and as the Vice Chair of CliC. We also thank Sebastian Gerland for many years of great input on sea ice research and, basically, founding the the CliC Arctic Sea Ice Working Group and are pleased that he will remain on it.  We would also like to thank David Bromwich for his highly professional input to a variety of CliC-related issues over these years and we hope that his efforts in the area of polar reanalysis will keep to serve CliC and WCRP.   We would like also to thank Ayako Abe-Ouchi for her input to a number of discussions and hope that CliC could rely on her expertise in the future, particularly in our efforts aimed at supporting the development of ice-sheet models.

The new SSG will meet in Potsdam, Germany from 4-7 February, thanks to the International Arctic Science Committee (IASC) who will be our host.

2nd International workshop on passive microwave sea ice concentration

The workshop will take place on February 18-19 2013 at the Danish Meteorological Institute in Copenhagen and is sponsored by the European Space Agency (ESA), WCRP Climate and Cryosphere (CliC) Project Office and the Danish Meteorological Institute.

Sea ice concentration from satellite microwave radiometry is our primary source of information on the annual sea ice extent minimum as well as a large variety of other properties of the large scale sea ice cover of the Earth. For this workshop we invite scientists developing and/or applying algorithms to derive sea ice concentration to participate in discussions of mutual interest.
The theme of the workshop will be passive microwave sea ice concentration algorithm inter-comparison and validation and we will deal with topics such as algorithm intercomparison, ice concentration validation in different regions and seasons, establishment of a common open validation database, new algorithm developments including fusion of microwave radiometer data with other data sources.
