GroupGroupModelling & Data Assimilation (1)Modelling & Data Assimilation (1)

Action: Convene ice/ocean modeling and data assimilation workshop targeted for late 2002

or early 2003 - location TBD. Summary of workshop outcome to be reported on at IICWG-4 in St. Petersburg.

Prepare ‘the white paper” Responsible:

Dennis Conlon, Doug Lamb, Tom Carrieres, Chad Dick, Dean Flett

Status: International meeting outside of IICWG meeting deferred

until IICWG-4 meeting complete. White Paper prepared for discussion and review at IICWG-

4. IICWG-4 Science Workshop with theme on Modeling and

Data Assimilation to gather opinion and consensus on “Next Steps”

OPEN


GroupGroup

Action: Coordinate and develop project and/or proposal focussing on data assimilation

for submission to funding opportunities. Responsible:

Lars-Anders Breivik, Roger De Abreu, Doug Lamb

Status: No activity. To be revisited upon outcome of science discussions at

IICWG-4 Science Workshop and main meeting. OPEN

GroupGroup

Action: Attend and present summary & inventory of available digital and non-digital ice

service ice archives at ACSYS/CliC-organized Sea Ice Extents Workshop, April'02.

Responsible: TBD (suggestions - Florence Fetterer?; Michail Krasnoperov?; Vasily

Smolyanitsky?)

Status: Florence Fetterer and Vasily Smolyanitsky attended.

Fetterer presented poster entitled “Ice Chart Archive Formats: Progress in the IICWG”. Recommendations from the meeting are expected to lead to better cohesion among groups working on historical sea ice data.

GroupGroup

Status continue: AARI's V.Smolyanitsky delivered a status report describing

both factual historical sea ice material submitted to the WMO project "Global Digital Sea Ice Data Bank" and derived climatic products, primarily based on AARI, CIS and NIC charts. In his report he pointed out on evidences for existence of multi-decadal oscillations and not 2-3 decadal linear trends and as well as possibilities of constructing blended datasets based on data sources from various ice services (Canada, Denmark, Japan, Russia, USA etc.). When constructed those datasets would potentially benefit accuracy of climatic investigations and numerical modelling.

GroupGroupValidation and Analysis (1)Validation and Analysis (1)

Action: Facilitate timely release of preliminary results and findings from the Healy Cruise.

Make data available to other researchers as necessary to support research activities.

Responsible: Doug Lamb

Status: Doug Lamb sent out report entitled “Field Observation of

Arctic Sea Ice - Healy Cruise HY-01-03 - Sea Ice Remote Sensing and Modeling” to CIS, DNMI, and DMI in December, 2001.

Available upon request CLOSED



Action (continuing): Continued coordination for ENVISAT and future Science field validation activities.

Responsible: All

Status: All approved AO PI’s were invited by ESA to begin

ordering ENVISAT data sets as of February 2003. All PI’s encouraged to coordinate activities and share

data sets.(e.g., Polarstern (5/4-19/4/03)+ Aranda (23/4-16/4/03) cruises – EU GreenICE and SITHOS projects – ENVISAT ASAR data acquisition coordination)

OPEN


GroupGroup

Action: Pursue development of project proposal on use of Visible/Infrared data (e.g. for

ice typing, classification, cloud-masking, etc.) for submission to funding opportunities. Investigate opportunity for Visiting Scientist visit to DNMI.

Responsible: Lars-Anders Breivik, Roger De Abreu, Doug Lamb

Status: No activity. To be re-assessed at IICWG-4. OPEN

Validation and Analysis (3)Validation and Analysis (3)



Action: Provide information to the group and coordinate communication on QuikScat

(SeaWinds) data and algorithm access and evaluation. Responsible:

Doug Lamb

Status: NRT ice data available from NOAA/NESDIS QuikSCAT Ice

Page (http://manati.wwb.noaa.gov/cgi-bin/qscat_ice.pl). CLOSED

Improving Accuracy of Ice Charts&

Transition of Science to Operations

Action: Revisit Ice Classification problem. Science groups at each ice centre to consider

own requirements and desired methodology for machine-assisted segmentation and classification and exchange ideas and concepts. Ice agencies to develop regional training and validation data sets to allow for training and/or testing of tools and systems.

Responsible: Science leads/contacts at respective ice services

Status: CIS has scaled back to ice/water separation and R&D for

development of tools to assist in ice analysis work flow NIC has discontinued work on automated ice typing at present DMI automatic ice/water classification with the aid of SAF and

SSM/I-85 GHz ice products – being evaluated. OPEN
