Just the Facts• First Workshop on EOS Snow & Ice Products held

November 16-17, 2004 in Landover, MD• Jointly sponsored by NASA/GSFC (Dorothy Hall) and

NSIDC (Marilyn Kaminski), with support from NASA/HQ, MODIS, and Raytheon

• ~90 attendees Government Academic Industry International

• Presentations, panel discussions, poster sessions, and demonstrations … a broad mix of topics with good opportunity for interaction

• Very well received and appreciated by participants

Panels

• Modeling (Robert Dickinson) “Snow in Climate Models”

• Data Fusion (Dave Robinson) “Blended Snow Mapping”

• Sea Ice (Mike Van Woert) “Sea Ice Remote Sensing in the NPOESS Era: A

Glance at the Past – the Challenge for the Future”

Common theme of discussion:- Need for timely quality data products to

use alone or blended with other products

Workshop Discussions• Validation should be an integral part of

algorithm and product development Recognized tradeoff between science and validation

when resources are limited• Error estimates are necessary for evaluating

derived geophysical products, particularly for construction of CDRs

• CDRs need to be constructed and maintained for consistent quality

• No major data gaps were identified

Future Directions

• Summary article was accepted by EOS and will be published in a few weeks

• NSIDC should continue to support this workshop, in conjunction with NASA or other co-sponsor Biannual seems most reasonable frequency East Coast location gets good support from NASA;

more central location may enable participation from greater number of academics
