1 NSIDC Passive Microwave Cryosphere Science Data Product Metrics Prepared by the ESDIS SOO Metrics Team for the Cryosphere Science Data Review January 11-12, 2006

2 PM NSIDC 010306.ppt 2 Purpose Complements the data products table of metrics Presents the discipline data by significant parameters –# of products, archive, distribution, # of users Allows reviewers to distinguish individual products for further analysis

3 PM NSIDC 010306.ppt 3 Non-ECS Product Data Metrics Summary FieldDefinitionAcronym Product IDIdentifier assigned to a product Product NameProduct name and short description LevelProduct processing level InstrumentName of an EOS instrument MissionName of EOS mission CategoryGrouping code for related products Archive DateDate when a product was inserted in the archive Granules ArchivedTotal granules stored as of 09/30//2005 and granules archived per FYGA Archive VolumeTotal storage (GBs) as of 09/30/2005 and amount archived per FYAV Distinct End Users per Product per FY Counts of unique users of a product within a FYUU Total End Users per Product per FY A simple sum of the data across all FYs; it does not rectify for unique users across the entire range UU Total Distribution Granules per Product per FY & Total Total granules distributed as of 09/30//2005 and granules distributed per FYDG Distribution Volumes per Product per FY & Total Total volume (GBs) distributed as of 09/30/2005 and amount distributed per FYDV BaseData prior to FY03

4 PM NSIDC 010306.ppt 4 Sample Science Data Product Review Charts and Tables Standard set of charts & tables –Table characterizing the discipline data set –Detailed descriptions of products –Archive volume of discipline data by product level –Focus on Product Subsets Product by End User, Product by Archive Volume Table of products with selected parameters –Scatter plots (3) of Products by demand and distribution parameters –Sample time profiles Archive, distribution, and users by FY Single product or data set
