2. Jan. 17, 2007 - Wolfe 3 Getting MODIS Data Order from DAAC through EOS Data Gateway –response is a few hours –services (e.g. subsetting) available for some products Get data from DAAC data pools –most recently produced data are on- line and available via FTP Get data from other sources (LAADS, Science team sites, MODIS Rapid Response, direct broadcast, etc.) DAAC Unique Ordering Interfaces

12. Jan. 17, 2007 - Wolfe 13 Geographic and Parameter Subsetting Allows for custom design of delivered products, reducing bandwidth and researcher storage requirements Parameter subsetting particularly valuable for “fat” Level-3 Atmosphere products Involves some delay for file preparation, but runs rapidly in a disk-to-disk environment Subsetting engine is prototype for future “custom” products

13. Jan. 17, 2007 - Wolfe 14 Ordering and Acquiring Data Availability: L1 & Atmosphere products immediately available by ftp Search and order will stage data immediately Exceptions: Only last 30 days of L1B data online (request by POD) Post-processing is needed to subset by parameter (SDS) or geography
