During the 2002 Spring and Summer Cruises of SBI all HRPT and DMSP overpasses of the USCGC Healy were archived to tape. These files were collected with a Terascan receiving system aboard the Healy as it cruised the Bering and Chukchi Seas. These data are archived as pass files on 4mm DDS-3 tapes using the Terascan archive function. Please see the accompanying documentation files for the spring cruise and the summer cruise for a complete catalog of overpasses on each tape. To order these data, please e-mail your request to Greg Stossmeister at firstname.lastname@example.org.
