Validation Test Report for LAGER 1.0

Abstract

LAGER v1.0 (Local Automated Glider Editing Routine) is the first version of an ocean glider quality control system developed for the Naval Oceanographic Office (NAVO) Glider Operations Center. The LAGER v1.0 methods and operation are fully documented in the LAGER Manual (Carnes, 2008), which is included here as an Appendix. LAGER was developed to import raw data returned from ocean gliders, to detect and flag erroneous observations, and to reformat data and flags into a standard NAVO format. This report documents a validation of the automated portion of LAGER v1.0 using temperature and salinity observations from four Slocums and four Seagliders operated by NAVO during the RIMPAC08 exercise conducted near Hawaii in July 2008. The validation results from 3657 profiles showed that the automated quality control selected 8.2% of the profiles for further manual review. Of the remaining profiles, only 13 had undetected errors, and all but one was of a minor type that can be corrected in the next version of LAGER.
