netCDF Inventory — sg014_20040924T182454_delayed

OG1: 15 of 16 mandatory global attributes present · 7 highly-desirable missing — presence, not validity; each category below shows the values and flags a missing mandatory attribute in amber.

33 data variables, 0 sensors, 8 QC-flag variables (shown in the QC section, not listed here), 4 coordinates.

8 of 33 data variables carry a _QC companion.

(2) Spatiotemporal coverage

Computed values are the min/max over the records in this file. The first profile is number 350, so this file is a subset — these ranges need not match the full mission.
