There is no pressure variable in the .nc files. This should be a coordinate.

Missing data should be annotated.

CP01CNSM-RID26-07-NUTNRB000

Data generally look suspect for all deployments of this instrument (the ISUS model) because of the prevalence of negative values. The dataset should be annotated if there is a known issue with this instrument to inform users if all or some data should be considered suspect.

Annotation ID 709 "Short deployment due to the fuel cell not functioning correctly" should be updated to indicate that this refers to deployment 2, and data aren't expected from most instruments for this time period.
