In the returned data frame each row represents a particular oceanographic or meteorological measurement. The name of the measurement is provided in the first column (Type). The second column, From, provides a timestamp indicating the earliest available data for the measurement. The third column, To, provides the last date and time when the measurement is available. When there are gaps in availability there will be two rows from a given measurement. See the table below as an example.

As of the release of version 0.20.0 there are thirteen stations where the data inventory is missing and an Error will be returned if queried with coops_station_inventory(). The list of stations without a data inventory can be accessed by calling noaaoceans:::known_missing_inventory(). Due to heavy use of JavaScript on data inventory pages and a desire to keep package dependencies to a minimum the list of known stations has been hard coded. Please create an Issue or Pull Request to update the list stations missing data inventory.
