3 years ago The following tables contain OSCAR/Requirement variables, which are missing in the WIGOS vocabulary (and not yet included in another issue).

OSCAR/Requirements uses a list of variables that is not fully re-conciled with the official list of variables as found on codes.wmo.int/wmdr. Moreover, these variable also use numeric codes, but different numbers. Thus, not only are the entries partly different, but there is a risk that users may refer to a variable intended for machine-based metadata management in OSCAR/Surface from the list of OSCAR/Requirements. A concerted effort is needed to
