Units with the namespace "nwsUnit" are currently custom and do not align to any standard.
Units with no namespace or the namespace "uc" are compliant with the Unified Code for Units of Measure syntax defined at https://unitsofmeasure.org/. This also aligns with recent versions of the Geographic Markup Language (GML) standard, the IWXXM standard, and OGC Observations and Measurements v2.0 (ISO/DIS 19156).
Namespaced units are considered deprecated. We will be aligning API to use the same standards as GML/IWXXM in the future.

# components.headers.CorrelationId.description
A unique identifier for the request, used for NWS debugging purposes. Please include this identifier with any correspondence to help us investigate your issue.

# components.headers.RequestId.description
A unique identifier for the request, used for NWS debugging purposes. Please include this identifier with any correspondence to help us investigate your issue.

# components.headers.ServerId.description
The identifier of the server that generated the response, used for NWS debugging purposes. Please include this identifier with any correspondence to help us investigate your issue.

# components.headers.X-Api-Key.description
A token that a client provides when making API calls.  Please include this identifier with any correspondence to help us investigate your issue.

# components.securitySchemes.userAgent.description
We require that all consumers of the API include a User-Agent header in requests. This is due to a high number of scripts exhibiting abusive behavior (intentional or unintentional). We recommend setting the value to something that identifies your application and includes a contact email. This will help us contact you if we notice unusual behavior and also aid in troubleshooting issues.
The API remains open and free to use and there are no limits imposed based on the User-Agent string.
This mechanism will be replaced with a more typical API key system at a later date.

# components.securitySchemes.apiKeyAuth.description
We are testing including a more traditional API Key system on certain endpoints.  This is due to a large change in the weather.gov site.
The API remains open and free to use and there are no limits imposed based on the X-Api-Key string.
