       + validFrom: `2016-12-13T11:00:00Z` (string, optional) - ISO8601 timestamp notation, means incl. this timestamp; always provide a time offset, e.g. 'Z' for UTC; optional: a request may provide correct offset (so that server can convert to UTC).
       + validUntil: `2016-12-13T12:00:00Z` (string, optional) - ISO8601 timestamp notation, means incl. this timestamp; always provide a time offset, e.g. 'Z' for UTC; optional: a request may provide correct offset (so that server can convert to UTC).
       + validPeriod: `PT0S,PT1H,PT3H,PT6H,PT12H,PT24H` (string, required) - comma separated list of periods to be retrieved. PT1H refers to one hour forecast periods.
