my question concerns the definition of the grib keys 'validityDate' and 'step' for monthly statistics of seasonal forecast data. In particular, the values for the grib keys 'validityDate' and 'verifyingMonth' in the monthly statistics to me seem to be inconsistent with each other. Take the following example request to get monthly forecasts of 2-m temperature from the UKMO model initialized on 1 July 2022 (nominal start date):
