   + The minVisibilityInMeter parameters for PT3H, PT6H, PT12H and PT24H are calculated as a min value of the visibilityInMeter parameter from PT0S for the last 3, 6, 12 and 24 hours respectively,
       including marginal values. E.g for PT3H period 4 PT0S values are used to cover the full three hours (validUntil-3h,validUntil-2h,validUntil-1h and validUntil).
  ++ The min/max FeelsLikeTemperatureIn Celsius/Fahrenheit/Kelvin parameters for PT3H, PT6H, PT12H and PT24H are calculated as a min/max value of the feelsLikeTemperatureIn Celsius/Fahrenheit/Kelvin parameter from PT0S for the last 3, 6, 12 and 24 hours respectively, including marginal values. E.g for PT3H period 4 PT0S values are used to cover the full three hours (validUntil-3h,validUntil-2h,validUntil-1h and validUntil).
