anchor.diff:  + The mostLikelyLowAirTemperature equals minAirTemperature minus airTemperatureError.
   + min/maxAirTemperature
       + The min/maxAirTemperature parameters for the PT3H, PT6H are calculated as a min/max value of the airTemperature parameter for previous 3 and 6 hours respectively.
  -    + The minAirTemperatureInCelsius parameter for the PT12H is calculated using the following formula  
  +    + The minAirTemperatureInCelsius parameter for the PT12H is calculated using the following formula
           minAirTemperatureInCelsius = -2.46934 + 0.85674 * minAirTemperatureInCelsiusValueForPrevious12Hours + 0.10476 * maxAirTemperatureInCelsiusValueForPrevious12Hours + 0.03747 * windSpeedInKnotsValueInTheMiddleOf12HourPeriod + 0.23575 * effectiveCloudCoverInOctaValueInTheMiddleOf12HourPeriod + 0.02364 * effectiveCloudCoverInOctaValueAtTheEndOf12HourPeriod
  -    + The maxAirTemperatureInCelsius parameter for the PT12H is calculated using the following formula  
  +    + The maxAirTemperatureInCelsius parameter for the PT12H is calculated using the following formula
           maxAirTemperatureInCelsius = 0.566 + 1.01062 * maxAirTemperatureInCelsiusValueForPrevious12Hours + 0.0289 * totalCloudCoverInOctaInTheMiddleOf12HourPeriod -0.03689 * lowCloudCoverInOctaInTheMiddleOf12HourPeriod - 0.0162 * minAirTemperatureInCelsiusValueForPrevious12Hours
       + The min/maxAirTemperature parameter for the PT24H is calculated as min/max value of two previous PT12H min/maxAirTemperature values respectively.
   + The maxUVIndexWithClouds parameter is calculated as a maximum of hourly values
  
positive.code: + 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).
