An aggregation of air temperature forecast conditions typically reported together at an aerodrome, including the minimum and maximum anticipated air temperatures and when they occur.<br/><br/>AerodromeAirTemperatureForecast is only reported on base conditions on a TAF, not change forecasts.<br/>

MeteorologicalAerodromeForecastRecord
Class   		Name:  
  		Name: temperature
 
Details:
Minimum and maximum temperatures observed at specific times, consisting of up to a maximum of four temperatures (two maximum temperatures and two minimum temperatures).<br/><br/>Due to Note 9 on Table A5-1: "consisting of up to a maximum of four temperatures (two maximum temperatures and two minimum temperatures)", there can be up to two temperature groups on each MeteorologicalAerodromeForecastRecord.  It is possible that Annex 3 instead specifies four temperatures for the entire TAF but no more than one for each Record, in which case this association would need to be corrected to be 0..1 and a constraint on TAF would need to be put in place to ensure that no more than two temperature forecast groups exist on any single TAF.<br/>
