In geophysics, the free-air gravity anomaly, often simply called the free-air anomaly, is the measured gravity anomaly after a free-air correction is applied to account for the elevation at which a measurement is made. It does so by adjusting these measurements of gravity to what would have been measured at a reference level, which is commonly taken as mean sea level or the geoid.

  • في الجيوفيزياء ، شذوذ جاذبية الهواء الحر ويُطلق عليه غالبًا شاذة الهواء الحر ويعرف بأنه شذوذ الجاذبية المقاس بعد تطبيق تصحيح الهواء الحر لتصحيح الارتفاع الذي يتم عنده القياس عن طريق تعديل قياسات الجاذبية إلى ما كان يمكن قياسه عند مستوى مرجعي. بالنسبة للأرض ، يُؤخذ هذا المستوى المرجعي عمومًا على أنه متوسط مستوى سطح البحر.

  • In gravimetria, si definisce anomalia in aria libera la differenza fra l'accelerazione di gravità rilevata sperimentalmente in un punto e quella teorica, calcolata tenendo conto della differenza di quota del caposaldo di misura rispetto al su cui è definita l'accelerazione di gravità standard. Nel caso di misure condotte sulla superficie terrestre, ad esempio, tale livello convenzionale è costituito dal cosiddetto ellissoide di riferimento. L'espressione "aria libera" indica il fatto che si trascura l'eventuale presenza di masse fra la quota di riferimento e quella del caposaldo di misura. (it)

L'espressione "aria libera" indica il fatto che si trascura l'eventuale presenza di masse fra la quota di riferimento e quella del caposaldo di misura. Il valore teorico della correzione in aria libera, ovvero della quantità da sommare all'accelerazione gravitazionale al livello di riferimento per ricavare l'accelerazione gravitazionale che ci si aspetterebbe di rilevare alla quota del caposaldo di misura, può essere quantificato come Sostituendo i valori di e caratteristici della superficie terrestre, si calcola (it)
