Record 3 1986-08-06

English

Subject field(s)
  • Air Pollution
  • Statistics
CONT

In comparing the long-term mean of an actual concentration record and that predicted by a long-term model, one cannot expect exact agreement because the time average of the concentration record is not necessarily equal to the time average of the ensemble mean concentration.

OBS

The terms "predicted" and "estimated" are used in opposition with "measured" and "actual".

French

Domaine(s)
  • Pollution de l'air
  • Statistique
CONT

La vérification des modèles après leur calage consiste à comparer les comportements prédits et observés sur un ensemble de "cas" distinct de celui ayant servi au calage : seule cette démarche permet de s'assurer véritablement du pouvoir de prédiction du modèle.
