Other AbstractMaking calibration on the atmospheric model density is an important way to improve the accuracy of atmospheric model.By using the atmospheric density data derived from the high-accuracy accelerometer onboard satellite CHAMP,a calibration on NRLMSISE-00 model is developed with the spherical method.Firstly,the atmospheric density is assimilated to the same altitude,then the calibration and prediction error are calculated based on the calibration results.Finally,the atmospheric density of the next 3 days are forcasted.The results show that the calibration and prediction errors are reduced significantly after the spherical calibration.The calibration error is reduced to about 10% during high solar activity year,and the prediction accuracy is improved by 31.34%,21.39%,13.75% for the next 3 days respectively.The calibration error is reduced to about 14% during low solar activity year,and the prediction accuracy is improved by 55.03%,47.79%,43.60% for the next 3 days respectively.
