Abstract Taking 2012 January data as an example，effect of model order and observation data sampling intervals on global ionospheric modeling time and accuracy of the model，and the correlation between the magnetic field intensity and the accuracy of the model were analized.The results show that the model order and the sampling interval affect greatly modeling time and accuracy of the model，and there is a strong correlation between the geomagnetic intensity and the accuracy of the model.Therefore，reducing model order and sampling rate can greatly reduce the modeling time required duaring the geomagnetic quiet perids.
Key words ：
global ionospheric maps
model order
sampling interval
geomagnetic field
accuracy
