Abstract
Solar EUV radiation is one of the sources for atmospheric density variation in thermosphere.NRLMSISE-00 model is widely used to simulate the density variation in the satellite orbit.However,this model always exhibits large density errors compared with satellite observations.In this work,the model output is compared with CHAMP satellite observation on the same position,and an ideal value of proxy for solar EUV (F*) is chosen through changing the input F10.7.Further investigation shows that F* is closely related to another solar EUV index MgII.By using of neuron network technique,the correspondence relationship between the new proxy of solar EUV (Feuv)and F10.7 and MgII.The target parameter is F*.The new proxy substitutes F10.7,and is input into NRLMSISE-00 model.The results show the difference of thermosphere density between those detected by CHAMP and GRACE-A satellite and that calculated by the NRLMSISE-00 model is dropped significantly.关键词
