Compared with the previous statistical results about EMIC waves, the occurrence rates of EMIC waves distribute relatively uniform in the MLT sectors in lower <jats:italic>L</jats:italic> shells. On the other hand, in higher <jats:italic>L</jats:italic> shells, there are indeed some peaks of the occurrence rate for the EMIC waves, especially in the noon, dusk, and night sectors. EMIC waves appear at lower <jats:italic>L</jats:italic> shells in the dawn sector than in other sectors. In the lower <jats:italic>L</jats:italic> shells (<jats:italic>L</jats:italic> < 4), the occurrence rates of EMIC waves are significant in the dawn sector. This phenomenon may result from the distribution characteristics of the plasmasphere. The location of the plasmapause is usually lower in the dawn sector than that in other sectors, and the plasmapause is considered to be the favored region for the generation of EMIC waves. In higher <jats:italic>L</jats:italic> shells (<jats:italic>L</jats:italic> > 4) the occurrence rates of EMIC waves are most significant in the dusk sector, implying the important role of the plasmapause or plasmaspheric plume in generating EMIC waves. We have also investigated the distribution characteristics of the hydrogen band and the helium band EMIC waves. Surprisingly, in the inner magnetosphere, the hydrogen band EMIC waves occur more frequently than the helium band EMIC waves. Both of them have peaks of occurrence rate in noon, dusk, and night sectors, and the hydrogen band EMIC waves have more obvious peaks than the helium band EMIC waves in the night sector, while the helium band EMIC waves are more concentrated than the hydrogen band EMIC waves in the dusk sector. Both of them occur significantly in the noon sector, which implies the important role of the solar wind dynamic pressure.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380011142935148297","@type":"Researcher","foaf:name":[{"@value":"Dedong Wang"}],"jpcoar:affiliationName":[{"@value":"School of Electronic Information Wuhan University  Wuhan China"}]},{"@id":"https://cir.nii.ac.jp/crid/1380011142935148288","@type":"Researcher","foaf:name":[{"@value":"Zhigang Yuan"}],"jpcoar:affiliationName":[{"@value":"School of Electronic Information Wuhan University  Wuhan China"}]},{"@id":"https://cir.nii.ac.jp/crid/1380011142935148298","@type":"Researcher","foaf:name":[{"@value":"Xiongdong Yu"}],"jpcoar:affiliationName":[{"@value":"School of Electronic Information Wuhan University  Wuhan China"}]},{"@id":"https://cir.nii.ac.jp/crid/1380011142935148292","@type":"Researcher","foaf:name":[{"@value":"Xiaohua Deng"}],"jpcoar:affiliationName":[{"@value":"School of Electronic Information Wuhan University  Wuhan China"},{"@value":"Institute of Space Science and Technology Nanchang University  Nanchang China"}]},{"@id":"https://cir.nii.ac.jp/crid/1380011142935148296","@type":"Researcher","foaf:name":[{"@value":"Meng Zhou"}],"jpcoar:affiliationName":[{"@value":"Institute of Space Science and Technology Nanchang University  Nanchang China"}]},{"@id":"https://cir.nii.ac.jp/crid/1380011142935148293","@type":"Researcher","foaf:name":[{"@value":"Shiyong Huang"}],"jpcoar:affiliationName":[{"@value":"School of Electronic Information Wuhan University  Wuhan China"}]},{"@id":"https://cir.nii.ac.jp/crid/1380011142935148294","@type":"Researcher","foaf:name":[{"@value":"Haimeng Li"}],"jpcoar:affiliationName":[{"@value":"School of Electronic Information Wuhan University  Wuhan China"}]},{"@id":"https://cir.nii.ac.jp/crid/1380011142935148290","@type":"Researcher","foaf:name":[{"@value":"Zhenzhen Wang"}],"jpcoar:affiliationName":[{"@value":"School of Electronic Information Wuhan University  Wuhan China"}]},{"@id":"https://cir.nii.ac.jp/crid/1380011142935148289","@type":"Researcher","foaf:name":[{"@value":"Zheng Qiao"}],"jpcoar:affiliationName":[{"@value":"School of Electronic Information Wuhan University  Wuhan China"}]},{"@id":"https://cir.nii.ac.jp/crid/1380011142935148291","@type":"Researcher","foaf:name":[{"@value":"C.
