There exists a precursor in the OI 630.0 nm dayglow which enables the prediction of ESF at least 3 hours prior to its actual occurrence and hence points to the significant control of daytime EIA‐related processes in the triggering of the post‐sunset ESF.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380848661784278408","@type":"Researcher","foaf:name":[{"@value":"R.
