夕方側のサブオーロラ帯で稀に見られる STEVE (Strong Thermal Emission Velocity Enhancement) という紫色のオーロラによく似た発光現象が、オーロラ帯の朝側でも見られるかもしれない、というのが本研究の主たる結果である。発見された現象は、図1に示すように緑色のオーロラの北（高緯度）側に出現した。この発見について、欧州宇宙機関 (ESA: European Space Agency) からプレスリリースを行い、そこでこの現象を「STEVE’s twin」と呼称したため、今回の記事でも「双子」と表現することにする。STEVE が発生する夕方側のサブオー...

Geomagnetic field data have been widely used by scientists to gain deeper insight of Earth’s interior's activities and the surrounding space environment. We have been utilizing ground-based magnetometer data provided by Magnetic Data Acquisition System (MAGDAS) of Kyushu University in exploring ear...

In upper atmospheric research field, interdisciplinary studies by using various observational data are needed. Then the key for connecting various kinds of data is metadata. In Japan, Inter-university Upper atmosphere Global Observation NETwork(IUGONET) has released their metadata database to the p...
Combining geometrical optics (GO) and wave optics (WO), the COSMIC data analysis and archive center (CDAAC) retrieved two sets of dry atmosphere temperatures (T) from COSMIC GPS radio occultation (GPS-RO), which are called atmPrf2010 and atmPrf2013. In atmPrf2010, the sewing height between WO and G...
