All times are local (unless otherwise noted)
Lidar data from Hawaii, Japan, and Germany generally showed continuing low concentrations of stratospheric aerosols (figure 64. A broad layer centered at about 24 km altitude was detected over Mauna Loa, Hawaii on 26 January, but its profile was not characteristic of newly injected material. At Fukuoka, Japan, peak backscattering increased slightly in December and January, to levels last measured shortly after the May eruption of Banda Api, Indonesia.
No recent eruptions appear to have produced clouds that reached the stratosphere. Observations of the December-January eruption of Lonquimay, Chile from the ground and from weather satellites revealed no clouds exceeding 9 km altitude. Weather conditions hampered observations during the December-January eruption of Tokachi-dake, Japan, and no large eruption clouds were seen, although ash fell tens of kilometers away.
