Abstract: Immediately after the March 11, 2011 earthquake and tsunami in Japan we started to continuously survey the Outgoing Long-wavelength Radiation (OLR, 10-13 microns) from NOAA/AVHRR. Our prelim...
Triggering of Aftershocks of the Japan 2011 Earthquake by Earth Tides
Japan 2011 earthquake, Aftershock Triggering, Earth tides
2011/9/1
The aftershock sequence of the devastating Japan earthquake of March 2011 is analyzed for the presence of periodicities at the Earth tide periods. We use spectral analysis as well as a time-domain met...
Global pork markets are becoming more competitive, riding the wind of the bilateral free trade agreement. China is the world’s largest pork producer with nearly 50% of the world’s total production. Ch...

Diurnal variations of polar organic tracers in summer forest aerosols: A case study of a Quercus and Picea mixed forest in Hokkaido, Japan
secondary organic aerosol isoprene 2-methyltetrols levoglucosan
2017/4/12
We investigated the summertime formation of secondary organic aerosols (SOA) via the oxidation of isoprene, α/β-

Chemical and stable isotopic (δD, δ18O, δ34S) compositions of rivers and groundwaters, mineral constituents of rock
samples from wells, and δ34S values of anhydrite in the Izu collision zone and its ...
Characteristics of Atmospheric Elemental Carbon (Char and Soot) in Ultrafine and Fine Particles in a Roadside Environment, Japan
Black carbon (BC) Ultrafine particles Char-EC Soot-EC Diesel exhausts
2016/3/28
Atmospheric carbonaceous components, particularly char and soot in ultrafine particles (UFPs; Dp < 0.1 m) and fine
particles (FPs; Dp < 2.5 m), were measured four times during one...
Epidiceras (Bivalvia, Hippuritoidea) from the Tithonian–Berriasian Torinosu-type Limestones of the Sakawa Area, Southwest Japan
Tithonian–Berriasian Torinosu-type Limestones Sakawa Area

Excavated specimens of two primitive rudists, Epidiceras speciosum (Goldfuss) and Epidiceras guirandi (de Loriol), are systematically described for the first time from the Tithonian-Berriasian Torinos...
Ozone production during the field campaign RISFEX 2003 in the sea of Japan: analysis of sensitivity and behaviour based on an improved indicator
Ozone production the field campaign RISFEX 2003 the sea of Japan an improved indicator
2010/10/21
The ratio Φ=kHC+OH[HC]/kNOx+OH[NOx] is used as an indicator for the sensitivity of ozone production (P(O3)) to HC and NOx in the field campaign RISFEX 2003 (RIShiri Fall EXperiment 2003) at Rishiri Is...
