Journal ArticleDOI
Urban photochemistry in central Tokyo 1. Observed and modeled OH and HO2 radical concentrations during the winter and summer of 2004
Yugo Kanaya,Renqiu Cao,Hajime Akimoto,M. Fukuda,Yuichi Komazaki,Yoko Yokouchi,Makoto Koike,Hiroshi Tanimoto,Nobuyuki Takegawa,Yutaka Kondo +9 more
TL;DR: In this paper, the authors used laser-induced fluorescence to measure the concentrations of OH and HO2 radicals in central Tokyo during two intensive campaigns (IMPACT IV and IMPACT L) in January-February and July-August 2004.
Journal ArticleDOI
Evolution of mixing state of black carbon particles: Aircraft measurements over the western Pacific in March 2004
Nobuhiro Moteki,Yutaka Kondo,Yuzo Miyazaki,Nobuyuki Takegawa,Yuichi Komazaki,Gakuji Kurata,T. Shirai,Donald R. Blake,Takuma Miyakawa,Makoto Koike +9 more
TL;DR: Moteki et al. as mentioned in this paper found that BC particles with a core diameter of 250 nm increased at a slower rate of 1.0.63 within 12 hours (h),namely 2.3%h 1,afterbeingemitted from the Nagoya urban area in Japan.
Journal ArticleDOI
Consistency and Traceability of Black Carbon Measurements Made by Laser-Induced Incandescence, Thermal-Optical Transmittance, and Filter-Based Photo-Absorption Techniques
Yutaka Kondo,Lokesh K. Sahu,Nobuhiro Moteki,Firoz Khan,Nobuyuki Takegawa,X. Liu,Makoto Koike,Takuma Miyakawa +7 more
TL;DR: In this paper, the volatilities of 13 organic compounds passed through a heated inlet were used to quantify the interference of pyrolyzed refractory organics on the BC measured with a filter-based absorption photometer continuous soot monitoring system.
Journal ArticleDOI

Hanwant B. Singh,D. Herlth,R. Kolyer,Louis J. Salas,John D. Bradshaw,Scott T. Sandholm,Douglas D. Davis,James H. Crawford,Y. Kondo,Makoto Koike,Robert W. Talbot,Gerald L. Gregory,G. W. Sachse,Edward Browell,Donald R. Blake,F. S. Rowland,Reginald E. Newell,John T. Merrill,Brian G. Heikes,Shaw Chen Liu,Paul J. Crutzen,Maria Kanakidou +21 more
TL;DR: In this paper, a global three-dimensional photochemical model has been used to compare observations with predictions and to assess the significance of major sources of atmospheric NOx in the western Pacific.
Journal ArticleDOI
