Journal ArticleDOI
Characteristics of dust aerosols inferred from lidar depolarization measurements at two wavelengths.
Nobuo Sugimoto,Choo Hie Lee +1 more
TL;DR: A simple two-component theory considering two types of aerosol (dust and spherical aerosols) was developed and applied to the observed data and the mixing ratio of dust and the backscatter-related Angström exponents for dust andherical aerosols was derived.
Journal ArticleDOI
Review of ozone and temperature lidar validations performed within the framework of the Network for the Detection of Stratospheric Change

Barnes,Jean-Luc Baray,Hassan Bencherif,Hans Claude,Aleide G. di Sarra,Georgio Fiocco,Georg Hansen,Alain Hauchecorne,Thierry Leblanc,Choo Hie Lee,Shiv R. Pal,Gérard Mégie,Hideaki Nakane,Roland Neuber,Wolfgang Steinbrecht,Jeffrey P. Thayer +21 more
TL;DR: The synthesis of the published works shows that the NDSC network can potentially be considered as homogeneous within +/-2% between 20-35 km for ozone and +/-1 K between 35-60 km for temperature, and outside this altitude range, larger biases are reported and more efforts are required.
Journal ArticleDOI
Study of Asian Dust Phenomena in 2001–2003 Using A Network of Continuously Operated Polarization Lidars
Nobuo Sugimoto,Atsushi Shimizu,Ichiro Matsui,Itsushi Uno,Kimio Arao,Xuhui Dong,Shuli Zhao,Jun Zhou,Choo Hie Lee +8 more
TL;DR: In this article, a method using the depolarization ratio for estimating the contributions of Asian dust and spherical air-pollution aerosols in observed aerosol mixtures was developed.
Journal ArticleDOI
Long-Range Transport of Saharan Dust to East Asia Observed with Lidars
Chan Bong Park,Chan Bong Park,Nobuo Sugimoto,Ichiro Matsui,Atsushi Shimizu,Boyan Tatarov,Akihide Kamei,Choo Hie Lee,Itsushi Uno,Toshihiko Takemura,Douglas L. Westphal +10 more
TL;DR: The results with the global models reproduced the dust layer qualitatively, but the regional model did not This suggests the source of the dust layers is located outside of the modeled region of a regional model that includes Taklimakan Desert and Gobi Desert as mentioned in this paper.
Proceedings ArticleDOI
Measurement of Asian dust by using multiwavelength lidar
TL;DR: In this article, the backscattering ratio of aerosol and Asian dust shows similar value that is in the range of 1.2 to 3, but the values of depolarization ratio is large that over 15% of Asian dust than below 10% of aerosols.
